In 1990, an intercomparison programme for personnel dosimetry services was developed and carried out by the National Institute of Public Health and Environmental Protection. Six services participated in this first national intercomparison in the Netherlands, all using TLD systems. In addition, one service also participated with a film badge system. The dosemeters were irradiated with photons on the surface of a 30 cm diameter sphere of polymethylmethacrylate (PMMA). The range of the mean photon energy was 48 keV to 1250 keV. The range of the doses was 0.055 mSv to 12.3 mSv. All services were able to reproduce doses larger than 0.2 mSv within -33% and +50%. For doses smaller than 0.2 mSv all services using TLD systems were able to reproduce the conventional true value within +- 100%.
