“…In part, this is a consequence of the different organisms considered in the three models. It is also in agreement with other comparisons of models/approaches used to estimate exposure of biota which have demonstrated that the dosimetry components generally estimate comparable results [1][2][3]. The greater variability observed in estimated RQ values between models when assuming 1 Bq kg −1 in freshwater sediments may be the consequence of RESRAD-BIOTA using terrestrial soil-soil water k d values rather than freshwater sediment-water k d values [10].…”

Abstract. In common with the assessment of chemical stressors many of the methods used for the assessment of risk of non-human biota exposed to radiation use tiered approaches. The initial tier within these approaches is designed to be simple and conservative with the aim to identify sites of negligible concern which can be excluded from more detailed assessment with a high degree of confidence. In this paper we compare the outputs of the screening tiers of three tools which are freely available as software packages. Outputs were compared for terrestrial and freshwater ecosystems assuming 1 Bq per unit media. Considerable variability between the risk quotients (RQ) estimated by the three approaches used was seen for some radionuclide-organism-ecosystem combinations. Reasons for this are explored with differences in transfer parameters used by the models being a common contributor. The large variation within RQ values estimated by the approaches requires further investigation as it does not promote the level of confidence required by the user. The practicalities of applying a single generic screening dose rate in assessments are also explored.

“…Variation was greater for the estimation of external dose rates, most notably for -and -emitters (e.g. from 3 H, plutonium and some naturally occurring radionuclides). However, it is generally accepted that external exposure of biota by such emitters is of little radiological significance due to the low range of -and -emitters in matter.…”

Findings and recommendations from an international comparison of models and approaches for the estimation of radiological exposure to non-human biota

Abstract. There is general international acceptance of the need to demonstrate that the environment is protected from ionising radiation. In some countries requirements and guidelines for the protection of non-human biota are already in place. As a consequence a number of models and approaches have been proposed for the estimation of the exposure of non-human biota to ionising radiation. The IAEA EMRAS programme's Biota Working Group has conducted the most comprehensive intercomparison of the predictions of these approaches to date. In this paper, we present an overview of the activities of the Biota Working Group concentrating on its conclusions and recommendations.
