摘要
The work presents the evaluation of new neutron electronic personal dosimeter (EPD) at the Cernavoda NPP. As the new EPDs should fulfill the specific conditions inside a CANDU nuclear power plant, they were also checked for gamma dose rejection in several neutron fields inside the power plant with focus on a specific location - Heat Transport Auxiliary Room, with a high level of epithermal neutrons. An Eberline ASP-2/NRD dosimeter was used as neutron field reference while gamma dose rejections were evaluated by a Shepherd 78 calibrator. In these conditions, all evaluated EPDs passed with a good degree of confidence to the reference value and proven that they are suitable for personnel deep dose evaluation with a relative neutron spectra correction coefficient.
