Abstract: Malawi became an IAEA member state in 2006 and developed the Atomic Energy Act and Regulations in 2011 and 2012 respectively. However, regulatory authority and personnel monitoring services have not yet been established. As such, hospitals operating radiological services in Malawi do not have personnel monitoring programme. This study aimed at developing the personnel radiation monitoring program for three hospitals in Malawi namely; Kamuzu Central Hospital, Bwaila Hospital, and Mtengo wa Nthenga Hospital. A radiation protection questionnaire was administered to the X-ray Departments involved in the study to investigate radiation protection practices in the hospitals. Dose rate measurements in the facilities were taken using survey meters and doses to individuals were recorded using personal dosimeters. The results showed that the hospitals lack radiation protection program which covers the critical issues of quality assurance and control as well as the personnel dose monitoring. Average ambient dose rate values were 0.39 μSv/hr for Mtengo wa Nthenga Hospital, 5.03 μSv/hr for Bwaila Hospital and 4 μSv/hr for Kamuzu Central Hospital. Average monthly dose for workers was 0.247 mSv. The study recommends the establishment of a regulatory authority, consistent dose assessment, quality control tests and structural shielding assessment in these and probably all the diagnostic facilities in Malawi. The personnel monitoring programme developed from this study is intended to guide diagnostic facilities and personnel monitoring service providers in Malawi in tracking and reporting exposure record for their occupationally exposed workers.
