New Applications in Gas Geochemistry
Geofluids, Volume 2020, Issue 1, 2020., 2020 Gases present in the Earth crust are important in various branches of human activities. Hydrocarbons are a significant energy resource, helium is applied in many high‐tech instruments, and studies of crustal gas dynamics provide insight in the geodynamic processes and help monitor seismic and volcanic hazards.

Indoor Air, Volume 2026, Issue 1, 2026.This study investigated the effects of dwelling type, wall and floor coverings, radium‐226 concentration, soil moisture, and radon exhalation on indoor radon‐222 levels in the gold‐mining community of Akyempim, Ghana. Indoor radon was monitored using CR‐39 solid‐state nuclear track detectors deployed in 144 rooms across 21 sites for 90 days ...

Indoor Air, Volume 2025, Issue 1, 2025.Exposure to radon‐222 (222Rn) and its decay products poses a significant public health risk. 222Rn tends to accumulate in poorly ventilated areas, underground spaces, and caves, which justifies the existence of international reference levels for its annual average indoor concentrations.

Simultaneous Measurements of Radon and Thoron Exhalation Rates and Comparison with Values Calculated by UNSCEAR Equation [PDF]
Journal of Radiation Research, 2009 We simultaneously measured radon and thoron exhalation rates in areas of weathered acid rocks in Japan to investigate the relationship between them and between measured and calculated radon exhalation rates. To calculate the radon exhalation rate, we used an equation proposed by UNSCEAR.

Exploring Seasonal Variation of Indoor Radon in Campania: Preliminary Findings
Indoor Air, Volume 2025, Issue 1, 2025.This study focuses on the indoor radon gas monitoring in 30 residences in Campania to evaluate seasonal variability. Approximately 570 CR‐39 solid‐state detectors were employed. Measurements were taken monthly, quarterly, semiannually, and annually, starting in October 2022 and ending in September 2023.

Applied and Environmental Soil Science, Volume 2024, Issue 1, 2024.The natural radioactivity level has been determined in a pilot site located at Solhan, in the Sahel region of Burkina Faso by means of gamma‐ray spectrometry in soil samples collected at a depth of 40 cm. The activity concentrations are estimated for 238U (range from 181.89 ± 3.62 to 191.37 ± 3.71 Bq·kg−1), 232Th (range from 44.92 ± 2.96 to 48.40 ± 3 ...
