There are a number of models and approaches to estimate radiation exposure of wild animals. These models and approaches have to be validated in terms of internal and external dose assessment on wildlife to ensure that the uncertainties during those processes are considered. Internal dose rates can be compared to measure radionuclide activity concentrations. However, to validate external dose rates direct dosimetry measurements of wild organisms in field are desirable.

The project will develop practical dose measurement technologies for accurately assessing external radiation exposure of wildlife. The focus will be on terrestrial wild mammals and birds. Passive dosimeters attached on collars will be used to measure external dose rate on canid species, small mammals and birds. The initial step in this research is to critically evaluate the different technologies. Once the most appropriate technologies have been identified for different organism and exposure scenarios they will be calibrated under laboratory conditions (in collaboration with Public Health England). Subsequently they will be applied in field studies at different sites.

This presentation will present an initial critical review of the available technologies and discuss their fitness for purpose.
