WebRadioiodine. Radioiodine, iodine-131, is an important radioisotope of iodine. Radioiodine plays a major role as a radioactive isotope present in nuclear fission products. It is a major contributor to health hazards when released into the atmosphere during an accident. Iodine-131 has a half-life of 8.02 days. 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 … Web11 apr. 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. development human wealth
