"The amount of radon in surface water varied from 0. 12 to 2. 07 Bq/l with an average of 0. 62 Bq/l and a maximum deviation of 2. 24 Bq/l, with an average value of 0. 61 Bq/l and a standard deviation of 2. 74 Bq/l. " It can be said that radon in water poses no significant radiological health risk to the population of the study area. ".

"The aim of this study was to establish indoor radon concentrations for 11 counties in Korea, create a detailed radon distribution chart, and compare the findings by various factors that influence indoor radon levels. " 94 Bq m-3 in the survey areas had a geometric mean indoor radon concentration of 94 Bq m-3, with 6. 6% of all sampled dwellings showing values over 300 Bq m-3. This report can be used to develop national radon action plans and guide for new national radon survey" in various regions.

"The purpose of this study is to investigate the correlation between radon measurements and the daily seismic activity rate, as well as a method that allows estimation of the seismic activity rate using only radon measurements. " From the analysis, which was conducted on a long-period basis, an approximate linear relationship between the radon series and the daily seismic activity rate has been found, providing insight into the seismic activity in the study area that has only the radon data. The findings from this area show that the radon time series's investigation may be an excellent complement to conventional seismic analysis used in operational earthquake forecasting.

"A passively integrating discriminative radon-thoron monitor and a radon-thoron probe and a radon-thoron progeny monitor were used to determine indoor radon, thoron and their progeny concentrations in urban areas along the old mines of southern Thailand's old mines. " When considering the health risks of the local residents, exposing to high background radiation levels in natural 238U and 232Th in the tin mine areas or active fault areas can raise the risk of lung cancer in the respiratory system.

"The aim of this research is to determine the variation of soil-gas radon concentrations from various rock formations in Ogbomoso, southwestern N. . . . ia. " With respect to depth, radon concentrations at five different geological domains in Ogbomoso are determined by depth. For the first inferential hypothesis, an F-ratio of 6. 989 and a p-value of 0. 001 were established, with an F-ratio of 2. 489 and a p-value of 0. 076, while the second inferential hypothesis using ANOVA techniques was found. At other depths, the pollution level in Ogbomoso is at level 1 at 80 cm and level 0 at other levels. In order to have a sustainable city, cracks that could act as a route for indoor radon on the floors of the buildings around the polluted zones should be avoided.

"Radon is manufactured in the mineral crystal lattice of the minerals and emerges out by alpha recoil. " This paper discusses the state-of-the-art methods used in several hydrogeological and geological applications, including measuring dissolved radon in water and its potential uses as a tracer and precursor, submarine Groundwater Discharge estimation, geochemical mapping, submarine characterization, and NAPL contamination studies, among others. radon-based methods have been shown to be more reliable in the water resources domain than seismic precursory ones, among the many applications. The results, which were based on a radon review in the above applications, will lead to a better understanding of the hydrological processes and, thus, help the engineers and water managers for the sustainable development and management of water resources.

"Within the United States, state-level radon reduction efforts rely on education and outreach to inspire people to test and minimize their home. " About 5% of the housing units in Colorado, United States, have been tested for radon. This report examines the 2012 Behavioral Risk Factors Surveillance System in Colorado to identify discrete groups of individuals using Latent Class Analysis, and compares radon identification, measurement, and mitigation to determine the root causes of radon reduction behaviors using path models to determine the truth of radon reduction habits. The least likely to be aware of radon, have tested their house for radon, and have their home minimized were among the many groups surveyed by radon survey respondents. "The findings from this research can be used to refine existing radon reduction policies and legislative initiatives to increase equity of radon reduction activities while still ensuring radon mitigation takes place in rental properties.

"The calibrations of various batches of activated charcoal used in various canister styles are usually carried out in large volume controlled environmental chambers with known and controlled radon concentration, temperature, and humidity. " If canisters could be accurately calibrated and pass quality inspection in less controlled environments, Radon screening could be facilitated in areas lacking ready access to environmental chambers. This report compares charcoal canister calibrations from a highly controlled radon chamber with calibrations from a basement storage area subjected to temporally variable radon. To determine limits on how stable radon must be in a space for equilibrium-based calibration, a digital simulation of charcoal canister kinetics was also carried out. Overall, the results of measurements using calibrations from each space differed by less than 10% after 2 d exposure time, demonstrating that meticulously controlled conditions are not necessary for the accurate calibration of charcoal canisters.

"Collecting more than three years of radon concentration data helps us to find trends on both short and seasonal scales as well as determining the relationship between radon variations and changes of internal temperature and relative humidity. " Additionally, continuous radon monitoring at various levels of the building provides a unique opportunity to track vertical radon transport, allowing for a first-order estimate of upward radon velocity.

"The buildup of the radioactive gas radon in closed environments, such as dwellings, is the result of a very diverse sequence of events related to the presence of different sources. " In this paper, an application on a new experimental site was carried out in order to determine the model's adaptability to various house typologies and environmental contexts. The model's activities were determined using a portable radon detector and findings, showing again good results of the device. ".
