The assessment of occupationally exposed medical radiation workers at the Institute of Nuclear Medicine and Oncology (INMOL), Pakistan has been perfomed. The whole-body radiation exposure doses of 120 workers in nuclear medicine (NM), radiotherapy (RT) and diagnostic radiology (DR) were measured by using the film badge dosimetry technique for the time interval (2007-11) and their results presented. The annual average effective doses in NM, RT and DR were found to be well below the permissible annual limit of 20 mSv (averaged over a period of 5 consecutive y). The declining trend observed in the annual average dose values during the time interval (2007-11) is an indication of ameliorated radiation protection practices at INMOL, Pakistan.
