222Rn and 220Rn Levels in Drinking Water, the Related Health Implications, and Influencing Environmental Parameters in the Volcanic Area of Nkongsamba, Cameroon

Applied and Environmental Soil Science, Volume 2026, Issue 1, 2026.
Radon (222Rn) and thoron (220Rn), both naturally occurring radioactive gases, are significant contributors to radiation exposure, posing risks such as lung and stomach cancer. This study assesses radon and thoron concentrations in drinking water sources within the volcanic region of Nkongsamba, Cameroon.

Assessment of Indoor Radon Exposure Risks in Relation to Dwelling Types in Gold‐Mining Communities of Akyempim, Wassa East District, Ghana

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 ...

Comparative Assessment of Seasonal 222Rn Variations in Indoor and Underground Spaces With Emphasis on Correction Factors

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.

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.

Gamma‐Ray Spectrometry of Soil Samples From a Pilot Site of Uranium Anomaly in the Sahel Region of Burkina Faso

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 ...

Thoron emanation and exhalation of Slovenian soils determined by a PIC detector-equipped radon monitor [PDF]

, 2016
The health risk from thoron (Rn-220) is usually ignored owing to its short half-life (55.6 s), but the generated thoron decay products can cause a significant dose contribution.

Gradient chamber for measuring the exhalation rate of radon and thoron from surfaces

Scientific Reports
A novel instrument (gradient chamber) and method for measuring the exhalation rates of radon (²²²Rn) and thoron (²²⁰Rn) from surfaces (e.g., soil, rocks, building materials) have been developed and tested. Determining radon and thoron exhalation rates is
