| Abstract: Diagnostic medical exposures make a large contribution to the public exposure to ionizing radiation. Continuing developments in imaging techn ology are changing the pattern of practice in both diagnostic radiology and diagnostic nuclear medicine and we need to assure a reasonable patient protection level. According to our last national study on population exposures from natural and artificial sources of ionizing radiation, 16% of overall annual collective effective dose represent the contribution of diagnostic medical exposure. Of this value, 92 per cent is due to diagnostic X-ray examinations and only 8 per cent arise from diagnostic nuclear medicine procedures. This small contribution to collective dose is mainly the result of their lower frequency compared to that of the X-ray examinations, doses delivered to patients being, on average, ten times higher (1). |
