While working with cyclotrons used for the production of radiopharmaceuticals, workers can experience significant exposure to the adverse effects of ionizing radiation. The aim of this paper was to determine the typical level of such exposure received by such personnel while servicing cyclotrons.
Exposure was assessed using TLD detectors placed in an anthropomorphic phantom, as well as dose meter to determine whole body and eye lens exposure. The phantom was placed in locations receiving the greatest exposure to ionizing radiation during service activities. The time spent by employees during servicing was assessed based on routine visits by service technicians. The obtained results were compared with readings of detectors worn by employees during service activities.
The highest equivalent doses in the thoracic area were found to be received by the lungs (211.16 μSv/year). In the head and neck area, the highest dose was measured in the eye lens (3410 μSv/year). The effective dose for the whole body was found to be 1154.4 μSv/year, based on the phantom, and 149 μSv per service visit (1192 μSv/year), based on the dose meters carried by the workers.
Service workers are exposed to significant doses of ionizing radiation, representing a clear radiological protection issue. To reduce exposure to eye lenses, it is recommended to use protective goggles when working with highly-radioactive elements. Int J Occup Med Environ Health. 2022;35(6):753-60.
在使用回旋加速器生产放射性药物的过程中，工作人员可能会受到电离辐射的不良影响。本文旨在确定服务回旋加速器的人员所受到的此类辐射的典型水平。
使用放置在人体模型中的 TLD 探测器以及剂量计来评估暴露情况，以确定全身和晶状体的暴露情况。人体模型被放置在服务活动中接受最大电离辐射的位置。根据服务技术人员的例行访问来评估员工在服务过程中花费的时间。将获得的结果与员工在服务活动中佩戴的探测器读数进行比较。
在胸部区域，肺部接收到的等效剂量最高（211.16 μSv/年）。在头部和颈部区域，晶状体接收到的剂量最高（3410 μSv/年）。根据人体模型，全身有效剂量为 1154.4 μSv/年，根据工作人员携带的剂量计，每次服务访问为 149 μSv（1192 μSv/年）。
服务人员受到显著剂量的电离辐射，这是一个明显的放射防护问题。为了减少晶状体的暴露，建议在处理高放射性元素时使用防护眼罩。国际职业医学与环境卫生杂志。2022；35(6):753-60.
