Measurement of the 222Rn background in the DEVIS experiment

In the DEVIS tracking experiment that is being performed at the Institute of Theoretical and Experimental Physics (ITEP, Moscow, Russia) and which is devoted to searches for 136Xe double-beta decay, the 222Rn concentration is measured in xenon samples with different content of the isotope 136Xe. The number of probable double-electron events from 214Bi decay mimicking the double-beta decay of 136Xe is estimated.
