SAWIDIS, T., and HEINRICH, G. 1992. Cesium-137 monitoring using lichens and mosses from northern Greece. Can. J. Bot. [140][141][142][143][144]. Cesium-137 content in lichens and mosses from northern Greece was measured for regular periods of time during the 5 years following the Chernobyl reactor accident. A clear increase of the cesium interception was observed for about 2 years after the accident. Later a gradual decrease was detected that depended on the habitat and the collected species. A great variation in values was observed when comparing contamination in all the habitats investigated during the same collecting season.
