Multiple point rapid measurement method for radon exhalation rate in uranium tailings reservoir and its application

四川大学学报. 自然科学版, 2018
Based on the principle of that the equivalent decay constant of perforated accumulation chamber, we propose a new method to rapidly measure the surface radon exhalation rate with multi-point detection technique.

The method for recalibration of thoron concentration reading of RAD7 and obtaining the thoron exhalation rate from soil surface [PDF]

Nuclear Technology and Radiation Protection, 2013
Thoron exhalation rate can be obtained through the combination of the “accumulation chamber” technique and RAD7. Thoron’s rapid decay causes the intake path and the air flow rate to become important factors in calibration.

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.

Efficacy and Safety of Acupuncture for Idiopathic Tinnitus: A Randomized Controlled Clinical Trial

International Journal of Clinical Practice, Volume 2026, Issue 1, 2026.
Objective The present study was designed to evaluate the effects and safety of acupuncture on idiopathic tinnitus. Methods A total of 74 participants (aged 18–60 years) with idiopathic tinnitus were randomly assigned to an observation group (OG) or a control group (CG) according to the treatment protocol, with 37 cases in each group.

Measurement of Radon Concentration Using SSNTD in Bartella Region

Al-Mustansiriyah Journal of Science, 2019
The alpha-radioactive inert gas Radon exhalation is associated with presence of Radium and its ultimate precursor uranium in the earth crust. Uranium decay deposits radon in soil, which is harmful on human and environment.

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 ...

Low‐Carbon Concrete Systems: A Comparative Review of Binder Technologies and Alternative Materials

Journal of Engineering, Volume 2026, Issue 1, 2026.
About 8% of the world′s carbon dioxide emissions come from the production of concrete, mostly from the clinker used to make regular Portland cement. By comparing supplementary cementitious materials (SCMs), alkali‐activated materials (AAMs), alternative aggregates, and waste‐derived elements using a shared carbon‐performance paradigm, this review ...
