W10  Dose to the Lens of the Eye: The Latest Scientific Recommendations

The NRC is sponsoring this session to listen to perspectives on the recent recommendation by the National Council on Radiation Protection and Measurements (NCRP) to reduce the dose limit to the lens of the eye to 5 rads (50 milligray) per year—equivalent to 5 rem (50 millisieverts per year for low linear energy transfer radiation. The NRC established its current dose limit of 15 rem (150 millisieverts) per year in 1991 based on the International Commission on Radiological Protection’s (ICRP’s) recommendations at the time (i.e., ICRP Publication 60). The NCRP proposed reduction is based on recent epidemiological evidence suggesting that vision impairing cataracts can occur at doses lower than previously considered when the current NRC dose limit was established.
