The Radiation Physics Division, part of the Physical Measurement Laboratory at NIST, develops, maintains and disseminates the measurement standards for ionizing radiations and radioactivity in the United States. We also pursue research in the fundamental physical interactions of ionizing and non-ionizing (terahertz) radiation with matter, including in and affecting biological systems. Our theoretical and experimental efforts support radiation and nuclear applications in health care and worker protection, enhance environmental protection, and support national security and defense.
