AN INTERCOMPARISON STUDY OF THERMOLUMINESCENT DOSEMETERS FOR ENVIRONMENTAL MEASUREMENTS
The importance of the relatively large contribution to human exposure levels made by natural radiation has long been recognized. However, quantitative studies of natural radiation levels have been limited because of the lack of availability of suitable passive integrating dosemeters. The development of thermoluminescence and etched track dose measurement techniques have led to a renewed interest in carrying out such studies. Similarly thermoluminescent dosemeters are now routinely used to monitor exposure on or around nuclear sites. In the UK, the NRPB has a continuing interest in the development of thermoluminescence measurement techniques and is currently using thermoluminescent dosemeters for the measurement of environmental gamma ray exposure in houses as part of a national indoor radiation survey. A number of other scientific laboratories are currently involved in similar studies. Five such laboratories were invited to participate in an intercomparison study of the performance of thermoluminescent dosemeters for environmental measurements. Following completion of this exercise a further five laboratories were invited to participate in a second study. The objectives of the intercomparison were: (1) to provide the participants with the opportunity to have their dosemeters exposed at various and different sites; (2) to enable a quantitative comparison of different types of thermoluminescent phosphors, designs of dosemeters, and systems; (3) to establish a forum for the discussion of topics of mutual interest in the field of environmental gamma dosimetry.
