Implication of new International Commission on Radiological Protection dose limit for eye lens: A brief review of TECDOC-1731

摘要

ICRP now recommends an equivalent dose limit for the lens of the eye of 20 mSv in a year, averaged over defined periods of 5 years, with no single year exceeding 50 mSv. In December 2013, IAEA brought out a TECDOC-1731, entitled "Implications for occupational radiation protection of the new dose limit for the lens of the eye," providing interim guidance for application of the limit in operational settings of planned exposure situations. This brief review article is an attempt to bring out salient features of document for the benefit of the readers and operational radiation protection personnel.
