摘要：
Background processes were studied in a proportional drift detector with a volume of 300 liters intended for the search for 2beta-decay of Xe-136. A technique is developed for the selection of background events associated with U-238-series isotopes entering the detector from the gas purification system because of diffusion of Rn-222. The technique allows the registration of Rn-222 impurities with a relative concentration of 10(-20)-10(-21) in working gas. For an exposure of 418 h, the lower limit of the half-life time is found (T1/2(2beta2nu) > 9.3 . 10(19) yr) with a confidence level of 90%.
