This chapter describes the origin and status of a family of four new consensus standards on radiation detection instruments for Department of Homeland Security (DHS) applications. The standards were developed under the auspices of American National Standards Institute (ANSI) committees N42 (Nuclear Instrumentation) and N42-RPI (Radiation Protection Instrumentation) and cover the following: Alarming personal radiation detectors for photons and neutrons (ANSI N42.32); Portable photon radiation exposure rate detection instruments (ANSI N 42.33); P0rtable radionuclide detectors with neutron detection capability (ANSI N 42.34); and Portal radiation monitors for personnel, packages, and vehicles (ANSI N 42.35). The application of these types of instruments to homeland security had not previously been considered by ANSI. In addition, there was a need to encourage the instrument manufacturing community to develop new technologies and better-perfom1ing instruments. The origin, leadership, contributors, time lines, and highlights of the standards are presented below, along with information about the extensive testing and evaluation (T&E) protocols that were developed for use by DHS to rate candidate instrumentation. Critical issues for matching appropriate instruments to expected applications and the need for effective user training are also discussed. Together, the standards, T&E protocols, and associated guidance and training documents should ensure that appropriate radiation detection instruments are placed in the hands of capable users.
