Background The objective of this study was to assess individual doses received by radiographers, and the scattered radiation dose rate reaching the control panel in X-ray departments of three hospitals in Malawi, in-order to compare them against the internationally recommended limits. Methods Themoluminescent Dosimeters were issued to fifteen (15) radiographers to record their dose for a month. Dose rate measurements were recorded using survey meters. Results Average monthly dose for workers was 0.247mSv. Average ambient dose rate values were 0.39 mu Sv/hr for Mtengo wa Nthenga Hospital, 5.03 mu Sv/hr for Bwaila Hospital and 4 mu Sv/hr for Kamuzu Central Hospital. Conclusions Dose levels are below the limits recommended by the International Commission on Radiological Protection (ICRP).
