Welcome to ICRPædia, the home for information on The System of Radiological Protection developed by The International Commission on Radiological Protection (ICRP). ICRPædia is the work of ICRP members.

The System of Radiological Protection is the basis of all standards, regulations, and practice of radiological protection world-wide, for the protection of patients, workers, the public, and the environment from ionising radiation.

The definitive reference for the recommendations and guidance of ICRP is the dedicated journal Annals of the ICRP.

ICRPædia is still in it's infancy, and growing. Come back regularly to see what's new.
