Radiation-associated lens opacities

Dr René Pfleger et al.

Radiation-associated lens opacities, also known as radiation-induced cataracts, address changes in the lens of the eye by radiation.

The lens of the eye is one of the most radiosensitive tissues in the body. Exposure to ionizing radiation can cause cataract formation which can develop over years to decades. It is most often encountered as posterior subcapsular cataract (PSC). Early stages may not cause visual impairment.  The severity of opacities has been shown to increase progressively with dose, ultimately causing vision impairment. The latency of changes has been shown to be inversely related to dose (accumulative effects).

There seems to be no threshold why recommendations for occupational exposure dose limits have recently been reduced by International Commission on Radiological Protection (ICRP) by > 8-fold.
