Cadmium tungstate crystal scintillators enriched in 106Cd up to 66% (106CdWO4) and 116Cd up to 82% (116CdWO4) have been developed to investigate double beta processes in 106Cd and 116Cd. The metal samples of the enriched cadmium were purified by heating with filtration in combination with distillation through getter filters. The cadmium tungstate compounds were synthesized from solutions by...

Low background purification and growth techniques for liquids and solids
oral presentation
Presently cryogenic liquids are extensively used in experiments looking for
rare nuclear events at low energies, for which the main issue is reduction of background. One of its most important sources may be intrinsic radioactive impurities of the cryogenic gas. A method to investigate properties of the short-lived Rn-222 daughters present in liquid nitrogen will be presented. Since they are...

Water is used in the Borexino Solar Neutrino Experiment as a shielding against external gamma radiation, as well as a medium to be used in purification processes and cleaning of various part of the equipment.
The Borexino Water Purification System uses normal fresh Water (10^-3 Bq/kg of U-238,Th-232,K-40, 0.3 Bq/kg of Ra-226 and 10 Bq/kg of Rn-222) and makes use of various purification...
