  1. Unusually high indoor radon concentrations.

    Article - En anglais

    Measurements of indoor radon concentrations in the village Umhausen (2600 inhabitants, Otztal valley, Tyrol, Austria) revealed unusually high indoor radon concentrations up to 274,000 Bq m-3.

    The medians measured on the basements were 3750 Bq m-3 in winter and 361 Bq m-3 in summer, those on the ground floors were 1180 Bq m-3 and 210 Bq m-3, respectively.

    Seventy-one per cent of the houses showed basement radon concentrations above the Austrian action level of 400 Bq m-3 in winter, 33% in summer.

    There are indications that the high radon concentrations are due to a giant rock slide about 8700 years ago.
