The recommendations of the BWG contributed to the establishing of three working groups considering environmental protections issues within the ERMAS II programme:

Biota modelling group
OBJECTIVES: The aim of the work is to improve Member States' capabilities for protection of the environment by comparing and validating models being used, or developed, for biota dose assessment (that may be used) as part of regulatory process of licensing and compliance monitoring of authorised releases of radionuclides.

Wildlife Transfer Coefficient Handbook
OBJECTIVES: The focus of the Working Group is to contribute to the development and implementation of an online Wildlife Transfer Parameter Database which will be applied in the production of a Technical Reports Series (TRS) Handbook on Wildlife Transfer Coefficients. In parallel a core group was established by the IAEA in cooperation with International Union of Radioecology (IUR) to develop an online concentration ratio database, initially populated with the ERICA data, to provide data tables for the Handbook. A further objective of the Working Group is to provide a peer review of the text of the above mentioned Handbook.

Biota Dose Effects Modelling
OBJECTIVES: The Working Group works with a number of subgroups to derive relationships between exposures to ionizing radiation and effects on flora and fauna. Within this context, existing dose-effects databases will be updated, dose-response relationships will be analysed, models for the impact of exposures to populations will be attempted, the exposure to multiple stressors will be investigated and statistical methods for analysing dose-effects relationships will be further developed.
