Incorporation measurements in Switzerland: the approved dosimetry service at PSI

The swiss radiation protection regulation requires approval of external and internal dosimetry laboratories. The ordinance on individual monitoring specifies the terms of approval, the survey methods and the standard interpretation to assess the committed effective dose. Specific information is given for 25 radionuclides concerning metabolism, methods of measurement, survey interval and interpretation of the results. On successful completion of a technical audit by an external expert, the dosimetry service of PSI has been approved for internal dosimetry by the swiss authorities by January 1th, 2001. The scope of approval includes 5 different measuring methods for 30 radionuclides. (orig.)
