In a lead fraction isolated from the barites, concentration and isotopic composition of lead were determined by photon activation analysis and ICP MS, respectively. The radioactivity of the radiobarites has been caused solely by 226Ra in surface layers or along cracks younger than 10–15 thousand years.
