Highly sensitive spectrometric γ-detection assemblies are developed using a comprehensive approach (optimization of crystal growth conditions as well as of treatment and packing of scintillators, creation of low-noise charge-sensitive preamplifiers and shapers). The detection assemblies with CsI(Tl)≤100 cm3have a sensitivity of about 20 pulse/s(mcR/h), their energy resolution with respect to137Cs γ-line being ≤8.5%. The assemblies with lesser scintillator volumes (1-5 cm3) provide a resolution lower than 6% with respect to137Cs and ≤40% with respect to241Am. © 2004 Elsevier B.V. All rights reserved.
