Abstract:
A total of 1242 samples of soil, collected over Greece, during the period May-November 1986, were counted and analysed for 137Cs from Chernobyl fallout. The counting was performed using a NaI detector on-line to a microcomputer, moreover, 252 of the samples were also analysed using Ge detectors, for inter-comparison and also for the assessment of other long-lived isotopes in the fallout. The results show that 137Cs fallout from Chernobyl presents a remarkable geographical variability. The evaluated ground activity due to 137Cs deposition ranges between 0.01 and 137 kBq/m2.
