Lung Phantoms
The DOE Phantom Library maintains the following inventory of calibration lung phantoms for use with the Torso phantom. Lung sets are from several different sources - LLNL original sets, RESL DOELAP sets, and Humanoid Systems or RSD sets. Table Lung-nCi indicates the radionuclide data for the inventory of lung sets available in the library. The activities listed are the total activity of both the left and right lungs. All lung activities are relatively equally distributed among the right and left tissues. Detailed information will be provided with the phantom regarding the specific left and right lung activities. The table contains subheadings, organized by measurement category as defined in DOE Technical Standard DOE-STD-1112-98, Laboratory Accreditation Program for Radiobioassay. Unless otherwise indicated, the calibration lungs listed here have proven traceable pedigrees (directly or by cross-reference) to national reference standards organizations, such as NIST (NBS), and have been favorably intercompared with other LLNL Lung sets.
Available lung phantoms contain the following radioactive materials:
- Plutonium (nCi): Useful for transuranium elements via L x-ray calibration.
- Americium-241 (nCi)
- Natural Uranium (nCi): Useful for thorium-234 calibration.
- Uranium-235 (nCi)
- Other (nCi): Useful for fission product and other measurements, some of which are not defined by DOE Technical Standard DOE-STD-1112-98, Laboratory Accreditation Program for Radiobioassay.
