Occupational radiation monitoring and quality assurance in hospital X-ray departments

RESUMO

Quality assurance is essential to any programme of diagnostic radiology; to prevent undue exposure of x-ray personnel and patients to radiation. This paper reports observations from a survey of some hospital x-ray facilities in Accra and Kumasi in Ghana; to find out about steps taken by x-ray workers to ensure quality control and administration in diagnostic radiology. The grid point method has been used to do a detailed study of scatter radiation levels of two x-ray departments in Accra. The iso-dose rate contours have been analysed; and results show the importance of good design of x-ray rooms and provision of protective structures
