Abstract
Herein, we analyze the dose distribution and factors influencing the occupational internal irradiation exposure to iodine-131 (131I) for nuclear-medicine staff in Jiangsu Province. A total of 472 individuals in 56 hospitals were monitored during the three-year monitoring period, and 131I was detected in 170 of them. The highest thyroid activity level detected across all cases was 24.83 kBq, with the average thyroid activity being 130.3 Bq. The average annual dose of irradiated staff members was 0.339 mSv. The primary factors related to the detection rate of 131I in the irradiated staff members were their work position, their location, the operation of an automatic dispenser, and their weekly working hours. Internal exposure thus requires due attention, and further effective monitoring of internal exposure should be conducted for all such staff members.
期刊介绍：
Radiation Protection Dosimetry covers all aspects of personal and environmental dosimetry and monitoring, for both ionising and non-ionising radiations. This includes biological aspects, physical concepts, biophysical dosimetry, external and internal personal dosimetry and monitoring, environmental and workplace monitoring, accident dosimetry, and dosimetry related to the protection of patients. Particular emphasis is placed on papers covering the fundamentals of dosimetry; units, radiation quantities and conversion factors. Papers covering archaeological dating are included only if the fundamental measurement method or technique, such as thermoluminescence, has direct application to personal dosimetry measurements. Papers covering the dosimetric aspects of radon or other naturally occurring radioactive materials and low level radiation are included. Animal experiments and ecological sample measurements are not included unless there is a significant relevant content reason.
