Risiko der Strahlenbelastung in Diagnostik und Therapie.

The use of radiation in medicine gives rise to average exposure which approximates the natural background dose. It is thus the largest manmade source of radiation exposure. The somatic and genetic risks can be quite reliably estimated from animal experiments and from observations on groups of people who have been exposed to radiation. The benefits of correctly applied radiation in medicine far outweigh the risks. Nevertheless, a reduction of the radiation dose by quality control and carefully considered application should be strived for
