Assessment of Radiation Dose from CT to Workers and Public from Common Diagnostic Investigations in Qatif Hospital

In general, the exposure to ionizing radiation, whether accidental, occupational or medical leads to harmful biological consequences like death or the initiation of cancer formation. The aim of the research project is to evaluate the radiation dose from computed tomography (CT) to workers and public from common diagnostic investigation in Qatif hospital. Also the annual effective doses due to diagnostic investigations will be calculated and compared with maximum permissible of the world recommended limits. And finally to create interest and increase the radiation workers and public awareness about the ionizing radiation hazard from CT particularly due to repeated scans. In this work the measured annual absorbed dose of 8.010.51mSv and 3.070.15mSv at the control area was found to be received by operators working in Qatif central hospital (Phillips ICT-128 slices) and Qatif central hospital (Somatom Definition AS-64 slices) respectively. The public in these hospital was found to expose to annual doses of 2.290.09mSv and 1.410.09mSv from Qatif central hospital (Somatom Definition AS-64 slices), and Qatif central hospital (Phillips ICT-128 slices) respectively. Although there are some slightly differences in our measurements in comparison of these hospital, all the findings are within the allowable recommended limits of annual absorbed dose from the ionizing radiation by the international cooperation of radiation protection (ICRP).
