Radioiodine gas
TīmeklisRadon is a radioactive noble gas. Of all radon isotopes only two, radon-222 (radon) and radon-220 (thoron) occur in significant amounts indoors. Radon-222 is one of the decay products of uranium-238 (half-life 4.5 × 109 years) and radon-220, a nuclide thorium-232 decay (half-life 1.4 × 1010 years). The mother nuclides are radium-226 … TīmeklisThe management of radioiodine and prevention of its release to the environment is paramount in the nuclear industry. This includes release of radioiodine during used nuclear fuel reprocessing or other nuclear technology, the release during nuclear accidents and in the management of legacy wastes.
