it's stored in the testiticle, t too. so it's s a ubiquitous, really dangerous isotope, and from the time they discovered it in the manhattan project, they knew its dangers. >> does plutonium come only from nuclear weapons testing, or is there a risk of it escaping from nuclearar power plants asas wel? >>>> it's nnot emitted by powerr plants roroutinely. routinely, power plants emit radioactive elements all the time. tritium-- they y cannot prevent tritium escapingng--highly carcinogenic. it's--hydrogen--radioactive hydrogen, h3, highly carcinogenic. that's probably what's causing the cancer in the kids living around the reactors in germany. carbon-14, highly carcinogenic. xenon, krypton, argon are all emitted, and they say, "oh, it's just routine," like i could say, " "oh, you've justst got a routine cancer, d't worry about it." that sort of thingng. plutonium doesn't escae until thehere is an accident lie a meltdown or an explosion like fukushima or chernonobyl. t thre mile island had a meltdown. i remember when i first
