“…Lichens have been reported to accumulate stable and radioactive elements (Tuominen 1967, Larsson 1970, Eriimetsii & Yliruokanen 1971, Tuominen & Jaakola 1973, Garty et al 1977. Especially the long-lived radionuclides '"Cs, "'Sr, '"Pu and '"'Pb were subject to numerous investigations in subarctic ecosystems and were found t o contribute significantly to the radiation burden of people living on reindeer (caribou) meat via the lichenreindeer (caribou) -man food chain (Hanson et al 1966, Kauranen & Miettinen 1969, Hanson 1971, Persson 1973, Holm & Persson 1975, Rahola & Miettinen 1977.…”

Regions of elevated natural radioactivity (Gastein–valley, Waldviertel) were compared to regions of low natural radioactivity (surroundings of Salzburg City). The natural radionuclides 238U, 40K and 7Be and the man–made nuclides 137Cs, 144Ce, 95Ze95Nb were measured by gamma ray spectrometry. No statistically significant difference was found between samples of the Gastein–valley, Waldviertel, Salzburg, Grossarl and Dachstein concerning the content of natural radionuclides. The amount of the short–lived fission products 144Ce, 95Zr–95Nb as well as of the natural 7Be increased with altitude. The specific nuclide concentration varies with species but was almost independent of growth form and substrate.
