“…Despite the low statistics, a good correlation was observed between 222 Rn concentration, gross alpha/beta activities and 226 Ra concentration with the gamma exposition rate for traditional springs (significance better than 0.01). Reinforcing these observations, a significant statistical correlation between 222 Rn concentration on indoor air and outdoor gamma exposition rate was already reported by Llerena et al (2010) in Galicia. However, the statistical significance is soft in the case of bottling plants (significance better than 0.05).…”

“…It can be found everywhere in the Earth's crust and it easily crosses from the ground into the air. According to the literature [1], indoor radon concentrations mostly depend on local geology, hygrometry, meteorological conditions as well as level of ventilation and occupancy [2][3][4]. Radon is an unstable radionuclide that disintegrates through short-lived decay products before eventually reaching the end product of stable lead.…”

(1) Background: Radon concentrations in the environment are generally very low. However, radon concentrations can be high indoors and can cause some serious health issues. The main source of indoor radon (homes, buildings and other residential objects) can be soil under the house, while other sources can be construction materials, groundwater and natural gas. Radon accumulates mainly in the lower levels of the buildings (especially low-ventilated underground levels and basements). (2) Methods: in this paper, we have measured the indoor radon concentrations at 15 locations in various objects (basements and ground floor/1st floor rooms) in the area of northern Croatia. (3) Results: the results show a higher concentration of radon in the basement area in comparison to values measured in the ground floor and first-floor rooms. The arithmetic mean (AM) and geometric mean (GM) of basement rooms were 70.9 ± 38.8 Bq/m3 and 61.2 ± 2.2 Bq/m3 compared to ground floor and first-floor rooms 42.5 ± 30.8 Bq/m3 and 32.8 ± 2.9 Bq/m3, respectively. (4) Conclusions: results obtained (AM and GM values) are within the maximal allowed values (300 Bq/m3) according to the Euroatom Directive. However, there are periods when maximum radon concentration exceeds 300 Bq/m3. Indoor radon concentrations vary with the occupancy of the rooms and it is evident that the ventilation has significant effect on the reduction of concentration.

“…Uranium is present in small proportions (ppm) in almost all rocks and soils of the planet [2]. Galicia Autonomy (Spain) is an area prone to radon gas due to the common presence of granites, a type of rock and soil that has great uranium concentration [3,4].…”

Radon gas is the second leading cause of lung cancer, causing thousands of deaths annually. It can be a problem for people or animals in houses, workplaces, schools or any building. Therefore, its mitigation has become essential to avoid health problems and to prevent radon from interfering in radioactive measurements. This study describes the implementation of radon mitigation systems at a radioactivity laboratory in order to reduce interferences in the different works carried out. A large set of radon concentration samples is obtained from measurements at the laboratory. While several mitigation methods were taken into account, the final applied solution is explained in detail, obtaining thus very good results by reducing the radon concentration by 76%.
