WebFission product 131 I (T 1/2 = 8.02 days) is a very important radionuclide in view of radiation protection because it can be released from various nuclear installations and its volatility makes it highly mobile in the environment. Because of its relatively high bioavailability, it readily enters the biosphere and propagates through the food chain. Milk … WebHigh-level waste is full of highly radioactive fission products, most of which are relatively short-lived. This is a concern since if the waste is stored, perhaps in deep geological storage, over many years the fission products decay, decreasing the radioactivity of the waste and making the plutonium easier to access. The undesirable ...
