Description

The objective of this study was to assess the occupational radiation dose data of the radiation workers in the radiotherapy and radiology departments for a period of two years, 2019/2020 and 202/2021. The dose reports were evaluated to identify the dose distribution of each identified sub-group, total number of monitored radiation workers, annual whole body dose (Hp(10)). The radiation workers were divided into the subgroups: Radiologists, Radiation Oncologists, Physicists, Radiographers and Radiation Therapy Technicians. The TLD system used by the hospital comprises of Harshaw 8800 Dosimetry Reader and LiF:Mg,Ti (TLD 100) dosimeters from Thermofisher Scientific. The maximum effective dose recorded was 18.05 mSv and 1.79 mSv in period 2019/2020 and 2020/2021, respectively. This is within the stipulated recommended whole body dose limit by the International Commission for Radiological Protection (ICRP).
