ADAPTIVE RESPONSE TO HIGH-LET RADIATION INDUCED BY COBALTN.N. HOURELD, J.V. HIND, J.P.S. SLABBERT AND H. ABRAHAMSE
The purpose of the study was to induce an adaptive response in radiation exposed and unexposed individuals as measured by the frequency of micronuclei. Lymphocytes isolated from 5 healthy donors were exposed to an adapting dose of 0.1 Gy CO" and a challenging dose of either 1.5 Gy C06° or 0.8 Gy neutron beams. An adaptive response to both the neutrons and cobalt was seen in three of the five individuals. An adapting dose of C06° is able to protect cells from a challenging dose of neutron radiation.
