This report is experiments directed toward to establish the tool for quantitative radiation analysis using the electron spin resonance (ESR) technique. As basis research, stable free-radicals generated in calcium salt or cement powder by high dose -ray irradiation were measured with ESR equipment. Stable free-radicals generated in the several samples by -ray irradiation. Their sigmnal behaviour was experimentally investigated as a function of dose with rays. The stability of the ESR signal of the free radical after irradiation was investigated.
