METHOD FOR PRODUCING ACTIVE-PART MATERIAL FOR GAMMA-RAY SOURCE

摘要

FIELD: radiochemical industry; manufacturing active-part material for cesium isotope based gamma-ray sources. ^ SUBSTANCE: proposed method involving synthesis of cesium-magnesium orthophosphate matrix of CsMgPO4 composition from dry salts of chemical agents includes production of crystal hexahydrate and heat treatment of hydrated compound at temperature ranging between 500 and 700 C. ^ EFFECT: enhanced chemical and radiation stability of ceramic matrix with respect to process scheme ruling out radioactive material loss. ^ 1 cl
