By the end of the decade, the International Congress of Radiology established the International X-ray and Radiant Protection Committee. The four runner of today's International Commission on Radiological Protection, which recognized the hazards of radiation and the need for control. Within a few years, this committee recommended the limitation of dose received by radiation workers. Its recommendation served as the basis for worldwide radiation protection until the 1950s. One year later, the US Advisory Committee on X-ray and Radiant Protection was formed. This committee is the predecessor of the National Council on Radiation Protection and Measurements, which was reorganized in 1964.
