Lens of the Eye - Implications and Implementation
In December 2013, the IAEA published a TECDOC entitled Implications for Occupational Radiation Protection of the New Dose Limit for the
Lens of the Eye. This TECDOC was based on the discussions held during the Technical Meeting in October, 2012.
The IAEA Safety Requirements publication: GSR Part 3 (Interim edition): Radiation Protection and Safety of Radiation Sources: International Basic Safety Standards, was approved by the IAEA Board of Governors in September 2011 and issued as an interim edition in November 2011. The equivalent dose limit for the lens of the eye for occupational exposure in planned exposure situations was reduced from 150 mSv per year to 20 mSv per year, averaged over defined periods of five years, with no single year exceeding 50 mSv.
The purpose of the TECDOC is to provide guidance on implementing the new occupational dose limit and to identify issues for which further information is required. In the longer term, the guidance will form the
basis for the guidance in relation to the new dose limit for the lens of the eye in the Safety Guides DS453: Occupational Radiation Protection and DS399: Radiation Safety in the Medical Uses of Ionizing Radiation.
