This paper aims to determine the levels of exposure to neutron and photon radiation among the personnel engaged in cyclotron operation and the personnel engaged in the production of radiopharmaceuticals, with the use of the environmental radiation monitoring system (RMS) installed in the positron emission tomography laboratory. The annual exposures of employees operating the cyclotron measured with the use of the RMS system are: 1.39 ± 0.16 mSv in case of photon radiation and 2.61 ± 0.14 mSv in case of neutron radiation. In the case of employees in the radiopharmaceuticals' production zone, the annual exposures measured by means of the RMS system are 0.15 ± 0.03 mSv in case of photon radiation and 0.11 ± 0.01 mSv in case of neutron radiation. The exposure levels among the personnel engaged in cyclotron operation and the personnel engaged in the production of radiopharmaceuticals are below the permissible radiation dose limits.

根据辐射监测系统，从事回旋加速器操作的人员和从事放射性药物生产的人员的电离辐射暴露水平。

本文旨在利用正电子发射断层扫描实验室安装的环境辐射监测系统（RMS），确定从事回旋加速器操作的人员和从事放射性药物生产的人员的中子和光子辐射暴露水平。 . 使用 RMS 系统测量的操作回旋加速器的员工的年暴露量是：在光子辐射的情况下为 1.39 ± 0.16 mSv，在中子辐射的情况下为 2.61 ± 0.14 mSv。对于放射性药物生产区的员工，通过 RMS 系统测量的年暴露量在光子辐射情况下为 0.15 ± 0.03 mSv，在中子辐射情况下为 0.11 ± 0.01 mSv。
