Abstract (english)

The paper analyses results of spatio-temporal radiological risk assessment
scenarios based on existing in-situ long-term monitoring data from a natural
gas processing plant to analyse the effect of different input data on the
assessment outcome. The ERICA Assessment Tool was used to estimate the dose
rates to biota and potential impacts due to the exposure to ionising
radiation. The input data for radiological risk assessment scenarios
included annual data on activity concentration of radionuclides in soil
from measurements performed from 1994 to 2016 and laboratory
gamma-spectrometric data related to the period from 2014 to 2019. Predicted
total dose rate to biota was generally below the ERICA Tool's screening dose
rate of 10 μGyh-1 or slightly above, with the highest total dose rate
estimated for lichen and bryophytes. Total dose rates to lichen and
bryophytes in the studied period show certain temporal variation, but a
specific trend was not detected. Estimated total dose rates to biota from
different assessment scenarios were below internationally proposed reference
levels for which no detrimental effects are expected. The overall potential
radiological risk to terrestrial biota from the operation of the natural gas
processing plant was found to be negligible.
