A computer-controlled multisource gamma ( 60 Co, 137 Co, and 241 Am) irradiation system has been developed indigenously for the purpose of strengthening the quality assurance program of individual monitoring service in India. The system can be used for the irradiation of personnel dosimeters both in panoramic and collimated modes in a well-reproduced geometry. Measurements of output (air-kerma rate) of the sources in both collimated and panoramic modes and transit dose were carried out. The study also includes radiation protection survey of the installation. Depending upon the distance from the source, the Monte Carlo-calculated air-kerma rates of the 60 Co and 137 Cs sources compare within 5-10% against measurements. In the collimated mode, the calculated beam uniformity is within 3% in the area of 20 cm × 20 cm centered on the collimator axis. |
