Fission waste products
Nuclear fission is a reaction in which the nucleus of an atom splits into two or more smaller nuclei. The fission process often produces gamma photons, and releases a very large amount of energy even by the energetic standards of radioactive decay. Nuclear fission of heavy elements was discovered on Monday 19 December 1… WebDec 10, 2024 · The rest are heavy isotopes (plutonium, americium, neptunium and curium) and other fission products. Of these, Cesium-137 and strontium-90 are the most dangerous in terms of their long-term effects.
