Investigations of dosimeters with regard to their introduction into personal dose monitoring

There are only small differences between film, TL and PL dosimeters regarding the dosimetric properties checked in the annual PTB measurements, such as linearity, range, dependence of the deviation in measurement on photon energy and dependence on angle. The differences between dosimeters of a type of detector are greater than the differences between different types of detectors. Particularly in the area of small doses below 1 m Sv, it was found that the mean value of the variation coefficients for all official film GKD at 19% was nearly equal to that for all unofficial TL-GKD's at 21%. The conversion from the parameter photon equivalent dose in air to a phantom-related parameter is possible for most dosimeters. (orig./HP)
