摘要

The radon concentration was measured in soil and water samples from an active landslide zone in the Garhwal Himalaya. The landslide is compound in nature i.e. slump in the crown portion and debris slide in the lower part. The measured radon concentration varies from 3.1 to 18.3 Bq/l in water whereas in soil/debris samples it varies from 2.3 to 12.2 kBq/m~3. The crown portion (upper portion) show higher radon values in comparison to distal portion. The higher radon concentration in crown portion may be because of the failure plane of landslide associated with high fracturing and crushing whereas, increased porosity of debris of slide does not allow radon to accumulate in soil and water in the lower portion.
