title: Opportunities for scientists to influence policy: when does radiation metrology matter in development of national policy?
abstract: Accurate measurements of radiation and radioactivity rarely rise to the level of national policy. The things that matter most to ordinary citizens do not normally include questions of science and technology. Citizens are more often concerned with issues close to home relating to commerce, health, safety, security and the environment. When questions of confidence in measurements arise, they are first directed to the ministry that has responsibilities in that area. When the required uncertainty in field measurements challenges the capability of the regulatory authorities, the National Metrology Institute may be asked to develop transfer standards to enhance the capabilities of the ministry with the mission lead. In this paper, we will consider eight instances over the past nine decades in which questions in radiation and radionuclide metrology in the US did rise to the level that they influenced decisions on national policy. These eight examples share some common threads. Radioactivity and ionizing radiation are useful tools in many disciplines, but can often represent potential or perceived threats to health and public safety. When unforeseen applications of radiation arise, or when environmental radioactivity from natural and man-made sources presents a possible health hazard, the radiation metrologists may be called upon to provide the technical underpinning for policy development.
