“…It has an expected pattern, lowest in summer and highest in autumn, winter and spring. Seasonal variation of radon in kindergartens is less than in residential homes [18,22,23]. In Hungary the mechanical ventilation is not typical, such as e.g.…”

“…Selection of the studied kindergartens based on the previous indoor radon [18,19] and geogenic radon potential [20] surveys. The kindergartens closest to the locations, where the highest soil gas radon activity concentration or geogenic radon potential or indoor radon concentration in dwellings was determined, were selected.…”

“…Several studies in Hungary dealt with radon measurements and dose assessment in indoor places like residential homes, public places (hospital, libraries, temples, schools and kindergartens), workplaces, caves, mines, wine cellars. But only a few measurements were performed in kindergartens and the kindergarten data were not published separately from other indoor data [17,18]. However, it is well known that children are one of the most sensitive to all kinds of harm, including ionizing radiation.…”

Annual average indoor radon activity concentration was studied in 88 Hungarian kindergartens in 76 towns of 10 different counties. Annual average indoor radon activity concentration in the kindergartens was 61 Bq m− 3, maximum was 160 Bq m− 3. In the kindergartens the seasonal variation of radon is not so strong like in dwellings, because of the permanent ventilation and the closed period during the summer break.

“…Furthermore, there were measurements of radon and thoron in dwellings within joint projects in the Visegrad countries (Poland, Slovakia, Czech Republic, and Hungary). These were carried out in 156 buildings, including homes and workplaces [17,18] and kindergartens [19]. During these surveys, an old evaluation system was used for the measurements, which was very slow and obsolete as it was based on the visual counting of tracks through a microscope.…”

AbstractAccording to the new European Union Basic Safety Standards (EU-BSS), preparation of the National Radon Action Plan is obligatory for the Member States. One of the plan’s aims is to carry out an indoor radon survey to identify radon-prone areas. In the radon surveys, track detector methods are used. At the University of Pannonia (Veszprém, Hungary), a new scanner-based detector evaluation system has been developed. For the application of the new system, the selection of appropriate parameters is necessary. In this study, selection of the applied track detectors and setting of the etching conditions have been carried out. Two different types of allyl diglycol carbonate (ADC or CR-39) track detectors were investigated, taking into account the detector’s background and response during the exposure (determination of calibration factor). The Baryotrak’s background track density (0–1.5 tracks mm−2) was lower than that of the 0.8–4 tracks mm−2. The response of the Tastrak was higher, but the deviation of the calibration factor was much higher (1.2–5.3 × 10−3 tracks mm−2/(Bq day m−3)) than in the case of the Baryotrak (1.4–2.8 × 10−3 tracks mm−2/(Bq day m−3)). After the systematic review of the etching system, a new method was developed. For the determination of the optimal track diameter, the argon fluoride (ArF) laser was applied to create tracks with diameters in the range of 10–100 μm. The optimum track size was in the range of 40–60 μm. On this basis, new etching conditions were determined: 6.25 M NaOH solution, a temperature of 90°C, and time period of 8 hours.

“…Hungarian law mandates that a national action plan is to be created and put in place to mitigate the health effects of concentrations of radon and daughter nuclide for residential buildings, if these concentrations reach a yearly average level of 300 Bq/m 3 (Decree 487/2015). Based on the above, numerous groups have started research on the effects of indoor air quality, specifically the occurrence and effects of radon (Hussein et al 2013;Nikolopoulos 2014b;Müllerová et al 2016;Vasilyev, Yarmosheenko 2016).…”

The most significant factors of indoor air quality – besides temperature and humidity – are the concentrations of carbon-dioxide (CO2) and radon (222Rn). Radon seepage is caused by and affected by the materials used in walls and floors, the quality of insulation, cracks and even the amount of pipes running through the walls. The amount of CO2 is predominantly affected by the biological processes of the inhabitants, and possibly by potentially faulty HVAC systems. The energy efficiency related upgrades to family homes, which often only extend to window replacements and better insulation have a significant effect and could potentially increase concentrations of both radon and CO2 which has a significant effect on the well-being of the inhabitants. Our tests conducted in Hungary have proven that by using automated heat recovery ventilation (HRV) both energy efficient operation and low concentrations of radon and CO2 are achievable. Our results prove the significance and prevalence of the issue of higher concentrations of these pollutants, and offer a viable solution.
