“…Shen et al (1987) used plastic scintillators to measure spectra, from which they subsequently calculated doses using electron transport theory as applied to TLDs. Swinth et al (1989) constructed a combination proportional counter-plastic scintillation counter for measuring beta spectra and dose. They used coincidence gating to exclude gamma events.…”

“…To accurately correct beta dosimeter or survey instrument readings, one must know or measure the beta particle spectra in the field and make corrections for the gamma ray contribution. [2] A b þ -g separation method is presented here, in this respect, to distinguish them.…”

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.
