Correlation coefficientsbetween radionuclides were found 0.72 fora weekly period and 0.88 for a monthly period. Thehigh coefficients prove relations between 222 Rn and210Pb in air at the ground level of the atmosphere.The concentrations of 222 Rn and 210 Pb ranged from0.59 to 11.1 Bq.m –3 with average 3.73 ± 0.17 Bq.m –3and from 0.22 to 2.37 mBq.m –3 with average0.83 ± 0.02 mBq.m –3 , respectively. These are typicalvalues of air activity concentrations of 222 Rn and210Pb for the European area [7–9]. The correlationstudy between air concentrations of radionuclidesand meteorological parameters was carried out andshows correlation between temperature and concentrationof radon in summer months.AcknowledgementThe authors acknowledge to the grants of theMinistry of Education of the Slovak Republic(VEGA project No. 1/3046/06, ESF project JPDBA 3 2005/1-034) and Comenius University inBratislava (Grant of Juniors UK/369/2007).REFERENCES1.
