Excavation of terrestrial surface of the Earth could enhance the chance of exposure to radon while gases in the underground get access to escape. This study was aimed to assess the level of radon concentration from soil samples of quarrying sites at Hakim Gara in Ethiopia using CR-39 detectors in sealed container technique. The results of the measured radon concentration level were ranging from 164.

Mangrove forests are crucial coastal "blue carbon" ecosystems, known for their significant carbon sequestration capabilities to "carbon neutrality" and mitigating global climate change. We used Pb radioisotope dating to analyze sedimentation rates in the sediments of the Oujiang River Estuary mangrove forest, to calculate organic carbon burial rate, and to assess the characteristics and sources of organic carbon burial. The results showed that the average total organic carbon content in the sediments was 1.

Radiation is a pervasive natural phenomenon that has been present on earth since its inception. However, exposure to high background radiation levels can pose significant health risks to individuals living in affected areas. In recent years, several studies have been conducted in high background radiation areas (HBRAs), including high radon concentration areas, to understand the radiological aspects and the lessons learned of radiation exposure.

Estuaries significantly affect the transport of dissolved organic matter (DOM) from land to ocean. While the transport and composition of estuarine DOM have been extensively studied, the direct link between DOM chemistry and its age remains unclear, limiting a comprehensive understanding of the dynamics and fate of estuarine DOM under severe conditions (e.g.
