We present new results on the radiopurity of a 3.4-kg NaI(Tl) crystal scintillator operated in SABRE proof-of-principle detector setup. The amount potassium contamination, determined by direct counting radioactive K40, is found to be 2.2±1.5 ppb, lowest ever achieved for crystals. With active veto, average background rate 1–6 keV energy region interest (ROI) 1.20±0.05 counts/day/kg/keV, which b...

Particle detectors based on liquid argon are now recognised as an attractive technology for dark matter direct detection and coherent elastic neutrino-nucleus scattering measurement. A program using a dual-phase detector with fiducial mass of 200 kg to detect at Taishan Nuclear Power Plant has been proposed. SiPMs will be used the photon sensor because their high radio-purity efficiency. S13370...

Radioactivity was measured for 170 cow's milk samples in Salah-Din governorate. Samples were by a gamma spectrometry system, using high purity germanium (HPGe) detector. The detector shielded 10 cm all sides with cadmium copper the inner sides. selected characteristic peaks detection of different ware 1460kev K-40. energy calibration performed set standard ray sources Eu-152. results show prese...

Bismuth germanate (BGO) is a well known high density scintillating material widely used in many applications such as energy physics and medical imaging. silicate (BSO) features properties similar to BGO terms of stopping power Cherenkov photon yield with lower scintillation light output but faster decay time, thus being more attractive for high-rate environments. Mixed crystals Bi 4 (Ge x Si 1 ...
