Seaward, MRD/ Heslop, JA/ Green, D/ Bylinska, EA 1988: Recent levels of radionuclides in lichens from southwest Poland with particular reference to 134Cs and 137Cs. - Journal of Environmental Radioactivity7: 123-129. [RLL List # 135 / Rec.# 16867] Keywords: RADIONUCLIDES/ POLAND/ CESIUM/ UMBILICARIA/ CHERNOBYL/ USSR
Abstract: 2 tables. 2 figures. [Recent significant increases in 134Cs and 137Cs have been found in Umbilicaria species when compared to studies in 1978-79. "The composition and ratio of the various radionuclides, particularly in respect of 134Cs and 137Cs, exhibit a characteristic signature consistent with contamination derived from the accident at Chernobyl nuclear reactor in April 1986."]
