Abstract

Radiation exposure poses hazards for health-care workers, patients and health-care facilities(HCFs). Radiographic imaging is among the diagnostic tools in medicine that has an extremely valuable and accuracy, hence, ionizing radiation and computed tomography (CT) scan has potential risks. Hospital workers in the x-ray machine rooms are likely to get exposed to the excess of radiations. Therefore, Personnel and radiation safety monitoring is a necessary safety precaution in the radiography. The aimed of this study is to assess the occupational radiation exposure and safety protection among medical staff in HCFs in hospitals In Dhaka Bangladesh. Total of five (5) HCFs with radiological services was selected during the data collection in the period from April to September 2015. The radiation assessment survey was carried out by the measurement of radiation in the CT-scan room and x-ray at different points of the imaging, diagnostics, and waiting rooms of the five hospitals. The radiation safety was assessed by monitoring the eighty (80) occupational workers from five hospitals In Dhaka Bangladesh for six months to quantify their exposure to excess radiation doses using a stance potable radiation dosimeter. Data revealed that the average estimated dose for all subjects ranged from 0.01 to 2.42 mSv. Among these workers, workers in radiology department received the most substantial estimated dose, which is below recommended dose for the international dose limit (20 mSv). It is significant to comment that workers were wearing protective lead aprons and thyroid shields when performing examinations, in agreeing to the radiation protection policy.
