Potential of Soils Natural Sorbents for Environmental Decontamination From 137Cs
Land Degradation &Development, Volume 37, Issue 2, Page 779-789, 30 January 2026.ABSTRACT This study addresses the existing research gap concerning the lack of integrated data on the role of in situ soil components in the long‐term fixation of 137Cs under natural, protected, and non‐agricultural conditions. The contamination of ecosystems by radioactive isotopes, particularly 137Cs, represents a considerable environmental hazard ...

Technical note: Comparison of radiometric techniques for estimating recent organic carbon sequestration rates in inland wetland soils [PDF]
BiogeosciencesFor wetlands to serve as natural climate solutions, accurate estimates of organic carbon (OC) sequestration rates in wetland sediments are needed. Dating using cesium-137 (137Cs) and lead-210 (210Pb) radioisotopes is commonly used for measuring OC ...

Advanced Science, Volume 13, Issue 2, 9 January 2026.The advent of aptamers has highlighted their potential as alternatives to antibodies, overcoming limitations of structural instability and production cost. However, conventional approaches such as SELEX remain slow and labor‐intensive. This review examines recent advances in aptamer engineering, emphasizing in vitro and AI‐driven in silico strategies ...

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 ...
