Abstract
Several topics related to the radiation protection in medical use of ionizing radiation are discussed. The occurrence of the acute effect of ionizing radiation among the patientes who are exposed in endvascular surgery may show the negligence of medical physicists working in the field of radiation protection.
Publication of the "Basic Safety Standards" of Internatiol Atomic Energy Agency will accelerate the movement of changing the regulatory system as to fit with 1990 recommendation of ICRP, which may cause several exhausting problems for medical physicists. Necessity of the discussion on the quantity used in diagnostic exposure is also pointed out.
