Abstract
Measurements of gross beta activity and 3H concentration of firn samples from different regions can be used to determine environmental contamination by radioactive fallout from nuclear weapons tests in the atmosphere since 1952. The exposure dose to the population due to radioactive fission products in the drinking water supply from glacierized areas is compared to maximum acceptable concentrations derived from ICRP annual limits of intake (ALI). It is shown that even from heavily contaminated layers the risk to the population is acceptable.
