Abstract

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.

γ辐照下磷酸镁陶瓷的辐照稳定性：氢和过氧化物的形成

摘要

MgHPO的辐射稳定性₄ ‧3H ₂ ö镁的磷酸盐陶瓷进行了研究。结果表明，从⁶⁰ Co s发出的γ辐射伴随着氢的形成。记录了微量的氧气（相对于氢气，少于1％）。在4-5 MGy的剂量下，氢的产率约为0.055±0.005分子/ 100 eV。在较大剂量下，氢的积累达到稳定水平。发现在水合水的放射分解中形成的“氧化成分”过氧化氢极有可能与镁反应生成过氧化镁MgO ₂。辐照对磷酸镁化合物的机械强度没有明显影响。
