Effect of simulated earthquake loading on radon exhalation from uranium tailings dam.

"When an earthquake is simulated on the uranium tailings dam with a shaking table test and the change in radon concentration is determined, it is found that the earthquake causes micro-fissures in the uranium tailings dam, which aggregate to produce fractures. " During the process, the radon concentration will rise sharply, as will the radon exhalation rate. The results show that radon can be used as a tracer to determine uranium tailings dam damage. ".

A comprehensive study of radon in drinking waters of Hanumangarh district and the assessment of resulting dose to local population.

"The average value of radon in surface water varied from 0. 12 to 2. 76 Bq/l, with an average value of 0. 12 to 2. 07 Bq/l and a standard deviation of 2. 24 Bq/l and an average value of 4. 8 Bq/l. " radon in water does not pose a significant radiological health risk to the population of the study area, according to a radon in water study.

Detailed Indoor Radon Survey in Dwellings of Provisional Radon-Prone Areas in Korea.

"The aim of this survey is to determine indoor radon concentrations for 11 counties in Korea, produce a detailed radon distribution map, and analyze the findings by several factors influencing indoor radon levels. " Bq m-3 on the annual average indoor radon concentration for the survey areas had a geometric mean of 94 BQ m-3, with 6. 6% of all sampled dwellings showing values over 300 Bq m-3. This report can serve as a basis for establishing national radon action plans and a map to additional regional radon surveys. ".

Internal Exposure From Indoor Radon, Thoron and Their Progeny in Residence Around High Background Radiation Area, Phang Nga Province, Thailand.

"Exposure to elevated background radiation levels in the tin mines or active fault zones may raise the risk of lung cancer in the respiratory system when considering the health risks of the immediate residents. " In total, 5. 9 mSv were estimated to be 3. 0-4. 6, 2. 5-3. 7, and 0. 4-1. 0 mSv, respectively, as the ICRP's new dose conversion factors.

Evaluation of soil-gas radon concentrations from different geological units with varying strata in a crystalline basement complex of southwestern Nigeria.

"The aim of this research is to determine the difference in soil-gas radon concentrations from various rock formations in Ogbomoso, southwestern N. . . . ia. " With respect to depth, radon concentrations at five geological domains in Ogbomoso are determined with respect to depth. Based on the International Commission on Radiological Protection's recommendation, Ogbomoso's overall soil-gas radon concentrations increased from 0. 06 to 26. 5 kBq/m 3 in Ogbomoso, the highest in the natural range of 0. 4 to 40 kBq/m 3. An F-ratio of 6. 989 and a p-value of 0. 001 were obtained for the first inferential hypothesis, with a p-value of 0. 076 expected for the second inferential hypothesis using ANOVA tests. At 80 cm and level 0 at other depths, the pollution index in Ogbomoso is at level 1 at 80 cm and level 0 at other levels. ".

Anti-motion blur single-pixel imaging with calibrated radon spectrum.

"Single-pixel imaging, a new computational imaging method that has flourished in the last decade, can accurately capture the image of a static object by stringently measuring light intensities from it. However, when SPI is used to photograph the dynamic object, intense motion blur in the restored image tends to appear. In addition, the new design can also be used for fast object tracking. ".

Application of radon ( 222 Rn) as an environmental tracer in hydrogeological and geological investigations: An overview.

"Radon is made in the crystal lattice of the minerals and emanates out by alpha recoil. " This paper discusses state-of-the-art methods for measuring dissolved radon in water and its potential use as a tracing and precursor in a variety of hydrogeological and geological fields, including the investigation of lake and submarine groundwater interactions, geological mapping, submarine groundwater discharge, and submersion of waters, geochemical explorations, and environmental investigations, among other hydrogeological and geological uses, such as determining submersion relationships, sedimentation of sedimentation -based radon based methods have been shown to be more reliable in the water resources domain than seismic precursory studies, among the many applications. The results, which were based on a radon review in the above applications, will lead to improved understanding of the hydrologic processes, and thus, support the engineers and water managers for the efficient development and management of water resources.

Analysis of Radon Measurements in Relation to Daily Seismic Activity Rates in the Vrancea Region, Romania.

"The aim of this research is to look at the correlation between radon measurements and the daily seismic activity rate in order to determine the seismic activity rate using sole radon measurements. " The discrete wavelet transform has been used to analyze the radon signal at two different scales: long and short periods. From the research's long-period perspective, an approximate linear relationship was found between the radon series and the daily seismic activity rate, providing insight into the seismic activity in the study region with only the radon data. The findings from this area suggest that the radon time series analysis will be an effective complement to traditional seismic analysis used in operational earthquake forecasting. ".

Characterization of Colorado residents and radon reduction behaviors through latent class analysis and path models.

"Within the United States, state-level radon reduction efforts rely on education and outreach to inspire people to test and reduce their home. " This report examines the 2012 Behavioral Risk Factors Surveillance System in Colorado to identify distinct groups of people using Latent Class Analysis, as well as comparisons between radon measurement methods to determine the underlying causes of radon reduction patterns using path models. Responding to radon survey results revealed significant differences across age groups, with Struggling Young Families being the least likely to be aware of radon, having tested their home for radon, and having their house minimized. The findings from this study can be used to refine future radon reduction policies and legislative policies to raise equity of radon reduction activities while still ensuring radon mitigation takes place in rental properties.

Multi-level continuous monitoring of indoor radon activity.

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