Abstract: The Cs-134/137 activities were measured from different tree organs of spruce, larch and sycamore maple. Two locations in South Bavaria were monitored during a period of 2.5 years following the Chernobyl accident. Samples taken in 1985 allow to determine the Cs-137 contamination before the accident. Increasing Cs-137 activities from older to younger needle years ofPicea abies caused by root-uptake of the global weapons’ fallout are due to the high phloem mobility of this element and the remaining of the needles at the tree for about 6–7 years.
