Daily and seasonal radon variability in the underground low-background laboratory in Belgrade, Serbia

Abstract: Radon time-series analysis, based on the short-term indoor radon measurements performed worldwide, shows two main periodicity: daily and seasonal. The information obtained from time series of the measured radon values is the results of the complex radon dynamics that arises from the influence of the large number of different parameters (the state of the indoor atmosphere (temperature, pressure and relative humidity, aerosol concentration), the exchange rate between indoor and outdoor air and so on). In this pa… Show more

“…In addition, the difference between the inside and outside temperature of the building is plotted. With every increase of the temperature difference an increase of the radon emission rate occurred, a similar behaviour that has been observed in [9] based on measurements of the radon concentration. A possible explanation of this effect could be that warm air from inside escaped through leaks in the attic and produced a negative pressure which forced the radon to exhale from the ground.…”

“…Also, the results show very low radon level on the fi rst fl oor (well below the outdoor values) in the apartment. In such sense, we performed test intercomparison radon measurements for two active devices SN1029 and SN1030 in well-defi ned and controlled radon atmosphere (radon concentration below 30 Bqm -3 ) in the Underground Low-background Laboratory in the Institute of Physics Belgrade [17,18]. Additional testing includes the same place and time of the measurements but different sampling time set to 1, 2, 4, 8 and 12 h. The results are shown in Table 3.…”

“…Anyway, in this case study, it is possible to exclude the influence of the configuration of the monitoring station and the type of detector since these are identical in the four sites. The annual and semiannual cycles on radon signals have been correlated to the annual variation of the climatic variables (mainly the temperature) in relation to the solar annual and solar semiannual cycles (∼⃒365.2 and ∼⃒180 days and the lunar cycle ∼⃒29.5 days) (İnan et al., 2012; Udovičić et al., 2014). The occurrence of the same cycles in the cross‐wavelet power spectra of radon and the three climatic variables would confirm the direct relationships between radon and temperature.…”
