Testing of a thermoluminescent personal dosimeter at interim storages for spent nuclear fuel

The National Radiation Protection Institute in Prague is about to use a commercially available multi-element whole-body thermoluminescence dosimeter for its radiation personnel. During the phase of practical verification of the method, the dosimeter was tested, among others, in mixed neutron-photon fields in the area of interim storages for spent nuclear fuel of the Czech nuclear power plant Dukovany. The testing was made with the intention to get information about accuracy of H(p)(10) determination for cases when no site-specific calibration is available or neutron spectra are not known. The measured photon and neutron personal dose equivalents were evaluated and discussed in relation to results obtained by survey meters and neutron spectra measured before.
