FIELD: radiochemical industry, cesium isotope based gamma-ray sources.
SUBSTANCE: method is proposed for synthesizing ceramic matrix of CsMgPO4 composition from aqueous or acid solutions using process scheme ruling out loss of radioactive material. Mixture of solutions is concentrated by evaporation and solid residue is subjected to step-by-step heat treatment at temperatures of 500 to 550 °C and 600 to 700 °C.
EFFECT: enhanced chemical and radiation stability of cesium-magnesium orthophosphate matrix.
