Abstract
The induced γ-radioactivity brings the main contribution to the exposure dose for the personnel of a high-energy accelerator. At the machines accelerating the heavy particles to the energies of ⩾1 GeV/nucleon, this contribution amounts up to 50% of the dose. The present study deals with the levels of induced radioactivity in dependence on the target material, sort of particles being accelerated, and time t elapsed since the end of irradiation. Recommendations are given to evaluate the rate per an incident nucleus dA(t) of a dose caused by the induced radioactivity of a thick target, from the dose rate dP(t) of protons with the same ratio of energy on nucleon
