“…The study sample, though limited, included both dwellings and workplaces. The average radon concentration, according to this study, was 215 AE 20 Bq/m 3 , about four times that estimated for the whole region (52 AE 2 Bq/m 3 ) in the national survey for dwellings (Bochicchio et al, 2005). Moreover this study highlighted the fact that schools exhibited higher radon levels than other types of workplaces.…”

“…As regards other schools, in 5% of schools radon values ranged between 400 and 500 Bq/m 3 , with 7% of schools exceeding the national action level. The value of the arithmetic mean found in schools located in the province Lecce (209 AE 9 Bq/m 3 ) is very high compared with the regional average (Apulia, 52 AE 2 Bq/m 3 ), as estimated in the national survey on dwellings (Bochicchio et al, 2005). This phenomenon may be due to at least two reasons:…”

“…Radon concentration is found to be higher in the cold period (autumn þ winter) than in the hot period (spring þ summer), which is in agreement with other findings. The relation (autumn þ winter)/(spring þ summer) follows a lognormal distribution with a median of 0.93 and a GSD of 1.5 (Bochicchio et al, 2005;Kullab et al, 2001;Papaefthymiou et al, 2003;Singh et al, 2005). However, the statistical significance of such a result was not considered strong enough to determine whether the seasonal behaviour was masked by other particular weather conditions.…”

“…In the current British (3,6) , Irish (7) and French (8) studies, the seasonality factors are 1.30 for the coldest winter months and 0.70 for midsummer. In the extensive Italian study with 4742 houses the geometric mean of the winter/summer ratio was 1.23 (geometric standard deviation, GSD 1.71) (9) . In the Italian study two 6-months measurements were carried out.…”

The effect of soil moisture on seasonal variation in soil air and indoor radon is studied. A brief review of the theory of the effect of soil moisture on soil air radon has been presented. The theoretical estimates, together with soil moisture measurements over a period of 10 y, indicate that variation in soil moisture evidently is an important factor affecting the seasonal variation in soil air radon concentration. Partitioning of radon gas between the water and air fractions of soil pores is the main factor increasing soil air radon concentration. On two example test sites, the relative standard deviation of the calculated monthly average soil air radon concentration was 17 and 26 %. Increased soil moisture in autumn and spring, after the snowmelt, increases soil gas radon concentrations by 10-20 %. In February and March, the soil gas radon concentration is in its minimum. Soil temperature is also an important factor. High soil temperature in summer increased the calculated soil gas radon concentration by 14 %, compared with winter values. The monthly indoor radon measurements over period of 1 y in 326 Finnish houses are presented and compared with the modelling results. The model takes into account radon entry, climate and air exchange. The measured radon concentrations in autumn and spring were higher than expected and it can be explained by the seasonal variation in the soil moisture. The variation in soil moisture is a potential factor affecting markedly to the high year-to-year variation in the annual or seasonal average radon concentrations, observed in many radon studies.
