In my presentation I will briefly touch upon such subjects including "about ICRP and UNSCEAR", "Sources of radiation exposure", "health effects attributable to radiation exposure" and "framework of radiation protection" based on my experiences as a member of main commission of ICRP and chairman of UNSCEAR.
With the increasing recognition of hazardous effects of radiation ICRP was established in 1928 as a committee of the ICR. Its field of work has widened from protection in medical radiology to all aspects of protection against ionizing radiation. The latest general recommendation was issued in 1990 as publication 60. The commission is now preparing the new recommendation to be completed probably in 2007. In the latest ICRP general meeting held Sept. 9-16, 2005, a new committee 5 was started in order to discuss and report on radiation protection of environment or non-human biota.
UNSCEAR was founded in 1955, having been urged by increasing concerns worldwide about the effects of fallout from atmospheric nuclear testing. UNSCEAR is the UN body with a mandate to provide estimates on the levels and effects of radiation exposures. It collects information, reviews and validates scientific soundness of the information.
On these scientific basis ICRP provides guidance on the fundamental principles on which appropriate radiological protection can be based. UNSCEAR's estimates, together with the ICRP recommendations, are used by the IAEA in discharging its statutory responsibilities of establishing BSS and providing for their application.
