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 ...

Evidence against correlations between nuclear decay rates and Earth-Sun distance [PDF]

, 2008
We have reexamined our previously published data to search for evidence of correlations between the rates for the alpha, beta-minus, beta-plus, and electron-capture decays of 22Na, 44Ti, 108Agm, 121Snm, 133Ba, and 241Am and the Earth-Sun distance.

Estimation of Radioactivity and Associated Radiological Hazards of Cement Used in Sri Lanka [PDF]

OUSL Journal, 2018
Cement used in construction work can cause internal and external radiation exposure due to the presence of natural radionuclides 226Ra, 232Th and 40K. The radiation exposure risk can be estimated by finding the indoor absorbed dose rate and the annual ...

Retention of 226Ra by montmorillonite

, 2022
Although 226Ra is a critical radionuclide in the safety analysis for deep geological disposal of spent nuclear fuel, adsorption data for 226Ra onto clay minerals are sparse in the open literature. So far, the adsorption and diffusion of 226Ra in clay minerals is assumed similar to that for Sr and Ba, based on chemical analogy. In this study, we present

Review of the anatomical basis for predicting plutonium alpha particle radiation induced osteogenic cancers

The Anatomical Record, Volume 308, Issue 12, Page 3197-3229, December 2025.
Abstract Plutonium was discovered and first synthesized in the early 1940's. Several isotopes of plutonium are used in nuclear technologies, 238Pu for heat generation and 239Pu for energy production and weapons. Both isotopes emit alpha particles, which pose a significant radiation hazard when incorporated into the body.

Overlooked seasonal groundwater nutrient fluxes rival anthropogenic point sources across a variable land‐use tidal river

Limnology and Oceanography, Volume 70, Issue 12, Page 3815-3831, December 2025.
Abstract Understanding groundwater–surface water connectivity in tidal freshwater zones is essential for managing ecosystems within the riverine–estuarine continuum. Groundwater discharge is a key source of dissolved nutrient loads that can lead to eutrophication, deoxygenation, and other ecosystem imbalances in coastal environments.
