Zinc-65, hitherto found in cyclotron workers and in other specialized populations, has now been detected in a group of reactor workers. While the highest levels detected are less than 0.2 percent of the maximum permissible concentration, the movement of this neutron-induced radionuclide is of interest, and the baseline information is important for future studies.
