title: Different approaches for estimating the deposition of radiocaesium on mountain pasture in southern Norway.
abstract: Different approaches to the estimation of radiocaesium deposition on different types of indigenous mountain pastures have been examined. In situ gamma spectrometric measurements performed using a portable multi-channel analyser (3 x 3 in Nal detector) with the detector placed on the ground, on a tripod at a height of 100 cm above the ground or fastened to a rucksack frame 90 cm above the ground were compared with conventional soil sampling. Field gamma-ray measurements in connection with soil sampling appear to be a promising tool for estimates of deposition on mineral soils in areas with different topography and vegetation.
