The level of radioactive contamination of the 106CdWO4 scintillator by isotopes of U/Th radioactive families. In addition, the half-life of 150Nd to the first 0+ excited state of the daughter nucleus has been set on the level of T1/2 = 4.7_(-1.9 + 4.1) (stat.) ± 0.5 (syst.) * 10^19 years, which is in a good agreement with the results of previous experiments. The activity of 176Lu and 138La in the sample was determined at the level of 0.29 ± 0.04 mBq / kg and 0.057 ± 0.009 mBq / kg, respectively. Also, the upper limits for the activity of radioactive contamination of the sample by 40K (1.8 mBq / kg), 137Cs (0.04 mBq / kg) and U/Th daughters have been set on the level (0.3 - 5.4) mBq / kg (with a confidence level of 90%).
