II. Background

This document is Federal Guidance Report No. 14 (FGR 14), “Radiation Protection Guidance for Diagnostic and Interventional X-ray Procedures.” It replaces Federal Guidance Report No. 9, “Radiation Protection Guidance for Diagnostic X-rays,” which was released in October 1976. Federal Guidance reports were initiated under the Federal Radiation Council (FRC), which was formed in 1959, through Executive Order 10831. A decade later its functions were transferred to the Administrator of the newly formed Environmental Protection Agency (EPA) as part of Reorganization Plan No. 3 of 1970. Under these authorities it is the responsibility of the Administrator to “advise the President with respect to radiation matters, directly or indirectly affecting health, including guidance for all Federal agencies in the formulation of radiation standards and in the establishment and execution of programs of cooperation with States.” (42 U.S.C. 2021(h)) While EPA believes that this guidance will be useful to the broader medical community, the recommendations in FGR 14 are specifically directed to the use of diagnostic and interventional x-rays in federal facilities. A draft version of FGR 14 is now available for review and comment. It can be found on the agency's Radiation Protection Web site at:​radiation.
