In this study, long-term and continuous monitoring of atmospheric radon concentration, temperature, air pressure, and humidity was conducted at China Jinping Underground Laboratory. The impacts of temperature, humidity, and air pressure on radon concentration in the experimental environment were specifically examined, along with the potential interactions among these factors. Moreover, Radon data were denoised using Singular Spectrum Analysis (SSA) to reveal factors that might influence changes in radon concentration. The possible mechanisms by which these environmental factors influence radon migration have also been explored. This research not only provides new insights into the behavior of radon in underground environments but also offers important references for formulating effective radon management and protective actions.

Since the 1980s, radon has been recognized as a public health concern in Switzerland and internationally. In an effort to more accurately estimate the number of lung cancer cases attributable to radon exposure, Swiss health authorities initiated the creation of radon measurements into a centralized national database. As of 2025, this database comprises approximately 300,000 measurements from 150,000 buildings across the country.

To minimize the occupational radiation hazards for workers in uranium or associated radioactive underground mines, it is necessary to control the radon exposure dose in each branch of the mine ventilation network. Firstly, a mathematical model of determining potential alpha energy concentration (PAEC) of radon daughters in a single branch was proposed on the basis of the previous radon concentration calculation model in the ventilation network considering ventilation pressure drop. Then, two estimation models of radon exposure dose based on the equilibrium radon concentration and PAEC of radon daughters are introduced.

Naturally occurring radioactive gases in soil, such as radon, are recognized for their significant impact on local air quality and potential health risks to nearby populations. The disturbance of the Earth's surface through excavation activities can enhance the release of these gases, increasing the likelihood of radon exposure. This study investigates soil samples collected from various sites across the Halabja governorate in Iraq to provide a comprehensive evaluation of the area's radiological profile.

Radon (Rn), a naturally occurring radioactive gas, is the byproduct of the uranium decay series. As a naturally radioactive gas, radon is frequently used as a geophysical tracer to find underground faults and geological formations, in uranium surveys, and to forecast seismic events. Abnormalities in radon time-series (RTS) data have been studied before seismic events, indicating that it may act as an earthquake precursor.

The natural background radiation to humans comes both from outside the Earth (cosmic radiation) and from radioactive isotopes found on Earth (terrestrial radiation). Radionuclides of terrestrial origin are partly external exposure and partly internal exposure via ingestion and inhalation. One of the most important sources of external terrestrial radiation is soil, where the most significant isotopes found are uranium-238, uranium-235 and thorium-232, members of the decay series, and potassium-40.
