ERICA2.0软件和R&D128程序中^(41)Ar和^(85)Kr核素对陆生生物辐射剂量率估算对比的初步研究

Preliminary Study on the Comparison Between the Estimation of Radiation Dose Rate of ^(41)Ar and ^(85)Kr Nuclides to Terrestrial Organisms in Erica2.0 Software and R&D128 Program

在我国的生物辐射影响评价中,现阶段计算惰性气体对生物的辐射剂量影响大多采用R&D128程序,ERICA软件计算其他核素对生物的剂量率。本文从参考生物、惰性气体核素、计算公式、主要参数等方面对2021年升版的ERICA2.0软件和R&D128程序进行了对比。以我国某核电厂两台机组为例,分别使用这两个方法计算了^(41)Ar和^(85)Kr核素对生物的辐射剂量率。计算结果表明,对于惰性气体核素的辐射影响计算,^(41)Ar和^(85)Kr的计算使用R&D128程序是相对保守和可行的;对于其他的惰性气体的计算,可采用ERICA2.0软件。因此在生物辐射影响评价中,可将R&D128程序和ERICA2.0软件结合使用,进行惰性气体对生物造成的辐射剂量的计算和分析。

In China’s biological radiation impact assessment,the R&D128 program is mostly used to calculate the radiation dose impact of noble gases on organisms at this stage,and the Erica software is used to calculate the dose rate of other nuclides on organisms.This paper compares the Erica2.0 software upgraded in 2021 with the R&D128 program from the aspects of reference biology,noble gases nuclide,calculation formula and main parameters.Taking the two units of a nuclear power plant as examples,the biological radiation dose rates of ^(41)Ar and ^(85)Kr nuclides were calculated by using these two methods respectively.The calculation results show that it is relatively conservative and feasible to use the R&D128 program to calculate the radiation effects of noble gas nuclides in ^(41)Ar and ^(85)Kr.For the calculation of other noble gases,the Erica2.0 software can be used.Therefore,in the biological radiation impact assessment,the R&D128 program and the Erica2.0 software can be combined to calculate and analyze the radiation dose caused by noble gases to organisms.
