Kegunaan isotop iodin
- Natural cosmogenic 129I enters groundwater and other terrestrial environments from the atmosphere and then decays to 129Xe. The isotope-amount ratio n(129I)/n(127I) can be used as a clock to estimate time since cosmogenic 129I entered the system. The amount of product 129Xe in such cases is too small to measure; however, excess quantities of 129Xe can be found in meteorites and other very old samples that contained extinct primordial 129I. Younger water bodies also can be differentiated from older water bodies by determining the amount of anthropogenic 129I released since the 1960s from sources such as nuclear bomb tests,.
