Scientists and doctors are calling for a new national policy in Japan that mandates the testing of food, soil, water, and the air for radioactivity still being emitted from Fukushima's heavily damaged Daiichi nuclear power plant."How much radioactive materials have been released from the plant?" asked Dr Tatsuhiko Kodama, a professor at the Research Centre for Advanced Science and Technology and Director of the University of Tokyo's Radioisotope Centre, in a July 27 speech to the Committee of Health, Labour and Welfare at Japan's House of Representatives. "The government and TEPCO have not reported the total amount of the released radioactivity yet," said Kodama, who believes things are far worse than even the recent detection of extremely high radiation levels at the plant. There is widespread concern in Japan about a general lack of government monitoring for radiation, which has caused people to begin their own independent monitoring, which are also finding disturbingly high levels of radiation. Kodama's centre, using 27 facilities to measure radiation across the country, has been closely monitoring the situation at Fukushima - and their findings are alarming.According to Dr Kodama, the total amount of radiation released over a period of more than five months from the ongoing Fukushima nuclear disaster is the equivalent to more than 29 "Hiroshima-type atomic bombs" and the amount of uranium released "is equivalent to 20" Hiroshima bombs.

Kodama, along with other scientists, is concerned about the ongoing crisis resulting from the Fukushima situation, as well as what he believes to be inadequate government reaction, and believes the government needs to begin a large-scale response in order to begin decontaminating affected areas.Distrust of the Japanese government's response to the nuclear disaster is now common among people living in the effected prefectures, and people are concerned about their health.Recent readings taken at the plant are alarming.When on August 2nd readings of 10,000 millisieverts (10 sieverts) of radioactivity per hour were detected at the plant, Japan's science ministry said that level of dose is fatal to humans, and is enough radiation to kill a person within one to two weeks after the exposure. 10,000 millisieverts (mSv) is the equivalent of approximately 100,000 chest x-rays.

t is an amount 250 per cent higher than levels recorded at the plant in March after it was heavily damaged by the earthquake and ensuing tsunami. The operator of Japan's crippled Fukushima Daiichi nuclear power plant, Tokyo Electric Power Company (TEPCO), that took the reading, used equipment to measure radiation from a distance, and was unable to ascertain the exact level because the device's maximum reading is only 10,000 mSv. TEPCO also detected 1,000 millisieverts (mSv) per hour in debris outside the plant, as well as finding 4,000 mSv per hour inside one of the reactor buildings.

External radiation is not counted in this number, as opposed to their draft plan in July which did include external radiation, and it is in addition to the natural radiation exposure (by which is meant pre-Fukushima natural).The experts on the Commission didn't rule on the radiation limit for children, leaving the decision to the Ministry of Health and Labor as if the top-school career bureaucrats in the Ministry would know better.Yomiuri and other MSMs are spinning it as "tightening" the existing provisional safety limits on food.From Yomiuri Shinbun (10/27/2011):

The Food Safety Commission under the Cabinet Office has been deliberating on the health effect of internal radiation exposure from the radioactive materials in food. On October 27, it submitted its recommendation to set the upper limit on lifetime cumulative radiation from food at 100 millisieverts.

On receiving the recommendation, the Ministry of Health and Labor will start setting the detailed guidelines for each food items. They are expected to be stricter than the provisional safety limits set right after the Fukushima I Nuclear Plant accident. The Radiation Commission under the Ministry of Education will review the guidelines to be set by the Ministry of Health and Labor, and the new safety limits will be formally decided.

In KING 5 TV's report Tuesday on high levels of radiation detected in Northwest rainwater, the United States government is accused of continuing to fail to tell the public about Fukushima dangerous radiation blanketing parts of the United States, a coverup that led grassroots projects and independent reporters to gather and present data for public well-being.

Jerry Cuttler, a tireless researcher on the topic of the health effects of low level radiation, sent me an article titled Toward Improved Ionizing Radiation Safety Standards from the July 2011 issue of Health Physics, a peer-reviewed journal about radiation safety. (Unfortunately, like many peer reviewed journals, Health Physics is not available for free online. It is possible to purchase individual articles or to gain access if you have a membership or access to a university or corporate library.)

he article explains in clear, but scientific terms, how radiation at low average levels can result in increasing the latency period of cancer development past the end of a natural lifespan. We all have the potential for developing cancer, but we also have finite lives. Dr. Raabe’s research has led him to the conclusion that low average doses of radiation that might add up to a substantial cumulative dose do not kill off cancer cells, but they delay the ability of those cells to do any real damage until after their host organism is dead from other causes anyway.

Clearly the development of a radiation-induced malignant tumor from either protracted ionizing radiation exposures or acute exposures is not the result of a single random interaction of the ionizing radiation with an isolated cell. Hence, the term stochastic as used by the ICRP (International Commission on Radiological Protection) is not appropriate. The following conclusions indicate that major revisions of the ICRP methodology and standards are needed, and other currently accepted ionizing radiation risk models should be improved to provide more meaningful and realistic estimates of ionizing radiation cancer risk: Cancer induction risk associated with protracted or fractionated ionizing radiation exposure is a non-linear function of lifetime average dose rate to the affected tissues and exhibits a virtual threshold at low lifetime average dose rates;

Professor Kodama is the head of the Radioisotope Center at the University of Tokyo.Professor Kodama's anger is now directed toward the government's non-action to protect people, especially children and young mothers, from internal radiation exposure. His specialty is internal medicine using radioisotope, so he says he has done the intense research on internal radiation:

I have been in charge of antibody drugs at the Cabinet Office since Mr. Obuchi was the prime minister [1998-]. We put radioisotopes to antibody drugs to treat cancer. In other words, my job is to inject radioisotopes into human bodies, so my utmost concern is the internal radiation exposure and that is what I have been studying intensely.

The biggest problem of internal radiation is cancer. How does cancer happen? Because radiation cuts DNA strands. As you know, DNA is in a double helix. When it is in a double helix it is extremely stable. However, when a cell divides, the double helix becomes single strands, doubles and becomes 4 strands. This stage is the most vulnerable.

As efforts to end the nuclear disaster at Tokyo Electric Power Co.'s Fukushima No. 1 nuclear power plant drag on, it is important for the central and local governments to step up their efforts to closely examine the health conditions of people concerned and to decontaminate areas contaminated by radiation.

The people who have been most affected by radiation from the Fukushima plant are workers, both from Tepco and from subcontractors, who have been trying to bring the radiation-leaking plant under control. In the nation's history, these workers rank second only to the victims of the atomic bombings of Hiroshima and Nagasaki in terms of their exposure to radiation, therefore the possibility cannot be ruled out that they will develop cancer. Tepco and the central government must do their best to prevent workers' overexposure to radiation and take necessary measures should workers become overexposed to radiation. It is of great concern that little has been disclosed regarding the conditions of the workers at the Fukushima No. 1 nuclear power plant. Tepco and the central government should disseminate information on the actual working conditions of these people, even if such information seems repetitious and includes what they regard as minor incidents. People are forgetful. They need to be informed. Such information will help raise people's awareness about the issue of radiation and its impact on health.

It must not be forgotten that exposure to radiation has long-term effects on human health. In the Hiroshima and Nagasaki atomic bombings, the number of leukemia cases started to increase among bombing survivors two years after the bombs were dropped. In the case of the 1986 Chernobyl accident, thyroid cancer began to appear among children several years after the disaster happened. Particular attention should be paid to the health of children. In view of these facts, it is logical that the Fukushima prefectural government has developed a program to monitor the health of all residents in the prefecture, who number about 2 million, throughout their lifetime. It has also started examining the thyroids of some 360,000 children who are age 18 or younger. Detailed and long-term area-by-area studies should be carried out to record cancer incidences. In August, the Nuclear Safety Commission of Japan estimated that the Fukushima accidents released a total of 570,000 terabecquerels of radioactive substances, including some 11,000 terabecquerels of radioactive cesium 137.

In the first few days of Japan’s nuclear crisis this spring, the U.S. military wasn’t fully prepared to deal with possible radiation exposure to its troops and equipment, the top U.S. general in Japan said Wednesday.

U.S. Forces Japan commander Lt. Gen. Burton M. Field talked about the radiation risk to U.S. troops during a briefing on Operation Tomodachi for members of the American Chamber of Commerce in Japan on Wednesday.

“As the (Fukushima Dai-ichi) reactors exploded and they sent some of that radiation out, we had the issue with it being detected off shore by the Navy,” he said. “We had to start dealing with the kind of environment that the U.S. military had not really worked in, so we didn’t have the strictest guidelines on what kind of risk we would take in terms of radiation exposure for our (service) members.”

The rainwater data is just one example of failings in how Canada monitored radiation from Fukushima. The accident has exposed a pattern of nonchalance and seeming willful ignorance on the part of Canadian health authorities when it comes to the dangers of nuclear power. Drinking water is another example. In Vancouver, the city did its first test of the drinking-water supply on March 16, a few days after the Fukushima accident on March 11. No radiation was detected in that day’s sample. But this was to be expected because it took until March 18 and 19 for the radioactive plume from Fukushima to first hit the west coast of Canada. Instead of continuing with frequent monitoring, the city didn’t do another radiation test until March 25—nine days after the first test. On March 25, testing detected alpha radiation at 0.11 becquerels per litre in the drinking water at the city’s Seymour-reservoir intake. Alpha radiation comes from isotopes like plutonium-238 and is the most dangerous form of radiation when ingested or inhaled. The level at the Seymour intake was lower than the current Canadian and World Health Organization guideline of 0.5 becquerels per litre in drinking water. On the other hand, the WHO guideline used to be 0.1 Bq per litre before it was adjusted higher in the mid-2000s.

That nine-day hole between March 16 and 25 is exactly when SFU prof Starosta found massive radiation spikes in rainwater in Burnaby. Did the alpha radiation ever surpass the ceiling? We can’t say for sure. Because of the long gap between tests, it’s not clear how high radiation levels may have gotten and for how long. When the city tested its drinking water again on March 28, the alpha radiation was no longer detectable. Food is another big question mark. The Canadian Food Inspection Agency briefly tested Japanese food imports from the area around Fukushima, but it dropped those measures in June. Canada now relies on Japanese authorities to screen contaminated food. But Japan’s food inspections have proven to be highly controversial since Fukushima. The country has no centralized food-inspection system, and poor monitoring after Fukushima allowed food contaminated with radiation to be sold to Japanese consumers.

Meanwhile, it’s becoming clear that the radiation has spread much farther across Japan than government officials have acknowledged. Citizen monitoring groups have found 22 “hot spots” in Tokyo where radiation levels are higher than the level at which zones were considered contaminated near Chernobyl, the New York Times reported on October 14. The CFIA also told the Straight it has no plans to monitor food products from the Pacific Ocean fishery. You’d think this would be a concern, because many fish caught in the Pacific still have large amounts of radiation months after the accident, according to data reported on the website of the Japanese government fisheries agency. In September, 21 Japanese fish catches exceeded the Japanese radiation ceiling—the same number as in August. Two catches in September exceeded the ceiling for radioactive cesium by more than four times.

Part 2: Workers Pushed to Their Limits TEPCO is preparing to spend decades in J-Village. Workers have spread gravel around the large soccer stadium and in a number of adjacent areas. Here they have placed row after row of gray trailers. There are 40 per row and they sit two stories high, extending right up to the blue plastic seats in the stands. The stadium's large scoreboard still hangs behind this makeshift community. The stadium clock has stopped at 2:46 p.m., which was the moment when the earthquake cut off the electricity here and at the power plant 20 kilometers (12 miles) away. Now, the power is on again and white neon lights illuminate the rows of trailers. In one room the workers can pick up bento boxes. Next door TEPCO has built a laundromat with more than a hundred washing machines. Behind the main building in J-Village, buses are parked on the former soccer fields and debris is stored in large plastic bags on the tartan track.

Stacks of Contaminated Suits In the courtyard of the main building, TEPCO has had a small store built, where workers can purchase cigarettes and tea. Some of them, still wearing their work overalls, have gathered around a number of ashtrays and are smoking in silence. There is an Adidas advertisement glued to one of the doors and an obsolete warning sign: "No SPIKES!" An exhausted worker is asleep on the floor in the hallway.

In the window of the atrium hang huge banners for TEPCO Mareeze, the soccer team that belongs to the energy company. In the center of the building stands a panel with a large white and green map of J-Village. There was a time when this was there to help athletes find their way around. Now, a man in a TEPCO uniform stands here and uses a red felt pen to post the current radiation levels for over a dozen different places on the premises. Three TEPCO employees are sitting nearby with their laptops. The workers hand them their daily dosimeters. In return, they are given a receipt that resembles a cash register sales slip and shows the dose of radiation that they have received that day.

The government will set more stringent standards for radiation levels in food following new recommendations on the issue by the Food Safety Commission. According to the commission, health problems would emerge if accumulated radiation exposure over an individual's lifetime exceeded 100 millisieverts. Health minister Yoko Komiyama said Oct. 27 the new standards would take effect early next year and would be more strict than the temporary ones now in place. She cited the "need to secure food safety." Komiyama's announcement came on the day the commission issued its new report revising its position on health dangers from radiation contaminated food.

It revised past statements that the 100-millisievert limit included external exposure to radiation from the environment. Commission members said appraising radiation exposure from the environment was outside of their jurisdiction. The lifetime figure of 100 millisieverts is based on the assumption that radiation exposure comes only from food and does not include any external radiation exposure. The commission's recommendation will serve as the basis for new maximums for radiation levels in food from the Ministry of Health, Labor and Welfare, which are expected to be ready early next year. Health ministry officials will have to wrestle with how to incorporate health effects from external radiation exposure into the new guidelines. Parts of Fukushima Prefecture have recorded high levels of radiation following the disaster at the nuclear power plant there.

Another key issue is whether to issue different guidelines for different age groups. Children are more easily affected by radiation than adults, but there are concerns that establishing different standards for different ages will cause confusion among consumers. Health ministry officials have estimated that if individuals ate food tainted with radioactive materials from the Fukushima nuclear accident for one year, the average level of radiation exposure across all age groups would be about 0.1 millisievert. Based on that estimate, a person who lived to 100 would be exposed to about 10 millisieverts of radiation over a lifetime. The temporary food radiation standards now in place were calculated on the premise that total annual radiation exposure from food should not exceed 17 millisieverts. The temporary standards for vegetables and meat were set at 500 becquerels of radioactive cesium per kilogram. That standard was used by the farm ministry to decide if orders should be implemented to ban shipments of food products exceeding the standard. According to calculations by the International Commission on Radiological Protection, if an adult consumed 200 grams of food containing 500 becquerels of cesium-137 per kilogram every day for a year, the total annual exposure amount would be about 0.5 millisievert.

Tokyo Shinbun is a regional newspaper covering Kanto region of Japan. It has been reporting on the Fukushima accident and resultant radiation contamination in a more honest and comprehensive manner than any national newspaper. (Their only shortcoming is that their links don't seem to last for more than a week.)Their best coverage on the subject, though, is not available digitally but only in the printed version of the newspaper. But no worry, as there is always someone who transcribes the article and post it on the net for anyone to see.

In the 2nd half of the January 27 article, Tokyo Shinbun details what kind of workers are currently working at Fukushima I Nuclear Power Plant: migrant workers young (in their 20's) and not so young (in their 60's), untrained, $100 a day. Some of them cannot even read and write.

Right now, 70% of workers at the plant are migrant contract workers from all over Japan. Most of them have never worked at nuke plants before. The pay is 8000 yen to 13,000 yen [US$104 to $170] per day. Most of them are either in their 20s who are finding it difficult to land on any job, or in their 60s who have "graduated" from the previous jobs."

Beyond the police roadblocks that mark the no-go zone around the wrecked Fukushima No. 1 nuclear plant, 2-meter-tall weeds invade rice paddies and vines gone wild strangle road signs along empty streets. Takako Harada, 80, returned to an evacuated area of Iitate, a village in Fukushima Prefecture, to retrieve her car. Beside her house is an empty cattle pen, the 100 cows slaughtered on government orders after radiation from the March 11 atomic disaster saturated the area, forcing 160,000 people to move away and leaving some places uninhabitable for two decades or more. "Older folks want to return, but the young worry about radiation," said Harada, whose family ran the farm for 40 years. "I want to farm, but will we be able to sell anything?"

What is emerging six months since the nuclear meltdowns at the Tokyo Electric Power Co. plant is a radioactive zone bigger than that left by the 1945 atomic bombings at Hiroshima and Nagasaki.

While nature reclaims the 20-km no-go zone, Fukushima's ¥240 billion a year farm industry is being devastated and tourists that hiked the prefecture's mountains and surfed off its beaches have all but vanished.

The EPA re-calibrated (rigged) Japan nuclear radiation monitoring equipment causing them to report lower levels of radioactive fallout after the Fukushima nuclear meltdown than what was detected before the disaster. I recently programmed an application to pull all of the EPA radiation monitoring graphs for all major US cities and complied them into an easy to use web interface. Of course we took the data being reported with a grain of salt under the suspicion that the Feds were fiddling with the results. Now, an investigative report looking into why the much of the EPA radiation monitoring equipment was offline when the Fukushima nuclear meltdown occurred reveals that EPA has in fact rigged radiation monitoring equipment to report lower values of radiation.

RadNet – the EPA’s front-line, radiological detection network is severely flawed and suffers from maintenance and reliability issues. The lack of consistent data and the number of units offline (a techie term for broken) at the time they were most needed shows that the EPA was not prepared for this emergency. Besides that fact the broken system left us all unprotected; the confusion, apprehension and fear witnessed as people try to wade through the incomplete and inaccurate data online is evidenced by an exchange on the UC Berkely website over this RadNet graph:

The graph shows that this monitoring station was one of the units actually running on  3/11 . The readings were significantly higher prior to 3/11 and drop to a much lower level  afterwards. This is an indication that the units were running in an uncalibrated condition and were adjusted only after the events at Fukushima. Who is responsible for assuring that the system is up and running?  The EPA contracted this responsibility to a private company, Environmental Dimensions, Inc.

After scary reports came this week about large amounts of Fukushima radiation wafting over Tokyo Japan came up with the most idiotic lie about the source. The downwardly mobile BBC chimed in with this: Elevated levels of radiation found in a residential area of Tokyo are almost certainly not connected to the stricken Fukushima nuclear plant, say officials. . . . But Japan’s science minister said the radiation had been traced to material stored in the basement of a house[!!!]. Local residents had been told the radiation was no threat to health.

Umm-humm. Just some old jars of plutonium stored next to the pickled cucumber down in the ol’ basement. Such a relief! Compare that suspect story with this: Radiation in Tokyo: Over 2.7 Microsievert/Hr in Setagaya-ku on a School Route That is the air radiation. NHK News says the number happens to be much higher than the current air radiation in Iitate-mura (2.1 microsieverts/hour at the village office) in Fukushima Prefecture, where all the villagers have had to evacuate. Just like in Yokohama City, a citizen measured the air radiation, and alerted the municipal government who then went and measured. At least the municipal governments have started to at least respond. The result was 2.8 microsieverts/hour. The Setagaya-ku government power-washed the 10-meter stretch of the side walk, and the radiation came down to … (hold your breath)… 2.71 microsieverts/hour. . . . (more + MAP) http://ex-skf.blogspot.com/2011/10/radiation-in-tokyo-over-27.html

Ziggy Switkowski, former chair of ANSTO (Australian Nuclear Science and Technology Organisation) and a proponent of nuclear power for Australia, claimed "the best place to be whenever there's an earthquake is at the perimeter of a nuclear plant because they are designed so well", and then quickly added: "On the other hand, you know, if the engineers do lose control of the core, then the answer becomes different."

Strident nuclear advocate Professor Barry Brook gave assurances in his running commentary that seemed ironically prescient of what was about to happen, stating ''I don't see the ramifications of this as damaging at all to nuclear power's prospects'' and that ''it will provide a great conversation starter for talking intelligently to people about nuclear safety''.

Other arguments trotted out by pro-nuclearists about how safe nuclear power is demonstrated their chutzpah more than their good judgment. My favourite: the justification for nuclear power is that it kills fewer people than the coal industry. Ignoring the false choice this proposition entails, what does it say about the safety culture of the nuclear industry when one of its selling points is that it kills fewer people than the competition?

A leading biophysicist has cast a critical light on the government’s reassurances that Americans were never at risk from Fukushima fallout, saying “we really don’t know for sure.”

When radioactive fallout from Japan’s nuclear disaster began appearing in the United States this spring, the Obama Administration’s open-data policy obligated the government to inform the public, in some detail, what was landing here.

Covering the story, I watched the government pursue what appeared to be two strategies to minimize public alarm:

It has been 208 days since the Fukushima nuclear meltdown. The casualty count from atomic radiation is today exactly what it was the day before the Great East Japan Earthquake launched a tsunami that killed thousands and wrecked three reactors at the nuclear plant. That is, the number of radiation casualties is still zero. On May 13, sixty-three days after the quake and tsunami hit, John Boice, a professor of Radiation Epidemiology at Vanderbilt University, told a U.S. congressional committee why.

This is something that a lot of people (including me; see article) predicted on the first day of the nuclear situation. Nuclear meltdowns have never lived up to their pop-culture billing. The three major meltdowns in the history of the nuclear age—Chalk River in 1952, Three Mile Island in 1979, and of course Fukushima—resulted in zero casualties and negligible environmental damage. This is because they simply did not release enough radiation to kill anyone or harm the environment. Nevertheless, the term “nuclear meltdown” holds irresistible drawing power for media headline writers. Why is this? Because very few people understand nuclear radiation, much less its units of measure. So when faced with a barrage of reporting about radiation measurements—expressed in terms of picocuries, becquerels, rads, and microsieverts—most people have no way of evaluating that information. Therefore it all sounds kind of scary.

This may be why Dr. Boice also told the representatives this: There is a pressing need to learn more about the health consequences of radiation in humans when exposures are spread over time at low levels and not received briefly at high doses such as in atomic bomb survivors. When he gives radiation measurements, Dr. Boice oscillates between common and international (SI) units. When describing radioactivity, e.g. in bananas, he uses becquerels (SI units). When describing absorbed dose measurements, Dr. Boice uses millirems, which are common units. Most people use sieverts to describe absorbed dose. To convert millirems to microsieverts, multiply by ten. Click here for an excellent web-based radiation unit coverter.
