“…A BaF 2 detector [5] for the positron lifetime spectroscopy and a proportional counter [6] for the energy distribution has previously been used for g ray discrimination through coincidence measurements. However, here, the NaI detector was utilized, and the separation of both type rays was done by using an energy and time coincidence method, thus improving the fast-slow coincidence technique.…”

A b þ -g discrimination set-up was developed and applied to the 22 Na radioisotope. The radioisotope emits positrons (b þ ) and these positrons create g rays by annihilating with electrons. These annihilation g rays were used here, and the discrimination between these positrons and g rays was investigated by the coincidence measurement between time signals and the energy signals. The detection system presented here uses a 3 inch (diameter) by 3 inch (length) NaI(Tl) inorganic scintillation detector for g detection and 3 inch (diameter) by 3 inch (length) plastic scintillation detector for b þ detection.

“…Generally, detectors designed to measure beta-particle energy distributions possess an inherent sensitivity to gamma-ray interactions that result in distortions of the measured distributions [1]. The design of a beta spectrometer depends largely on the measuring task [2][3][4]; if a beta spectrum is to be measured in a mixed beta/gamma field, a separation of the beta energy from that of the gamma rays has to be carried out [5].…”
