Abstract
Mice were exposed to 900 R of gamma radiation and /sup 22/Na was injected intraperitoneally into irradiated as well as unirradiated control mice. The concentration of /sup 22/Na in blood, liver, and spleen was assayed. Results showed that following exposure to radiation there were changes in ion permeability of membranes manifested by accumulation of /sup 22/Na in organs. It is suggested that the change in ion permeability may serve as a criterion of radiation injury to cell membranes. (HLW)
