[Radiation burden from X-ray diagnosis and new technological developments (author's transl)].

Radiation exposure of the population is expressed nowadays in terms of genetically significant dose and its individual components are compared. The calculations necessary for the present considerations have been carried out. As a basis for evaluating radiation protection, the natural sources of radiation and therir variations are used. The dose of 110 mrem/a for the population of the Federal Republic is subject os considerable variations. Artificially produced radiation contributes a total of 60 mrem/a to the exposure. Of this, most is contributed by medical sources with 50 mrem/a, second is exposure due to atom bomb research. Other sources of radiation, such as occupational exposure, its use in research and technology, and use of nuclear technology, contribute little to total exposure, each producing about 1 mrem/a. The data provided is supported by numerical evidence.
