The article presents a study of neutron fields at the Rostov Nuclear Power Plant (NPP), including an analysis of the energy distribution of neutron radiation at workplaces. The research is based on current scientific data, recommendations from international organizations, and the application of modern instruments and methodologies. Measurements were conducted at 16 workplaces within units 3 and 4, as well as in a special auxiliary building of the Rostov NPP. The results of ambient dose equivalent (H*(10)) measurements for neutron radiation, obtained using three different instruments, show significant data variability. It was found that the ratios of readings from the MKS-AT1117M device with BDKN-03 and BDKN-06 detectors range from 0.8 to 4.2, while for the MKS-AT1117M with BDKN-01 and BDKN-06 detectors, the ratios vary between 1.7 and 15.6. The average neutron energy values in the surveyed areas range from 0.002 to 1.9 MeV. Based on the experimental data, reliable values of the ambient dose equivalent H*(10) and personal dose equivalent Hp(10) were determined. To enhance radiation monitoring, a methodology for assessing the ambient dose equivalent rate and the effective dose of neutron exposure for personnel at the Rostov NPP has been developed and approved.
