WebApr 13, 2024 · The danger of indiscriminately releasing nuclear fission products into the ocean is that the products can find their way into the food chain. Once in the food chain the nuclear fission heavy nuclei like cesium-137, strontium-90 and iodine-131 tend to concentrate in human muscle, bones, and thyroid. Cancers can be the result. WebThe binding energy is the energy which is used to hold a nucleus together. 2.) Nuclear fusion is possible for only fusion of lighter nuclei but not for heavier ones, because the binding energy per nucleon is more for lighter nuclei. 3.) The binding energy is increased; holding of nucleons takes place. how is food heated in a microwaveWebNuclear fission is a nuclear reaction or a decay process, in which the heavy nucleus splits into smaller parts (lighter nuclei).
