摘要
A geometrically compact detection system with a low cosmic-radiation background rate, 0.55 cts./min in the energy range 3.8-4.8 MeV, and good detection efficiency (14%) for the 4.4 MeV reaction γ-rays, is described. It consists of a 3 in. × 3 in. BGO detector, a plastic-detector anticoincidence shield and a Pb shield. The detection sensitivity of this system is ≲ 20 at.ppm. The performance of BGO detectors in comparision to NaI detectors for measuring 4.4 MeV γ-rays is discussed. © 1990.
