Variability of activity concentrations and radial distributions of 137Cs and 90Sr in trunk wood of Scots pine and Silver birch.

Journal of Environmental Radioactivity, 2023
This study analyzes the variability of 137Cs and 90Sr concentrations in wood and their radial distributions in the trunks of Scots pine and Silver birch trees in the small uniformly contaminated forest stands in the Chornobyl Exclusion Zone ...

Fresh Groundwater Discharge as a Major Source of 90Sr into the Coastal Ocean.

Environmental Science and Technology, 2023
The behavior and source of 90Sr in the coastal ocean remain uncertain. Here, we investigated the distributions of 90Sr in coastal fresh groundwater, river water, pore water, and seawater in three bays along the southeastern coast of China between 2019 ...

Rapid analysis of 90Sr in cattle bone and tooth samples by inductively coupled plasma mass spectrometry

Journal of Analytical Atomic Spectrometry, 2021
Rapid analysis of 90Sr in bone and tooth samples of cattle was conducted by inductively coupled plasma mass spectrometry (ICP-MS). The ICP-MS method can be a rapid and useful procedure for determination of 90Sr in small bone and tooth samples.

Environmental 90Sr measurements

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1997
90Sr (T12 = 28.5 years) is a long-lived radionuclide produced in nuclear fission. Fast radiochemical detection of 90Sr in environmental samples is not feasible using current analytical methods. Accelerator Mass Spectrometry (AMS) measurements of 90Sr were made with the Rehovot 14UD Pelletron accelerator at a terminal voltage of 11 or 12 MV using our ...

Measurement of 90Sr in bone ash

Applied Radiation and Isotopes, 1998
Bone is a critical organ for the accumulation of many radionuclides, including 90Sr. A bone ash has been prepared by NIST to become a standard reference material and the assaying of the 90Sr activity concentration is reported. A radiochemical procedure, based on extraction chromatography using a crown ether, has been developed to separate Sr from the ...

90Sr in lake sediments

Journal of Radioanalytical and Nuclear Chemistry, 1997
For a better understanding of the behaviour of90Sr in aquatic systems, this β-emitter has been determined in the different layers of a lake sediment core which has been previously dated using the well established210Pb dating method. For this, a radiochemical technique has been developed for the isolation of strontium from the sediment samples and for ...

Long-term mobility of fallout 90Sr in ploughed soil, and 90Sr uptake by wheat grain

Science of The Total Environment, 2007
In this study, we evaluated the mobility of 90Sr in ploughed upland soil, which affects the residual amount in the soil and plant uptake on the basis of long-term monitoring data. Paired samples of soil and wheat grain were taken annually from 1961 to 1995 from 8 agricultural fields in Japan, and the concentrations of exchangeable 90Sr in soil and ...
