摘要：

The plutonium concentrations of fuel peat samples from southern and central Finland were analyzed. The same samples had previously gone through gamma-spectrometric analysis, in which the detected nuclides could be divided into two groups by calculating correlations between activities: the volatile Cs-I group and the non-volatile Ce-Zr group. The plutonium of Chernobyl origin correlates rather well with the non-volatile group and not at all with the volatile group. The volatile group comprises the nuclides Cs-137, s-134, I-131 and Te-132, and the non-volatile group Zr-95, Ce-141 and Chernobyl-Pu.
