Determination of A Correction Factor for Measurement of Occupational Dose from Beta Source Using InLight®nanoDot OSL
Keywords:
InLight®nanoDot OSL, personal dosimeterAbstract
An occupational radiation worker must have a personal dosimeter to monitor occupational exposure dose. InLight®nanoDot OSL, is the dosimeter used for detection of exposure at a specific position of the body. Accurate determination of occupational dose of exposure from beta sources needs a correction factor for energy. This study was conducted to obtain the correction factor essential for InLight®nanoDot OSL after exposure to Sr-90, the beta source, at 0, 5, 10, 15 and 20 millisievert (mSv). The correction factor was shown to be 2.90 with differences ranging from 0.20% to 2.93%. Using the correction obtained, the amount of beta radiation measured was closed to that radiated from the Sr-90 source. Our study suggested that determination of the correction factor is necessary prior to performing a service on measurement of occupational dose from beta sources using InLight®nanoDot OSL.
