Abstract

In view of the lower radionuclide activities of moss and lichen, tree barks can be used as biomonitors of radioactive contamination, regardless of the contribution of soil uptake. The present study was conducted to determine the activity concentrations of (137)Cs, (40)K, (232)Th and (238)U in the barks of pine (Pinus mgra) and oak (Quercus petraea) trees collected from the Thrace region in Turkey By considering the previous studies carried out in the same region, it is noticed that among lichen, moss, oak bark and pine bark, oak bark is the best accumulator of (137)Cs and natural radionuclides.
