Radioactive contamination of CaWO4, ZnWO4, CdWO4, and Gd2SiO5:Ce crystal scintillators
Radioactive contaminations of CaWO4, ZnWO4, CdWO4, and Gd2SiO5:Ce crystal scintillators were measured in the Solotvina Underground Laboratory. The Monte Carlo simulation of contributing radioactive sources, the time-amplitude and pulse-shape analyses of the experimental data were applied. CaWO4 and...

| description | Radioactive contaminations of CaWO4, ZnWO4, CdWO4, and Gd2SiO5:Ce crystal scintillators were measured in the Solotvina Underground Laboratory. The Monte Carlo simulation of contributing radioactive sources, the time-amplitude and pulse-shape analyses of the experimental data were applied. CaWO4 and GSO scintillators are considerably polluted by uranium and thorium, while the total {alpha} activity in ZnWO4 and CdWO4 scintillators does not exceed the level of a few mBq/kg. Particular radioactivity was observed in CaWO4 ({alpha} active 180W), CdWO4 ({beta} active 113Cd, 2v2{beta} decay of 116Cd, 180W), and GSO ({alpha} active 152Gd) detectors. The radioactive contamination of the studied scintillation crystals is compared with that of commonly used detectors. |
