根据瑞士关于放射防护的立法，Paul Scherrer研究所（PSI）提供经瑞士联邦核安全监察局批准的剂量测定服务。1997年，放射量测定服务还获得了瑞士联邦计量和认证办公室的认证，成为根据EN 45004进行法律的个人和环境放射量测定的检查机构。核证范围包括通过热释光和固态径迹探测技术确定光子、中子和β辐射的个人剂量当量以及光子和中子辐射的环境剂量当量。在这一正式认证中，确认也符合ISO 9002的相关要求。第一次重新认证将于2001年进行，目前正在努力实现从EN 45004到ISO 17025的过渡。认可是在剂量测定领域实现协调一致的一种可行、切实可行和可接受的方式。然而，在开始正式认证之前，应进行认真的分析，不仅要考虑到成本效益方面，还要考虑到国家法律的要求。
In compliance with the Swiss legislation on radiological protection, the Paul Scherrer Institute (PSI) operates a dosimetry service that is approved by the Swiss Federal Nuclear Safety Inspectorate. In 1997, the dosimetry service was also accredited by the Swiss Federal Office of Metrology and Accreditation as an inspection body for legal personal and environmental dosimetry, according to EN 45004. The accreditation covers determination of personal dose equivalent for photon, neutron and beta radiation, and ambient dose equivalent for photon and neutron radiation, by means of thermoluminescence and solid state track detection techniques. Within this formal accreditation it was confirmed that the relevant requirements of ISO 9002 are also fulfilled. The first re-accreditation will take place in 2001 and work is going on to achieve the transition from EN 45004 to ISO 17025. Accreditation is a feasible, practicable and acceptable way to achieve harmonisation in the field of dosimetry. However, before starting on the path to formal accreditation, a careful analysis should be made, taking into consideration not only cost-benefit aspects but also national legal requirements.
