22. Conclusion The values of the result of taken samples from Central Aran zone for water samples change in 226 Ra (0,95Bk/l-0,14Bk/l), 228Ra (0,03Bk/l- 0,39Bk/l), 40K (5,6Bk/l-12,5Bk/l), 137Cs (0,18Bk/l-0,45Bk/l), 210Pb (0,13Bk/l-0,9Bk/l), 7Be (11,2Bk/l-17,2Bk/l), for soil samples 226 Ra (17,1Bk/kg-38,5Bk/kg), 228Ra (13,6Bk/kg-36,4Bk/kg), 40K (293Bk/kg- 609Bk/kg), 137Cs (0,22Bk/k5,2Bk/kg), 210Pb (3,2Bk/kg-80Bk/kg), 7Be (0,35Bk/kg-17Bk/kg) this range. When comparing these figures with international and national standards is within the norm, as can be seen, it does not pose any danger for human health and the environment (fauna, flora). Analyzes were carried ait by mean of the gamma-spectrometric device.
