Lognormal distribution of natural radionuclides in freshwater sediments and coal-ash repositories

, 1996
The distribution of natural radionuclides, K-40, Ra-226 and Th-232, in freshwater sediments and in coal-fired power-plant ash repositories has been tested for lognormality.

Thermal‐induced fracture evolution and acoustic signature of Beishan granite: Insights into tensile strength of barrier system for high‐level radioactive waste disposal

Deep Underground Science and Engineering, EarlyView.
The tensile strength of granite, a proposed host for nuclear waste, degrades severely above 400°C. We link this to specific microcracking patterns captured by acoustic emission, establishing a scientific basis for assessing repository safety under thermal load.

Marine Macroalgae as a Safe Healthy Food While Meeting Food Security Challenges Arising From Climate Changes

Food Safety and Health, EarlyView.
Planned harvesting and processing of marine macroalgae could meet future global food needs and mitigate fuel‐originated carbon dioxide responsible for climate change. Microalgal foods are nutritious and safe. The utilization of macroalgae would avoid environmental problems arising from the release of overgrowing macroalgae caused by heatwaves, which ...

Beach sediment dynamics from natural radionuclides point of view [PDF]

, 2022
This work assesses the use of natural radionuclides as tracers of marine sediment dynamic in a heterogeneous beach in Spain. Multivariant statistics was used to evaluate the spatial variability of the activity concentration of natural radionuclides.

Human biomarker navigator

iMeta, EarlyView.
The Human Biomarker Navigator integrates the disease continuum, biomarker dynamics, cross‐organ biomarker networks, biomarker classification, and technology‐driven paradigms. It maps how biomarkers link multi‐system physiology and pathology across the nervous, respiratory, endocrine, circulatory, immune, digestive, urinary, reproductive, and ...

Using a portable gamma-ray spectrometer to estimate the external exposure for a subway passenger

Радиационная гигиена
The subway (metro) is a popular form of public transportation system in many large cities. While in the subway territory (one of the locations in the city), a passenger is inevitably exposed to external irradiation from natural (terrigenous) sources of ...

Application of the Deconvolution Method to Alpha-Ray Energy Spectrum to Improve the Performance of a Radiation Airborne Particulate Monitor [PDF]

Journal of Radiation Protection and Research
Background At nuclear facilities and decommissioning sites, monitoring radioactivity concentrations in airborne particulates is crucial to prevent worker exposure. To avoid internal exposure, alpha-decay radionuclides must be detected.

Natural radionuclides in mineral fertilizers and farmland [PDF]

Veterinarski Glasnik, 2013
Contemporary agriculture production is based on use of mineral fertilizers, which however can have high activity of natural radionuclides and so cause the appearance of technologically elevated radioactivity.
