Radiation dose assessment for occupationally exposed workers in Malawi

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: Them...

Sumario: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 0.39µSv/hr for Mtengo wa Nthenga Hospital, 5.03µSv/hr for Bwaila Hospital and 4µSv/hr for Kamuzu Central Hospital. CONCLUSIONS: Dose levels are below the limits recommended by the International Commission on Radiological Protection (ICRP).
