DESCRIPTION:Speakers: Valery Kuzminov (INR RAS)\nDescription of the TAU-4 
 installation intended for long-term monitoring of the half-life value T1/2
  of the 212Ро is presented. Natural thorium used as a source of the moth
 er’s chain. The methods of measurement and processing of collected data 
 are reported. Short testing measurements were made in the ground building 
 (680 hours) and underground laboratory (564 hours). Averaged value T1/2=29
 4.09±0.07 ns of the 212Po half-life was found for the ground level data s
 et similar one for the underground data set.  The solar-daily variations w
 ith amplitudes ASo=(11.7±5.2)∙10-4 for the ground data and  ASo=(7.5±5
 .3)∙10-4 for the underground one  were found in a series of τ values.\n
