Continual monitoring of radon activity concentration was performed in two caves: Domica and Važecká. Radon in the air of the Domica cave was monitored from June 2010 to July 2011. Radon research in the Važecká cave started in June 2012 and it is still being carried out. Radon concentration in cave atmosphere exhibited seasonal, short-term and daily variations. Daily average of radon in Domica varied from 0.5 to 2.7 kBq m(-3). Seasonal trend was characterised by the highest concentration in September and the lowest from February to March. Radon concentration in the Važecká cave was significantly higher, and the daily average ranged from 1.0 to 5.3 kBq m(-3). The highest values were registered from June to September and in January. The seasonal and daily variations of 222Rn activity concentration in the atmosphere of both caves are assumed to be associated with the atmospheric temperature. No effect of atmospheric pressure on radon short-term variation was found.
在多米察（Domica）和瓦热茨卡（Važecká）两个洞穴中对氡活度浓度进行了持续监测。多米察洞穴空气中的氡从2010年6月至2011年7月进行监测。瓦热茨卡洞穴的氡研究始于2012年6月，目前仍在进行。洞穴大气中的氡浓度呈现出季节性、短期和每日变化。多米察洞穴氡的日平均值在0.5至2.7 kBq m(-3)之间变化。季节性趋势的特点是9月浓度最高，2月至3月浓度最低。瓦热茨卡洞穴中的氡浓度明显更高，日平均值在1.0至5.3 kBq m(-3)之间。最高值出现在6月至9月以及1月。两个洞穴大气中222Rn活度浓度的季节性和每日变化被认为与大气温度有关。未发现大气压力对氡短期变化有影响。
