摘要：

Small single crystals of CdWO4 were irradiated by Co-60 gamma-rays for accumulated doses in the range of 10(4) to 10(8) rad. Degradation in optical transmittance was less than 2%/cm for doses up to 10(8) rad when the measurement was carried out a few to several tens of hours after irradiation. The result is discussed in comparison with the larger damage reported previously. The intrinsic background spectrum indicates that there are much less radioactive impurities in CdWO4 than in GSO:Ce and BGO.
