Lichens, mosses, higher plants: Following the reactor accident in Chernobyl, the radiocesium ( 137Cs ) activity in the lichen Pseudevernia furfuracea rose to over 50 000 Bq kg-1 d. w. from an initial value of approximately 400 Bq. The biological half-life of 137Cs in lichens and mosses was two to three years. The biological half-life of 90Sr was shorter than that of 137Cs, between 1.2 and 1.6 years. The biological half-life is not a constant value, it is increasing with time. The 137Cs concentrations …
