Abstract: Gross-beta-activity of snow samples from 10 vertical profiles was measured with respect to their contamination by fallout from the Chernobyl reactor accident. Samples were collected on Kesselwandferner (Ötztal Alps, Austria) in the years 1986, 1987 and 1988. Peak activity concentrations decrease from >100 Bq/kg (1986) to <10 Bq/kg (1988), however, a dispersion of the contaminated range to depths of about 11 m is observed, while the contamination per unit area remained almost constant. With gamma-spectroscopy the isotopes 137Cs and 134Cs were detected as dominant.
