Assessment of the Radiation and Health Physics Situation in the Area of Ship Repair Enterprises in Kamchatka Krai

The objectives of the study are to examine radiation and health physics situation in area ship repair enterprises servicing ships with nuclear power installation; assess its possible impact on environment population. Materials research methods. territory was conducted by walking gamma survey using portable spectrometric complexes MKS-01A "Multirad-gamma" MKS-AT6101C. Gamma-spectrometric radiochemical methods analysis were used determine specific activity man-made natural radionuclides environmental samples. Results their analysis. Practical medical hygienic measures carried out 2019. It found that ambient equivalent dose rate areas is at level regional values does not exceed 0.12 μSv/h. Radionuclide soil surveyed 4.5 Bq/kg — for 90Sr 12 137Cs, which established norms unrestricted use solid materials. content sea water samples taken closed administrative territorial unit Krasheninnikov Bay average: 137Cs 7 mBq/L, 2.1 mBq/L. When comparing results obtained official data radionuclide Avacha (90Sr up 2.08 mBq/L annual average 1.14 mBq/L), we may state they same as ones. bottom sediment varies within following limits: from 0.14 3 Bq/kg, 0.11 1.5 similar general Thus, characteristics vary little remain practically studies 2014-2015. objects typical region.
