During the 1949 Green Run Test at Hanford, Washington, the military and the Atomic Energy Commission released a radioactive cloud that spread out over southeast Washington and Oregon. The details of these tests have been shrouded in secrecy over the years. This fact sheet provides information on the Green Run Test as well as 12 other radioactive releases at three other nuclear sites--Oak Ridge, Tennessee, Dugway, Utah, and Los Alamos, New Mexico--between 1948 and 1952. During two of tests at the Los Alamos site, for example, atmospheric radiation reached small towns 70 miles away. The potential health consequences of these experiments are still under study. https://www.govinfo.gov/content/pkg/GAOREPORTS-RCED-94-51FS/html/GAOREPORTS-RCED-94-51FS.htm GAO/RCED-94-51FS https://www.govinfo.gov/app/details/GAOREPORTS-RCED-94-51FS Fact Sheet GAO/RCED-94-51FS; Nuclear Health and Safety: Examples of Post World War II Radiation Releases at U.S. Nuclear Sites; Nuclear facility safety Nuclear radiation monitoring Radiation safety Nuclear weapons testing Atomic energy defense activities Munitions Weapons research Radiation accidents Radiation exposure hazards Safety standards AEC Green Run Test Dugway (UT) Operation Crossroads Nuclear Test Air Force Operation Sandstone Nuclear Test Air Force Operation Fitzwilliam C-47 Aircraft B-17 Aircraft Armed Forces Special Weapons Project Washington Oregon
