Provides a review of early and late effects of radiation in normal tissues and organs with respect to radiation protection.

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.

Lessons from accidental exposures are an invaluable resource for revealing vulnerable aspects of the practice of radiotherapy, and for providing guidance for the prevention of future occurrences. This report provides lessons from retrospective information in Sections 2 and 4.

Describes the terms and methods used to assess the radiation exposure of astronauts, and provides data for the assessment of organ doses.
