The Ionising Radiation (Medical Exposure) Regulations require employers to appoint suitable medical physics experts (MPE) for nuclear medicine services, and they also define the areas where MPEs are required to provide advice and specify matters that they must contribute towards. Applications for employer licences under IR(ME)R require employers to specify the level of MPE support available and if this is provided by onsite MPEs or remotely. Assessment of these applications by the Administration of Radioactive Substances Advisory Committee (ARSAC) has highlighted variability in the levels of MPE support being provided for similar services across the UK. A working party including representatives from IPEM, ARSAC, BIR and BNMS was formed and has produced these recommendations on MPE support. Nuclear medicine services were divided into seven broad categories and MPE support for each category has been considered. However, some services that differ from the scenarios provided in this guidance may require different levels of MPE support. Positron emission tomography (PET)/CT and gamma camera imaging have been considered separately here, although it is recognised that both PET/CT and gamma cameras are often sited within the same department in many centres. The separation has been done for pragmatic purposes, as there are felt to be sufficient differences in the MPE role requirements. This guidance sets out recommendations for MPE support, and broader physics support, to run a safe nuclear medicine service and defines the responsibilities of these staff for a range of clinical nuclear medicine services. The recommendations on MPE support made are advice, but will assist employers in meeting regulatory requirements.
电离辐射（医疗照射）法规要求雇主为核医学服务任命合适的医学物理专家（MPE），并定义了 MPE 需要提供建议的领域以及他们必须做出贡献的事项。根据电离辐射（医疗照射）法规申请雇主许可证，雇主必须指定可用的 MPE 支持级别，如果是由现场 MPE 还是远程提供。放射性物质管理咨询委员会（ARSAC）对这些申请的评估突出了英国各地类似服务的 MPE 支持水平存在差异。一个由 IPEM、ARSAC、BIR 和 BNMS 的代表组成的工作组已经成立，并就 MPE 支持提出了这些建议。核医学服务被分为七个广泛的类别，并考虑了每个类别的 MPE 支持。然而，一些与本指南中提供的方案不同的服务可能需要不同水平的 MPE 支持。正电子发射断层扫描（PET）/CT 和伽马相机成像在这里被分别考虑，尽管人们认识到在许多中心，PET/CT 和伽马相机通常都位于同一个部门。之所以进行这种分离是出于实际目的，因为人们认为 MPE 角色要求存在足够的差异。本指南就运行安全核医学服务的 MPE 支持以及更广泛的物理支持提出了建议，并定义了这些工作人员在一系列临床核医学服务中的职责。所提出的 MPE 支持建议是建议，但将帮助雇主满足法规要求。
