Distribution of 137Cs activity concentration in wood scots pine (Pinus sylvestris L.) of Zhytomyr Polissya after the Chernobyl accident
Using the calculated values for wood samples (relative diameter, height and relative activity concentration of 137Cs) selected in different parts of the profile tree stems, statistical and graphical interpretation of the regularity of the distribution of 137Cs in the wood of model trees of Scots pin...
