Abstract

This work evaluated the Hp(10)dose for the personnel exposed in mixed field inside several locations of reactor 1 building at Cernavoda NPP. In order to achieve this we used active (EPD N2 and DMC 2000GN) and passive (TLD 8806) personnel dosimeters and one ambient neutron monitor for H*(10) evaluation. The dose correction coefficients vary from one room to another depending on the neutron spectra. The obtained values range from 1.6 to 4 meaning that all dosimeters are over evaluating the exposure..

Keywords
