This database collates data to provide parameter values for use in environmental radiological assessments to estimate the transfer of radioactivity to wildlife. The database has been updated today (12/12/13). Full details of the update will be made available soon. There may be some minor changes with the data over the next few weeks as further evaluation of the changed data takes place. If you have any queries please contact us at the wildlifetransfer@gmail.com address. We will put a note here when the database update is complete. The database was started to aid both: (i) the International Atomic Energy Agency (IAEA) in the production of a handbook on wildlife transfer parameters (IAEA Technical Report Series now in press); and (ii) the derivation of transfer parameter values for the International Commission on Radiological Protections (ICRP) list of Reference Animals and Plants (RAPs) (ICRP Publication 114). The database has been designed and supported by the following organisations: Environment Agency, England and Wales Norwegian Radiation Protection Authority, Norway Centre for Ecology and Hydrology, NERC, UK University of Stirling, UK The STAR Radioecology Network of Excellence
