Pv. Ramana et G. Srinivas, RESOLUTION IN LARGE RECTANGULAR NAI(TL) DETECTORS - A STUDY, IEEE transactions on nuclear science, 40(5), 1993, pp. 1325-1328
Experiments were carried out for studying the resolution of 4 in (10 c
m) X 4 in (10 cm) X 16 in (40 cm), NaI(Tl) detectors used in high sens
itivity airborne gamma ray spectrometric surveys. Change of resolution
with source-detector geometry emphasized the inadequacy of the existi
ng specifications for resolution, in explaining the detector response.
A new additional specification for resolution measurement namely ''ov
erall resolution'' is proposed. Measurement and applications of overal
l resolution of the detector are discussed.
