Analysis of Radon‐222 in Surface and Groundwater Sources in Kajiado County, Kenya

The Scientific World Journal, Volume 2026, Issue 1, 2026.
This study entailed measurement of the concentration of 222Rn in surface and subsurface water sources from Kajiado Municipality in Kenya. Kajiado County receives minimal rainfall and is not well covered by the municipal treated water network. The residents of the area mainly rely on subsurface water sources for their domestic consumption.

Personal Dosimetry Enhancement for Underground Workplaces

Acta Polytechnica, 2005
Personal dosimetry for underground workers mainly concerns measurement of the concentration of radon (and its daughters) and the correct application of the data in dose calculation, using a biokinetic model for lung dosimetry. A conservative approach for

Techniques and Advances in Ultrafast Photography

Advanced Photonics Research, Volume 6, Issue 12, December 2025.
This review maps the fast‐growing field of ultrafast photography from early mechanical cameras to modern optical‐computational methods. It organizes techniques into four families (multishot passive/active; single‐shot passive/active), explains how they reach trillion‐frame‐per‐second speeds, compares capabilities and tradeoffs, and highlights ...

Advances in the Diagnosis, Treatment, and Management of Liver Nodules: A Comprehensive Review

Portal Hypertension &Cirrhosis, Volume 4, Issue 4, Page 232-251, December 2025.
Liver nodules commonly occur due to various causes, some of which are malignant or may undergo malignant transformation, leading to disease progression or delayed detection in clinical practice. The widespread use of imaging methods has increased the detection rate of liver nodules. Furthermore, precision medicine techniques and artificial intelligence

Insights Into the Comprehensive Carbon Cycle in a Mangrove Ecosystem: A Case Study for Understanding Carbon Burial, Outgassing, and Outwelling in a Subtropical Island

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 12, December 2025.
Abstract A significant quantity of soil organic carbon (SOC) is buried in mangrove ecosystems. However, recent research has revealed that substantial amounts of carbon are exported to the atmosphere as CO2 or to the ocean as dissolved inorganic carbon (DIC), dissolved organic carbon (DOC), and particulate organic carbon (POC).

Uranium, radium and thorium in soils with high-resolution gamma spectroscopy, MCNP-generated efficiencies, and VRF non-linear full-spectrum nuclide shape fitting

EPJ Web of Conferences, 2017
A new method for analysis of uranium and radium in soils by gamma spectroscopy has been developed using VRF (“Visual RobFit”) which, unlike traditional peak-search techniques, fits full-spectrum nuclide shapes with non-linear least-squares minimization ...
