Preliminary Staff Dose Assessment for Common Fluoroscopy Guided Procedures at Korle-Bu Teaching Hospital, Accra, Ghana

Abstract

Preliminary studies on effective and eye lens doses of six Radiologists, four Cardiologists have been conducted for a period of 3 months. Electronic dosemeters positioned under and over lead apron of staff were used for the dosimetry. The estimated effective dose per month to Cardiologist and Radiologist were 0.01–0.07 mSv and 0.03–0.14 mSv, respectively. The estimated eye lens doses per month to Cardiologists and Radiologists were also 0.15–0.30 mSv and 0.53–3.39 mSv, respectively. The effective doses per month to staff were below the ICRP acceptable limit of 1.67 mSv/month but the upper limit of the range of estimated eye lens dose exceeded the ICRP acceptable limit by a factor of 2. Regular use of protective goggles and consistent eye lens dose monitoring is encouraged at the hospital for dose optimization.
