Only since quite recently has man been subjected to irradiation which, as the result of medical and industrial development has been added to the radiation from natural sources. According to the investigations quoted artificinl radiation accounts for 20 to 25% of the total radiation level. Atomic test explosions have so far only made an insignificant contribution, The same can still be said of the industrial application of nuclear energy which is still in its infancy. It has been estimated that people living in Europe will over a period of 30 years be subjected to a total dose of radiation from 2,500 to 4,000 mr. Of this total dose received in 30 years about 75O to 850 mr will be contributed by medical and industrial appuntenances, the overwhelming share of 600 to 700 mr being the result of medical x-ray diagnosis. The atmospheric radioactivity has been estimated (incl. rainfall etc.) at 20 to 30 mr over a period of 30 years and will therefore not represent any hazards as far as external, direct radiation is concerned. The possible absorption by and accumulation of radiating substances in the body must, however, be carefully studied and special consideration must be given to fission products with a long half-life. Regarding the accumulation of certain substances in plants and animals it is still not possible to make a generally valid statement though a great number of facts have been collected. The present internationally agreed permissible dose rates are used as a criterion specially for the maximum permissible concentrations of radioisotopes, isotope mixtures, shontterm absorption, catastrophies, and also include soil contamination.
