Iodine fission product
WebCesium and iodine, which are formed during a fission process in a nuclear reactor, are considered as major fission products responsible for the environmental burden in case of a nuclear accident. From the safety point of view, it is thus important to understand their release mechanism when overheating of the WebAnd because iodine's Z = 53, the same ratio of protons and neutrons - a democratic fission - is obtained for the total nuclear mass. 235 / 92 × 53 = 135.4. So it's most likely to …
