Is iodine 131 stable
WitrynaIodine-131 is found in the gaseous and liquid waste streams of nuclear power plants, but is not released to the environment during normal reactor operations. Is Iodine 131 stable or unstable? Iodine is a metal found throughout the environment in a stable form, iodine-127, and as unstable radioactive isotopes of iodine. WitrynaMost I-131 distributes over large distances, typically with only 10% making its way to the earth's surface before undergoing spontaneous radioactive decay to stable xenon-131. Radioactive iodine is difficult to obtain in quantity and is not considered a likely isotope for use in a Radiological Dispersal Device (RDD).
