Description
The measured total efficiency for several source positions has been determined for a large, plastic scintillation detector (NE 102A, 91.5 x 76.0 x 24.5 cm3) used for whole-body counting gamma spectrometry. The results have been compared with Monte Carlo-calculated total efficiencies; the code used was MCNPX 2.60. For 137Cs, there was a good agreement between the measured and calculated total efficiencies. MXNPX was also used to calculate the electron light yield for 137Cs; for the detector material NE 102A, Birks' constant kB was found to be 9.6 mg cm-2 MeV-1. The effect of light losses on spectrum resolution has been investigated for 65Zn. (authors)
