Radiological and Environmental Sciences Laboratory

The Radiological and Environmental Sciences Laboratory (RESL) is a federally owned and operated laboratory by the United States Department of Energy (DOE) located in the Central Facilities Area of the Idaho National Laboratory near Idaho Falls, Idaho. The laboratory's focus is primarily in analytical chemistry, radiation protection, and as a reference laboratory for numerous Performance Evaluation Programs. RESL provides technical support and quality assurance metrology, which is directly traceable to the National Institute of Standards and Technology (NIST).

RESL staff consists of professional chemists, physicists (including health physicists), engineers, computer programmers, and related technicians. The staff has academic training to the doctorate level. Individual staff members participate in professional society activities, in working groups and committees, such as American Society for Testing and Materials (ASTM), International Organization for Standardization (ISO) and American National Standards Institute (ANSI) committees, the Health Physics Society, and on editorial and accreditation boards.
