The RAP report presents dose conversion coefficients for each of the RAP geometries which have been estimated using the methodology developed for the ERICA Tool. A large component of the ICRP report comprises a review of radiation effects data for nonhuman species. This is used to suggest a 'derived consideration reference level' (DCRL) for each RAP. The DCRLs are described as a band of dose rate within which there is likely to be some chance of deleterious effects of ionising radiation occurring to individuals of that type of Reference Animal or Plant, derived from a knowledge of defined expected biological effects for that type of organism that, when considered together with other relevant information, can be used as a point of reference to optimise the level of effort expended on environmental protection, dependent upon the overall management objectives and the exposure situation.

A draft report by an ICRP Committee 5 task group presenting transfer parameters for RAPs has been RAPs was released for public consultation . The consultation closes on 1st October 2010in July 2010, the consultation has now closed although comments submitted can be viewed on the ICRP web pages.
