Abstract
A personal dose equivalent comparison was carried out between the BEV and the PTB using a direct-reading electronic dosemeter system as a transfer instrument. This was the first comparison for the `new' operational quantity, Hp(10), for individual monitoring of strongly penetrating radiation and was performed in the preparatory stage of the European co-operation for Accreditation interlaboratory comparison IR4. For the BEV-PTB comparison described in this paper, the ISO water slab phantom and the ISO radiation qualities N-60 to N-300, S-Cs and S-Co were selected, whereby the axes of the radiation fields were perpendicular to the phantom surface. The results show very good agreement. In addition, the properties of the dosemeter system were investigated.
