The Energy Daily: Ten-Year Probe Offers First View Of Los Alamos Releases - 0 views

Energy Net on 19 Sep 09After 10 years of sifting through thousands of pages of classified records and overcoming secrecy obstacles at the nuclear weapons lab, independent investigators have provided the first rough estimates of radioactive and toxic releases from Los Alamos National Laboratory dating back to its earliest operations and the potential health impact of the nation's first atomic bomb blast on ranchers and other nearby residents in New Mexico. Investigators for the Los Alamos Historical Document Retrieval and Assessment (LAHDRA) project released a draft final report in late June that-while far from definitive in its conclusions-said there was persuasive evidence from spotty, decades-old emissions monitoring data that radioactive releases during Los Alamos' early years were so significant that they could dwarf the cumulative releases from all of the Energy Department's other early nuclear weapons production sites. In particular, the researchers said that although the lab did not monitor emissions from many of its earliest plutonium processing facilities, fragmentary records-especially "industrial hygiene," or worker safety, reports from 1955 and 1956-suggest plutonium releases in the late 1940s and early 1950s were much higher than has been acknowledged by the government to date.
