A Quench Index for 90Y and Its New Applications in 90Sr Analysis

He huaxue yu fangshe huaxue
Based on the customized quench index qx for 90Y and the modified 2-window approach, a simple method has been developed to analyze 90Sr using a liquid scintillation spectrometer, sometimes supplemented by γ spectrometer.

90Sr and 137Cs inventories in the depots and biogenic fluxes of the typical forest stands in the Chernobyl exclusion zone

, 2020
The paper reports results of the study of depots and biogenic fluxes of 90Sr and 137Cs in the typical coniferous (Scots pine) and deciduous (Silver birch) forest ecosystems of the Chernobyl Exclusion Zone during 2016 - 2018.

Energy-reduced beta radiation fields from 90Sr/90Y for the BSS 2

Journal of Instrumentation, 2020
For decades, the irradiation facility for beta radiation, the Beta Secondary Standard BSS 2 developed at PTB, has been in worldwide use to irradiate dosemeters, detectors and other devices with calibrated beta sources.

Coastal evolution, environmental change and carbon storage in the Thung Prong Thong Mangrove, eastern Gulf of Thailand

Boreas, EarlyView.
Palaeoenvironmental records along the eastern coast of Thailand remain sparse, with only a few studies attempting to reconstruct past climatic and environmental conditions. However, additional palaeoenvironmental, palaeoclimatic and sea‐level records are needed to improve our understanding of coastal evolution and local environmental changes.

Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

Boreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

Activity of 90Sr in Fallout Particles Collected in the Difficult-to-Return Zone around the Fukushima Daiichi Nuclear Power Plant.

Environmental Science and Technology, 2019
The Fukushima Daiichi Nuclear Power Plant (FDNPP) accident released abundant radioactive particles into the surrounding environment. Herein, we analyzed the activity of 90Sr in these particles to estimate the contribution of this radionuclide to the ...

Fluvial deposits of the Ahr river (western Germany) reveal recurring high‐magnitude flood events over the last 1,500 years

Earth Surface Processes and Landforms, Volume 51, Issue 1, January 2026.
Floods are one of the most critical environmental threats in Central Europe. We show the importance of geomorphological records from Ahr flood deposits for reconstructing past high‐magnitude flood events. Our chemolithostratigraphical analysis shows that centennial to millennial scale high‐energy flooding is not the exception but the rule in the Ahr ...

Estimation of radiation doses on lymphocytes and their progenitors after ingestion of strontium-89,90

Радиационная гигиена, 2022
In radiobiology circulating T-lymphocytes are used as “natural biodosimeters” since the frequency of chromosomal aberrations that occur in them after radiation exposure is proportional to the accumulated dose. In addition, stable chromosomal aberrations (

Novel method for determining of 137Cs in seawater using liquid scintillation counter

Limnology and Oceanography: Methods, Volume 24, Issue 1, January 2026.
Abstract Robust and efficient monitoring of radiocesium in the marine environment has become increasingly important, especially following the Fukushima Daiichi Nuclear Power Plant accident. A liquid scintillation counter (LSC) has been used for 137Cs analysis—which was identified as one of the hazardous radionuclides; however, a major limitation of ...

Radiological investigation of meat of game and dose estimation for hunters and members of their families

Journal of Environmental Engineering and Landscape Management, 2007
The paper describes dose estimation for hunters and members of their families due to radionuclides 90Sr and 137Cs in meat of game hunted in Lithuania during two hunting seasons: 2003–2004 and 2004–2005.
