The DOE in-vivo phantom library program
The use of improved in vivo bioassay calibration phantoms in recent years has led to significant advances in the detection capabilities of in vivo counting laboratories, and increased ability to cross-calibrate various systems and laboratories for standardization purposes in DOE programs. The cost of these phantoms are significant, though, and this inhibits successful intercomparisons for improving calibrations. A recent CIRRPC Workshop on Internal Dosimetry in April 1992 recommended establishing intercomparison programs for in vivo measurements and improved phantom designs. Improved phantoms, developed at PNL with NIST-traceable source reference material loadings, proven solid tissue substitutes, and extensive documentation on construction, activity, and physical and chemical composition are available through a newly operational library. These phantoms use original LLNL molds and existing BOMAB phantom shells, but with improved tissue substitutes. All phantom materials have been extensively tested for their chemical, physical, and radiation transmission properties, and are tailored for identical transmission characteristics at the photon energies of concern. PNL has been pursuing approval from NIST for {open_quotes}certification{close_quotes} of these phantoms. The DOE Phantom Library loans organ, whole-body, and through cooperation with USTR, an Am-241 skeletal phantom to DOE contractor laboratories without cost. Only the price of shipping the phantom is requested. This paper will discuss the operation of the library, the current and planned holdings, the quality of phantom construction, and planning for NIST cooperation in certifying these phantoms.
