  Cadmium tungstate crystal scintillators enriched in 106Cd and 116Cd were
developed. The produced scintillators exhibit good optical and scintillation
properties, and a low level of radioactive contamination. Experiments to search
for double beta decay of 106Cd and 116Cd are in progress at the Gran Sasso
National Laboratories of the INFN (Italy). Prospects to further improve the
radiopurity of the detectors by recrystallization are discussed.
