The quantitative assessment of radionuclides transfer to non-human biota using their activity concentration ratios is required for models of predictive doses of ionizing radiation. Based on long-term data regarding activity concentration of radionuclides in the top soil layer of the entire territory of Lithuania, and with the help of ERICA Assessment Tool – a software application that calculates dose rates to selected biota, we estimated the radiological impact on the terrestrial non-human biota with special emphasis on the protected areas located in the vicinity of Ignalina Nuclear Power Plant (INPP). Estimated total dose rates of artificial radionuclides – after-Chernobyl ¹³⁷Cs and ⁹⁰Sr as well as discharged by INPP – and natural radionuclides, such as ²³⁸U and ²³²Th, were found to be less than ERICA screening value of 10 µGy h⁻¹.

使用电离辐射的预测剂量模型需要使用放射性核素的活性浓度比对放射性核素转移到非人类生物区系进行定量评估。根据有关立陶宛整个领土上层土壤中放射性核素活度浓度的长期数据，并借助ERICA评估工具–一种计算选定生物群剂量率的软件应用程序，我们估算了对放射性核素的放射学影响。陆地非人类生物区系，特别侧重于伊格纳利纳核电站（INPP）附近的保护区。切尔诺贝利¹³⁷ Cs和⁹⁰ Sr之后以及INPP排放的人造放射性核素和天然放射性核素（例如^238）的估计总剂量率发现U和²³² Th小于ERICA筛选值10 µGy h ^-1。
