Challenges of the New ICRP Eye Lens Dose Limit

Abstract

Radiation protection in the use of ionizing radiation in medicine is becoming more and more important because of its increasing use for imaging and therapy and because of complex procedures and technology. The US study showed that the population dose due to medical uses of ionizing radiation increased to about 49% of the total population radiation dose in year 2006 [1]. The increase is due to the wide use of medical man-made sources of radiation in computed tomography (CT) imaging, interventional radiology and nuclear medicine. Justification of medical exposures and optimization of patient and staff protection are the thrust of the International Atomic Energy Agency (IAEA) and other international communities and regulatory bodies.
