How the Map Works: A growing number of Radiation Monitoring Stations across the country, using various models of Digital GeigerCounters, upload their Radiation Count data in real time to their computer using a Data Cable, and then over the Internet to this web site, all of this accomplished through GeigerGraph for Networks software. How to Read the Map: Referring to the Map Legend at the bottom left corner of the map, locate Monitoring Stations around the country that are contributing radiation data to this map as you read this, and watch the numbers on those monitoring stations update as frequently as every minute (your browser will automatically refresh). The numbers represent radiation Counts per Minute, abbreviated CPM, and under normal conditions, quantify the level of background radiation, i.e. environmental radiation from outer space as well as from the earth's crust and air. Depending on your location within the US, your elevation or altitude, and your model of Geiger counter, this background radiation level might average anywhere from 5 to 60 CPM, and while background radiation levels are random, it would be unusual for those levels to exceed 100 CPM. Thus, the "Alert Level" for the National Radiation Map is 100 CPM, so if you see any Monitoring Stations with CPM value above 100, further indicated by an Alert symbol over those stations, it probably means that some radioactive source above and beyond background radiation is responsible.

Assemblyman Sam Blakeslee lambasted Gov. Arnold Schwarzenegger's veto of a bill that would have required three-dimensional mapping to explore earthquake fault zones near Diablo Canyon nuclear power plant. Blakeslee submitted the bill last December, a month after the so-called Shoreline Fault was discovered less than a mile offshore from Diablo. The bill would have ordered Diablo Canyon's owner, Pacific Gas and Electric Co., to use the latest high-definition technologies to map the fault, including a technique called three-dimensional geophysical reflection mapping. The state was then to use that information to make recommendations on whether seismic strengthening was needed at the plant.

If a nuclear power plant in the US were to have issues, who would be affected? In a partnership between Nature News and Columbia University, we now have a Google map that tells us the population sizes around plants so we can easily scan and see the number of people that could be affected should anything occur at the plants. The team Power Reactor Information System (PRIS) database run by the International Atomic Energy Agency (IAEA), and Columbia University's NASA Socioeconomic Data and Applications Center to map out in an easy-to-read way, the location and size of nuclear power plants as well as population numbers around those plants. On the map, population sizes are illustrated with circle size as well as color. Green circles represent less than 500,000 people and on the other side of the scale, red circles represent populations of over 20 million.

Everyone's got a notion of how the last century went, in terms of nuclear explosions. There was Hiroshima, then Nagasaki. There were some nuclear tests out in the desert, and the ocean. But would you believe there've been over 2000? In this map, which takes into account all the documented nuclear tests since 1945, two things really stand out. The few days in 1945 that saw the only use of nuclear weapons on humans register, when measured on the unfeeling scale of kilotons, as two small blips, aberrant in their location but unremarkable in their size. Then you see the key: The scale is not linear. If it was, the larger explosions would cover most of the map. That's the thing with nuclear weapons: It's easy to lose your sense of scale when it comes to how powerful they are, or what havoc they can wreak.

"Hat tip to the Map Room: a global map video of 2,053 nuclear explosions from the American desert tests in 1945 ('I am become death, the destroyer of worlds') to 1998. It is supposed to run at a rate of one second a month, but the 1945 segment is slowed down for some reason. As Jonathan Crowe points out, the pace picks up from the late "

"The Conservation Law Foundation lobbed a big curve ball into the controversy over the tritium leak at the Vernon Yankee nuclear reactor Tuesday, saying the land that is contaminated appears to be "filled" land, and thus belongs to the state. The environmental group alerted Gov. James Douglas to the problem Tuesday, saying it had done a records search at the Vernon Town Hall and discovered the potential problem. According to Chris Kilian, state director for the Conservation Law Foundation, maps showing the Vermont Yankee plant, as well as maps submitted to the Public Service Board and the Vermont Legislature, show Entergy's ownership boundary "well inland" from the banks of the Connecticut River. Kilian said the land in question, which he said was about two acres and had multiple buildings on it, was labeled "Vermont Yankee Easement Area." He said that phrase on the Entergy maps had piqued his interest, resulting in the land research down in Vernon."

Some news outlets are reporting that the meltdown was a level 4 which means it will only have local consequences. Whether this level changes remains to be seen. When this article was first posted a picture was used that turned out to be a fake. This was a clear accident and has been fixed. All information on this article is up to date and will be updated as more information comes in. SEE THIS ARTICLE - Japan nuclear fallout map - HOAX - The problem with the hoax is that the map was consistent with actual jet stream maps but was labeled as official when it was not. Multiple alternative medicine specialists have been quoted as saying that the west coast is likely to get hit.

"As part of our efforts to get readings for all of Japan, including many areas that have never had published measurements, we've been driving across the country taking readings constantly as we go. This provides some exceptionally detailed mapping of radiation levels along the routes we have traveled, we call this Safecasting. Featured Maps:"

Pacific Gas & Electric Co. says the presence of the fault was discovered using new computer programming that maps epicenters Pacific Gas & Electric Co. officials announced today that they have discovered a new earthquake fault offshore of Diablo Canyon nuclear power plant. The presence of the fault was discovered using new computer programming that allows geologists to better map the epicenters of the many small magnitude earthquakes in the area, said Lloyd Cluff, head of PG&E's earthquake risk management program, in a summary sent to the California Energy Commission earlier this week.

Rep. Jim Matheson, D-Utah, and two Idaho congressmen are calling for hearings into whether a program to compensate downwind cancer victims of atomic bomb tests in the 1950s and '60s should be expanded to include more areas - including several counties in Utah and Idaho. "Eligibility for compensation is limited to certain counties in just a few states. These geographical boundaries are, quite frankly, arbitrary boundaries that do not account for the fact that radioactive fallout does not abide by lines on a map," Matheson and Reps. Walt Minnick, D-Idaho, and Mike Simpson, R-Idaho, wrote to House Judiciary Committee leaders. The Radiation Exposure Compensation Act currently applies to residents who lived in 21 counties, including 10 in Utah - mostly in southern Utah nearest to the Nevada Test Site. However, the Deseret News obtained fallout maps in past years showing its path went through Salt Lake County and parts of eastern Utah for some tests.

Visitors at Three Mile Island are asked not to photograph guard towers, vehicle barriers and other security measures. Yet these items are easily seen on the Internet through such sites as Microsoft's maps.live.com, now bing.com/maps. Scott Portzline, a consultant for the watchdog group Three Mile Island Alert, thinks this is a security issue. He has been monitoring sites like Google Earth, which bring satellite images to home computers, for several years. But he noticed that recently the level of detail has increased. The amount of detail on Microsoft's site "could show terrorists the quickest and best route to buildings," Portzline said.

"Less than a week after concerns about earthquakes dominated public hearings on renewing Diablo Canyon nuclear power plant's operating licenses, the county Board of Supervisors on Tuesday will consider asking federal regulators to delay the process until more high-tech seismic studies can be completed. Plant owner Pacific Gas and Electric Co. has proposed doing three-dimensional mapping of the ocean floor off the nuclear power plant. Such mapping and other state-of-the-art analysis would tell geophysicists more about the earthquake potential of the area around Diablo Canyon. Supervisors will vote whether to send a letter to the California Public Utilities Commission urging the agency to approve PG&E's request to have its customers pay for the $16.73 million studies, which are expected to take three years to complete.

"The total area contaminated with radiation from the Fukushima No. 1 nuclear power plant is estimated at about 800 square kilometers, or about 40 percent the size of Tokyo, according to a radiation map created by the science ministry and U.S. Department of Energy. The report uses the same level of contamination (555,000 becquerels or higher of cesium-137) that was used to issue compulsory evacuation orders in the Chernobyl nuclear accident in 1986. To determine whether the current evacuation zone is appropriate or when residents can return home, the Nuclear Safety Commission of Japan plans to set up focal sites to heighten its monitoring of the possible further spread of radioactive contamination.

"The time series data provided by Marian Steinbech, "A Crowdsourced Japan Radiation Spreadsheet", was visualized with custom C/OpenGL software to overlay circles on geographic maps of Japan. Recent versions of the data, going back to March 1, can be downloaded from his blog here: http://www.sendung.de/japan-radiation-open-data/. These moments in time were selected to highlight how the radiation has effected Ibaraki prefecture and Tokyo, and demonstrate that while direct gamma radiation dissipates with the square distance law, particle-based radiation also dissipates with distance due to weather scattering. Although much attention has been placed on Tokyo, a very interesting finding was that Ibaraki prefecture, population 2.9 million, has received a radiation dose equivalent to nuclear worker levels while its distance from Fukushima, 100km, places it outside the current evacuation zone of 30km."
