Medical Radiophysics in Sweden 1920-1950

This collocation has been made for several reasons.One is that through the development of nuclear physics during the last decade, medical radiophysics has attained a more immediate interest and may be expected to become a branch of applied physics, which, within the next few years will be of very great importance.A survey of the organization of medical radiophysics in Sweden can therefore be supposed to be of some general interest, as this subject has developed along somewhat different lines in Sweden than in other countries, its various partsresearch and teaching, hospital work, radiation protection and dosage control -to a large extent being combined in one and the same institrute.A further reason is that a review of the development and a consideration of existing organizations may be of use in the reorganization of medical radiophysics which may be needed in other countries as well as it is in Sweden.Finally, during the most recent years, inquiries on a steadily increasing scale have come in from abroad about the supervisory activities of the Institute of Radiophysics.For this latter reason an English translation of the laws and regulations which bear upon these activities seems desirable.
