Abstract
Radiation is energy that travels through space or matter in the form of a particle (alpha and beta) or wave (Xrays and gamma rays). X-ray transfers a certain amount of energy, which is dangerous, when interacts with the biological system. Recently, great attention has been paid to monitor and estimate the dose limits of public exposure to X-ray in order to be able to provide an appropriate protection of patients/workers. This study aimed to assess the exposures of the workers to X-ray through measuring (using Radiation Alert Monitor “4”) and sampling (using questionnaires) the X-ray within and outside the Radiology Unit, University of Maiduguri Teaching Hospital (UMTH). The result showed that the average radiation dose around Radiology Unit as 0.0225 mSv/y. This is negligible when compared with an effective dose equivalent 50 mSv/y for whole-body exposure recommended by International Commission on Radiation Protection and National Council on Radiological Protection recommendations. This implies that the radiation workers at the Radiology Unit were not at any risk of radiation related ailments because of their work. Questionnaire based on the Code of Practice of X-ray Radiation Workers were also administered to senior staff in the Unit. The information obtained revealed that not all the necessary radiation safety regulations were in practice in the Unit. Hence, the need for radiation safety checks in place. The results obtained from this study could be helpful in prevent the risks of radiation exposures that may involve workers in radiology unit.
