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

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