Phantom Laboratory
PNNL staff conduct research and development on tissue-substitute materials for the fabrication of instrument calibration phantoms. We also fabricate calibration phantoms to client specifications for in vivo bioassay needs. Solid-tissue substitutes that are available for equipment calibrations include lung phantoms for the Realistic Torso phantom, lung phantoms for the JAERI Torso phantom, whole-body BOMAB phantoms, and organ phantoms including liver, skeletal, thyroid, and lymph nodes. Unique tissue-substitutes with attenuation coefficients modeled after ICRU Publications 44 and 48 values can be labeled with radionuclides in uniform bio-distributions. The laboratory provides the calibration lung phantoms for the USDOE Laboratory Accreditation Program for Radiobioassay, and has provided many government and private customers with custom calibration phantom applications.
U.S. Department of Energy Phantom Library
PNNL operates the USDOE Phantom Library for the Office of Worker Health and Safety, EH-52. The library loans high-quality calibration phantoms used in in-vivo bioassay calibration needs. Phantoms are loaned without cost to DOE Laboratories and other government agencies, and for a minor cost-recovery fee to other clients. The inventory includes the largest collection of original LLNL torso lung phantoms, liver, lymph node, and thyroid phantoms; and whole body phantoms including the BOMAB and Fission Product phantoms. The DOE Phantom Library catalog can be viewed at http://www.pnl.gov/phantom/. A unique human skeletal phantom containing a distribution of Am-241 is also available through a partnership with the United States Transuranium and Uranium Registries.
