“…4). Radon concentrations are highest in the late winter and early spring, a period characterized by relatively wet, unstable weather, and are lowest in the fall, a season with typically dry, stable weather [12][13][14]. Correlation is seen clearly in comparison of monthly average radon concentration and temperature, humidity and pressure (Fig.…”

The production of 222 Rn depends on the activity concentrations of 226 Ra in the earth's crust, in soil, rock and water. Radon concentration levels are strongly affected by atmospheric influences such as rainfall, real humidity, temperature and barometric pressure, rather than by chemical processes, as it is an inert gas. In particular the exhalation of radon is positively correlated with moisture content, temperature and negatively with pressure, so that these factors must be considered in the determination of exhalation rates in environmental measurements. In this study, radon concentrations in soil gas were continuously monitored for nine months in ten minutes periods, using AlphaGUARD system and the fluctuations of radon concentration were compared with the regional meteorologic data, using time graphs.

People generally spend more than 90% of their time indoors. Exposure to radon in indoor environments can be a significant health problem. In this study, radon concentrations were measured to evaluate the health risks of employees and students in 6 faculty buildings in Afyon Kocatepe University Ahmet Necdet Sezer Campus and to calculate annual effective dose equivalents. Measurements were carried out in the Genitron AlphaGUARD PQ2000 PRO Radon Detector System which measures with active measurement method. The radon concentration values of the faculty buildings are 4.48-82.00 Bqm-3; mean radon concentrations were determined in the range of 20.64-30.91 Bqm-3. The average radon concentration of all buildings was calculated as 24.79 Bqm-3. The annual effective dose equivalents of 6 faculty buildings were determined in the range of 0.16-0.24 mSvy-1, and the average annual effective dose equivalent was calculated as 0.20 mSvy-1. The results were compared with the limit values recommended by the International Commission on Radiological Protection (ICRP) and the Turkish Atomic Energy Authority (TAEK) for radon gas concentrations in indoor environments. The measurement results of the radon concentrations and annual effective dose equivalents of the 6 faculty buildings on the ANS Campus were determined below the limit values allowed by the institutions.

“…The variability of radon exposure indicate that it is affected by several factors such as soil temperature and permeability [13,14], air temperature and pressure difference inside and outside of buildings [15][16][17][18][19][20], and construction materials used for buildings and the ventilation degree of closed environments [21][22][23][24][25][26]. Moreover, some studies have also pointed out that indoor radon levels vary significantly on a daily and seasonal basis [27][28][29][30][31][32][33].…”

It is commonly known that people are exposed to radon and its progenies since they spend about 35% of daytime at workplaces. This exposure has been reported to be more than 50% of the natural radiation. Therefore, determination of indoor radon concentration has been widely conducted by the scientists. This work presents indoor radon measurements and the associated annual dose equivalents obtained in 28 public buildings of the Afyonkarahisar province. The survey was conducted using passive nuclear track detectors and repeated quarterly during a year. The investigation focused on the seasonal and regional effects in indoor radon concentration anomalies. The measured values ranged from 13 Bq.m-3 to 1,932 Bq.m-3 , whereas the calculated average values were in the range of 21.75 Bq.m-3 and 1,032.50 Bq.m-3. Moreover, the mean indoor radon concentration and the corresponding annual dose equivalent values were obtained as 158.8313.16 Bq.m-3 and 1.250.10 mSv.y-1 , respectively.
