- An Alarming Change in the Status of Technetium-99 in the Vadose Zone and Aquifer at INL

Technetium-99, with half life 213,000 years, is a long lived carcinogenic radionuclide created by
nuclear fission from nuclear reactors or nuclear weapons testing. Nuclear fuel debris buried
underground at INL’s Radioactive Waste Management Complex (RWMC) and waste from
nuclear fuel reprocessing at INL’s Idaho Nuclear Technology Center (INTEC) have released Tc-
99 into the ground. Technetium-99 contamination from INTEC operations of Tc-99 has been
detected in the aquifer since 1998.
