Abstract
This study aimed to produce a personal dosimeter to connect the electronic devices to transfer the dosimetry data online including dose rate data and integral dose. At first, an electronic board was designed. Afterwards, the board was simulated using Altium Designer software. Then, the microcontroller programming was performed using Code Vision software. The performance of the elements was tested using Proteus Design Suite software and the circuit diagnosis and testing were practically implemented. Afterwards, the calibration factor and the count-to-dose conversion coefficient were obtained using an ionization chamber in the Secondary Standard Dosimetry Laboratory of Iran. Furthermore, dose distribution as a function of distance to the source, was obtained using the produced dosimeter and was compared using a calibrated ionization chamber. To this purpose, an unmitigated Cs-137 source, a Cs-137 source with a 22 mm Pb shield, and a Cs-137 source with a 22 mm plus 18 mm shield were used. The results showed a calibration factor of 0.99 ± 0.02 for the designed dosimeter. Calibration results showed that the produced dosimeter passed the ISO/IEC 17025:2005 criteria. Furthermore, the dose distribution results demonstrated negligible differences of less than 0.01% between the produced dosimeter and the reference ionization chamber. It was concluded that the produced dosimeter could be used as a reference and standard dosimeter in laboratories, for monitoring and dosimetry of ionizing photon radiations.
