The purpose of the present work is to analyze the long-term yearly average volumetric activity in the surface air and the yearly absorbed dose of β- and γ-radiation in the spread zone of continuous emissions from NPP. The particulars of the spreading of the emission radionuclides and the associated yearly absorbed radiation dose are determined. It is shown that the atmospheric volumetric activity of radionuclides due to continuous emissions is 10⁵ times lower than the NRB-99/2009 standards and the yearly absorbed dose is 1000 times lower than the level of the natural radiation background.

连续放射性排放的地表空气中放射性核素的长期年平均体积活度和年吸收剂量的分析（列宁格勒NPP-2）

本工作的目的是分析地表空气的长期年平均体积活度以及NPP连续排放扩散区中β-和γ辐射的年吸收剂量。确定了发射放射性核素的扩散特性和相关的年吸收辐射剂量。结果表明，由于连续排放而引起的放射性核素在大气中的体积活度比NRB-99 / 2009标准低10 ⁵倍，年吸收剂量比自然辐射本底水平低1000倍。
