Radiochemical Processing Laboratory

Our Radiochemical Processing Laboratory just north of the city of Richland, in southeastern Washington State is a 144,092 ft2 building with 38,000 ft2 of laboratory space and more than
8,500 ft2 of hot cell space in a security-protected area. The laboratory was designed and is operated as a DOE Hazard Category 2 facility for work with microgram to kilogram quantities of fissionable and nonfissionable radioactive materials ranging from picocurie to megacurie levels of activity. The facility contains extensive wet laboratories, shielded glove boxes, wet radiochemistry fume hoods, and associated equipment for conducting radiochemical separations, radioanalytical measurements, radioactive materials characterization, and radioactive and hazardous waste management.

318 Building

PNNL's 318 Building is a Radiological Exposure and Metrology Calibration and Standards Laboratory. Laboratory staff provide expertise and experience in health physics, artifact irradiations, radiation measurements, instrument testing, dosimetry, and calibrations. Operated by the Energy and Environment Directorate, it offers technical expertise for design, development, testing, and calibration of radiation-measuring devices as well as specimen irradiations for research purposes. Traceability to the National Institutes of Standards and Technology (NIST) is maintained through participation in the National Voluntary Accreditation Program (NVLAP) as an accredited Calibration Laboratory for Ionizing Radiation (NVLAP Lab Code 105020). The 318 Building houses several ionizing radiation laboratories for irradiating artifacts with beta, photon, and neutron radiations of various energies. These laboratories include: Source Well Room, High Exposure Facility, Beta Room, X-Ray Laboratory, and the Low Scatter Neutron Facility that includes high activity Cf-252 sources and a neutron generator.
