Measurement of 60Co high gamma dose using gamma activation of 115In and 111Cd foils

Cobalt-60 gamma irradiation facilities are used in many industrial and medical applications. Gamma activation technique of 115In and 111Cd foils was used in this work to assess the performance of ethanol-chlorobenzene gamma dosimeter at high dose range of 60Co irradiation facility. Dose mapping was also performed using 115In foils. These measurements are required to control the irradiation quality and to validate dose calculations.
