FIELD: medicine. SUBSTANCE: method involves comparing concentrations of one or several mineral substances in biologically active liquid in known time intervals before and after radiation exposure. Mean square of greater concentrations ratios of every substance to smaller ones being less than 1.2, no influence is thought to be observed. The value being greater than 1.2 and less than 2.0, the exposure is estimated as one after which health state is restored in 15 min. The value being greater than 2.0, the exposure is thought to require rather long period of rest. EFFECT: provided objective conclusions. 1 tbl
