ABSTRACT
Objective: The objective of this study is to assess, analyse and discuss the occupational exposure to ionizing radiation in interventional cardiology practices in Bangladesh for the last 5-year periods.
Method: Each

For the 5-year periods, no occupational workers were found to have received an effective dose >50 mSv in a single year or >100 mSv in a consecutive 5-year periods. Therefore, occupational exposures to ionizing radiation of all workers in interventional cardiology practices are lower than the prescribed dose limit recommended by International Organizations. However, very few workers individual effective doses are higher than recommended average annual dose limit (20 mSv.y-1). Therefore, occupational workers in interventional cardiology practices should pay more attention on radiation protection procedures and guidelines to keep the doses below the annual average dose limit other than the maximum allowable dose limit in a year. The status and trends in occupational exposure demonstrate that radiation protection conditions at the majority of workplace were adequate. Despite that, further optimization is necessary due to large variations observed in the maximum individual doses over the 5 year …show more content…
