Аннотация:Abnormal High Radon Exhalation Levels on the Mount
Beshtau, North Caucasus
Abstract. The measurements of radon exhalation rate, radon concentration in the air, gammadoze rate and radium content in soils on the Mount Beshtau were carried out. The very high radon levels were discovered in local zone on the western slope. The radon exhalation rate in the anomalous zone achieves 15,000 mBq/m2
s, and the radon concentration in the atmospheric
air exceeds 4000 Bq/m3. These levels sufficiently exceed the local background. The extremely
high values of radon exhalation rate in the anomalous zone cannot be explained by local
sources of radon. Anomalous levels of radon exhalation probably result from radon transport
out of fracturing zones with convective air flows.
