Safety and Security
Providing the National primary standards for radiation and radioactivity measurements and standards places the Division in a unique position to be leaders, and to work with other agencies, in the development of consensus performance standards and testing protocols for radiation and neutron detectors, x-ray and high energy gamma-ray interrogation methods, and x-ray imaging systems, as well as guiding developments in data formats for instrumentation output and training standards for instrumentation used by emergency and first responders. Providing key measurement tractability for secondary calibration laboratories allows dissemination of NIST standards to a vast community of users of ionizing radiation.
