Concentration of 14C in tree rings from Plitvice National Park region

14C concentration of the organic matter of an individual tree ring reflects environmental radioactivitz of the zear of its growth. For our 14C analysis we used fifty years old fir tree from Plitvice National Park region. Our results show an excellent agreement with those obtained from a spruce tree felled at Matra region and an acacia tree felled near Debrecen, both from Hungary. Comparison with atmospheric 14C concentration shows also a very good agreement.
