摘要：
The radiation resistance of epoxy compounds, solidified by crystalline hardening agents - metaphenylenediamine and phthalic anhydride - is investigated. It is shown that under conditions of gamma irradiation (E = 1.33 MeV) the temperature of vitrification of the compounds depends oil the dose (doses up to 1500 Mrad were investigated) and temperature 20-160 degrees C, and the radiation gas release depends oil the vitrification temperature and irradiation. It is shown that epoxy-phthalic anhydride compound is best as a matrix for immobilizing solid radioactive wastes at high temperatures (80-130 degrees C). The experiments showed that the proposed compound call be recommended for immobilizing solid radioactive wastes.
