Ridiculous. From NRC:
“ Strontium-90 and cesium-137 have half-lives of about 30 years (half the radioactivity will decay in 30 years). Plutonium-239 has a half-life of 24,000 years. High-level wastes are hazardous because they produce fatal radiation doses during short periods of direct exposure.”
Go to Hiroshima and Nagasaki. You see people. WEIRD!!!!
