It took only 200 billionths of a gram, of polonium 210, do this to Alexander litvinenko. It took him days to die and it degraded most of his organ system - Poisoning

IT was injected. It took only 3 millionths of a gram of powdered plutonium, to give 7 dogs lung cancer within a week of lung exposure at Los Alamos plutonium pit factory, by Santa Fe new mexico 20 lbs of nuclear waste just extracted from the core of a nuclear reactor, will irradiate you to death in 10 minutes if you are within 15 feet of it . It has occurred on several occasions. In reactor refueling Billionths of a gram of Californium can destroy your bone marrow, in a matter of minutes 15 grams of cesium 137 , iridium 110 , or cobalt 60 used in radiography boxes to image, ship hull welding seams, can kill a diver instantly. They can irradiate you to death if you are within, 5 feet of it 50 feet under water. This has happened at least 10 different times to divers, using radionuclide boxes to scan welding seams underwater for cracks. It takes only 50 billionths of a gram of I131 used for thyroid ablation, to kill you quickly A minute amount of dissolved and injested Pure radium or uranium 235 will kill a person in a day. Any concentrated radionuclide exposure or irradiation, has long lasting effects. Think of the many cancer patients that received radiation therapy and had to have bone marrow transplants to survive.

There have been two nuclear accidents at Tokaimura, facility at Tōkai, Ibaraki, Japan: On 11 March 1997, an explosion occurred in a Dōnen plant, and on 30 September 1999, a serious criticality accident happened in a JCO plant. Regarding the Tokaimura nuclear plant nuclear accidents, the first accident occurred on 11 March 1997 producing an explosion after improperly heated nuclear waste products caught on fire at the Dōnen plant. Over twenty people were exposed to radiation all but 5 of them are dead. The second incident on 30 September 1999 happened at the JCO plant. It was classified a serious criticality accident. The incident resulted in radiation exposure for 667 people , half of which since died or had serious health problems. Two workers died immediately.
