The diffusion coefficients for /sup 90/Sr and /sup 134/Cs are less by about four orders of magnitude than those for /sup 22/Na at temperatures close to the transformation points in these glasses. At comparable temperatures, the strontium and cesium radionuclides migrate 30-700 times more rapidly in aluminophosphate glasses than in aluminoborosilicate ones. Crystallization in an aluminophosphate glass increases the diffusion mobilities of /sup 90/Sr and /sup 134/Cs and reduces that of /sup 22/Na. Gamma irradiation of aluminophosphate and aluminoborosilicate glasses has no appreciable effect on the diffusion of /sup 22/Na.
