The IRD/CNEN Whole-Body Counting Facility: Background and Calibration Results

A whole-body counter installation was constructed and calibrated for the determination of small amounts of gamma/X ray photon emitters in the energy range from 10 keV to 3 MeV. Three phoswich detectors, as well as one 20.3 cm diam. x 10.2 cm thick NaI(Tl) and one 7.6 cm collimated NaI(Tl), were inst...

Zusammenfassung:	A whole-body counter installation was constructed and calibrated for the determination of small amounts of gamma/X ray photon emitters in the energy range from 10 keV to 3 MeV. Three phoswich detectors, as well as one 20.3 cm diam. x 10.2 cm thick NaI(Tl) and one 7.6 cm collimated NaI(Tl), were installed inside a steel monitoring room. An additional 'graded Z' lining consisting of Pb, Cd and Cu has been added to the interior of the room. The facility was calibrated using specific, anthropomorphic phantoms for each site of measurement. This paper will discuss the results of background and calibration measurements performed at this facility.
