Provides updated guidance on radiological protection from cosmic radiation in aviation, taking into account the International Commission on Radiological Protection (ICRP) system of radiological protection, the data on exposures in aviation, and experience gained worldwide in the management of exposures in aviation.

A title, in which, the commission includes a section on the protection of the environment, and indicated that it would be further developing its approach to this subject by way of a set of Reference Animals and Plants (RAPs) as the basis for relating exposure to dose, and dose to radiation effects, for different types of animals and plants.

Provides information relating to radiation dose to patients, including biokinetic models, biokinetic data, dose coefficients for organ and tissue absorbed doses. This report includes new information for 82Rb-chloride, iodide (123I, 124I, 125I, and 131I) and 123I labelled 2ss-carbomethoxy 3ss-(4-iodophenyl)-N-(3-fluoropropyl) nortropane (FPCIT).

Gives fluence to dose conversion coefficients for both effective dose and organ absorbed doses for various types of external exposures, consistent with the 2007 Recommendations of the ICRP.
