Radiation Physics Staff

Within this site we have provided biographies for a small subset of individuals who worked in the Radiation Physics Building (aka, Building 245) since its construction. Many of these individuals were involved in designing Building 245 during the early 60s. Others are in the NIST Portrait Gallery. All are widely cited as experts in radiation theory and measurements, and all have received major awards, including Department of Commerce Gold and Silver awards.
