Abstrakt:	Radiation stability of MgHPO4‧3H2O magnesium-phosphate ceramic was studied. It was shown that the effect of γ-radiation from 60Co s accompanied by the formation of hydrogen. Oxygen is recorded in trace amounts (less than 1% relative to hydrogen). At a dose of 4–5 MGy, the yield of hydrogen is approximately 0.055 ± 0.005 molecule/100 eV. At larger doses, the accumulation of hydrogen reaches the stationary level. It was found that the "oxidizing component," hydrogen peroxide, formed in the radiolysis of hydrate water reacts in all probability with magnesium to give magnesium peroxide, MgO2. The irradiation has no noticeable effect on the mechanical strength of the magnesium-phosphate compound. [ABSTRACT FROM AUTHOR]
