Determination of Gross Alpha and Beta Activity from Annual Effective Dose for Dental Medical Radiation Workers

Abstract

This study determine the annual effective dose, alpha and beta activity concentration of Dental medical radiation, at Usmanu Danfodiyo University Teaching Hospital (UDUTH) Data were sourced from the facility's radiation monitoring records and analyzed to determine the annual effective doses, alpha and beta activity concentration for each worker. The findings indicate that the annual effective doses ranged from 0.61±1.28 mSv, Alpha Activity ranged from 0.031±0.064Bq and Beta Activity ranged from 0.61±1.28 Bq per worker. These exposure levels with the exception of Surgeon Assistant who recorded the highest dose of 1.0 Bq the remaining Dental workers doses were within the recommended limits set by national and international standards, which are 5 mSv per year or an average of 20 mSv over five years. Consequently, the study concludes that there is no significant radiation-related risk to any workers for annual effective dose and alpha activity concentration in the study.
