Organic Carbon Burial Rates in Muddy Temperate Shelf Sea Sediments

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Muddy continental shelf sediments act as important sinks for atmospheric CO2 by accumulating organic matter, a small fraction of which is buried and stored as organic carbon (OC) over long timescales. Quantifying long‐term OC burial in shelf sediments is critical for understanding their role in climate regulation; however, this remains ...

Pan‐Arctic Peatlands Have Expanded During Recent Warming

Global Change Biology, Volume 32, Issue 2, February 2026.
Arctic peatland carbon is important because it represents a large carbon stock that may be vulnerable to climate change. This work explores the expansion and/or shrinkage of Arctic peatlands using observations in two north–south transects in Canada and in Europe.

Activity Levels of Polonium-210 in Tobacco and Cigarette in Iran [PDF]

مجله علوم و فنون هسته‌ای, 2011
Polonium-210 (210Po) is a natural contaminant of tobacco and its products. Due to its volatility and inherent adsorption properties, 210Po is one of the major potential sources of human exposure through smoking.

Astatine‐211—Towards In Vivo Stable Astatine‐211 Labeled Radiopharmaceuticals and Their (Pre)Clinical Applications

Medicinal Research Reviews, Volume 46, Issue 1, Page 203-237, January 2026.
ABSTRACT Targeted radioligand therapy has emerged as a promising treatment option for eradicating advanced cancer forms. α‐Emitters are considered particularly promising as they can obliterate (micro)‐metastases. The α‐emitter astatine‐211 (211At) has experienced increased interest due to its favorable decay properties.

Nuclear data uncertainty analysis for the Po-210 production in MYRRHA

EPJ Nuclear Sciences & Technologies, 2018
MYRRHA is a multi-purpose research reactor able to operate in sub-critical and critical modes and currently in the design phase at SCK•CEN. The choice of LBE was driven by its chemical stability, low melting temperature, high boiling point, low chemical ...

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.

An absorbed dose‐based source strength determination for diffusing alpha‐emitters radiation therapy (DaRT) brachytherapy seeds – Proof of concept

Medical Physics, Volume 52, Issue 12, December 2025.
Abstract Background Diffusing alpha‐emitter radiation therapy (DaRT) is currently being evaluated in several clinical trials as an interstitial temporary brachytherapy source. However, determining source strength solely based on gamma spectrometry measurements of 224Ra activity has limitations. This method does not account for changes in the desorption

The Radiological Impact of 210Pb and 210Po Released from the Iron- and Steel-Making Plant ILVA in Taranto (Italy) on the Environment and the Public

Journal of Chemistry, 2013
Lead-210 and 210Po are naturally occurring radionuclides. Due to volatile characteristic of lead and polonium, environmental pollution of 210Pb and 210Po released from the coal power plant, steel-making industry and refractory material industry has been ...

Flood‐Driven Turbidite Deposition in a Highstand‐Detached Submarine Canyon

Geophysical Research Letters, Volume 52, Issue 21, 16 November 2025.
Abstract Turbidites on active margins represent key archives of great earthquakes, yet turbidity currents triggered by non‐seismic events complicate paleoearthquake records and influence geochemical budgets. Sediment cores collected from highstand‐detached Astoria Canyon address whether non‐seismic turbidity currents are preserved in canyon ...
