A review is given of fall-out monitoring in Norway during 1959. It appears that the mean residence time in the stratosphere of fall-out materials from 1958 weapons tests may be about 6 months or less, instead of 5 years or more as previously assumed. The deposition of short- and longlived isotopes during the first 6 months of 1959 was higher than during previous years. Concentrations of fall-out materials in air and precipitation have since decreased and are now the lowest for many years. Estimates show that between October 1958 and October 1959 external radiation has probably given larger bone marrow and gonad doses than internal Sr-90 and Cs-137 radiation. (auth)
