초록
Radiation workers in nuclear medicine use radioisotopes for diagnostic evaluation and treatment, so Their risk of radiation exposure of the lens is greater than for other medical staff. Furthermore, the ICRP report 118 has suggested to reduce the occupational equivalent dose limit for the lens from 150 mSv·year-1 to 20 mSv in a year, averaged over defined periods of 5 years, with no single year exceeding 50 mSv. Therefore, the radiation worker in nuclear medicine may have risk to exceed the equivalent dose limit of the lens. To evaluate the performance of the shield for lens protection, the dose of the lens was measured using an ED3 electron dosimeter. During administration of the radiopharmaceuticals, lens dose was measured in non-shielding and with syringe shield, lead glass, and L-block. Also, based on the measured doses, Calculated the dose per 1 mCi of used radioisotope to help make the work plan. Additionally, compared the measurements of the OSL and ED3 over 6 month period to evaluate whether the lens dose of OSL could replace the ED3 measurements.
Abstract
Radiation workers in nuclear medicine use radioisotopes for diagnostic evaluation and treatment, so Their risk of radiation exposure of the lens is greater than for other medical staff. Furthermore, the ICRP report 118 has suggested to reduce the occupational equivalent dose limit for the lens from 150 mSv·year-1 to 20 mSv in a year, averaged over defined periods of 5 years, with no single year exceeding 50 mSv. Therefore, the radiation worker in nuclear medicine may have risk to exceed the equivalent dose limit of the lens. To evaluate the performance of the shield for lens protection, the dose of the lens was measured using an ED3 electron dosimeter. During administration of the radiopharmaceuticals, lens dose was measured in non-shielding and with syringe shield, lead glass, and L-block. Also, based on the measured doses, Calculated the dose per 1 mCi of used radioisotope to help make the work plan.
