Abstract:
129I and 36Cl were measured by accelerator mass spectrometry in 11 lichen samples (Parmelia sulcata) collected in 1990 from three regions (Novozybkov, Bragin and Ovruc) near Chernobyl. Previously measured activities of 137Cs were highest in the samples from the Novozybkov region while the measured activities of 36Cl and 129I in this study were highest in the samples from the Bragin region. The regional distribution patterns of the 36Cl and 129I show a positive correlation suggesting that these volatile radionuclides were deposited in the same manner.
