ICRPædia Guide to Dose Coefficients

ICRP develops dose coefficients to simplify the calculation of absorbed dose, equivalent dose, and effective dose from external radiation or intakes of radionuclides.

Current dose coefficients are based on the system of radiological protection described in ICRP Publication 60. For convenience, two compendia have been published to cover doses to workers and the public, and doses to patients from radiopharmaceuticals, based on several previous publications now superseded by these two:

Publication 119 Compendium of Dose Coefficients based on ICRP Publication 60

Publication 128 Radiation Dose to Patients from Radiopharmaceuticals: A Compendium of Current Information Related to Frequently Used Substances

In addition, Publication 123 Assessment of Radiation Exposure of Astronauts in Space includes conversion coefficients developed for the particular radiation fields in space which are very different from those usually encountered on Earth.

New dose coefficients based on the current system of radiological protection, described in ICRP Publication 103, are now being published. These coefficients will supersede those based on ICRP Publication 60.
