[en] The Committee on Interagency Radiation Research and Policy Coordination (CIRRPC) was established on April 9, 1984 by the Office of Science and Technology Policy (OSTP) under the authority of the Federal Coordinating Council for Science, Engineering and Technology (FCCSET). It is chaired by OSTP. CIRRPC membership consists of those agencies having specific responsibilities or interest in radiation research and/or policy. CIRRPC has two elements: The Committee itself, consisting of subcabinet and senior policy level representatives, and a Science Panel, consisting of senior radiation scientists from the respective member agencies. The structure and membership of CIRRPC is shown in Figure 2. It was decided at the inception of CIRRPC to identify the radiation issues of concern to the Federal agencies, Congress, and professional societies faced with radiation policy or scientific issues. It was felt that a current list of national radiation issues should be assembled so that CIRRPC could concentrate on these issues and the dividends from CIRRPC's resources could be maximized at the earliest possible time. These issues are listed
