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 ...

The mutagenic effect of 90Sr in barley

Mutation Research, 1970
Abstract The mutation frequency in the pollen character waxy was investigated in barley plants cultivated on soil contaminated with 90 Sr. Doses in the range of human safety interest were mutagenic. The mutation frequency per dose unit was higher in the lowest dose region than at moderate doses.

The toxicity of 90Sr, 226Ra and 239Pu

Nature, 1976
Data now available on the risks of radiation-induced fatal cancer and hereditary disease and radionuclide metabolism suggest that limits on the rates of intake of 90Sr, 226Ra and 239Pu at work, presently recommended by the International Commission on Radiological Protection, might be in need of considerable revision one with another and with the limit ...

UPTAKE OF 137Cs AND 90Sr IN RICE PLANTS

Health Physics, 2003
In order to study the transfer of water-borne 137Cs and 90Sr into rice plants, pot experiments were done by growing rice plants on soils taken from rice beds near two nuclear power plants: Qinshan Nuclear Power Plant and Daya Bay Nuclear Power Plant in China.

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 ...

Inventory and vertical migration of 90Sr fallout and 137Cs/90Sr ratio in Spanish mainland soils

Journal of Environmental Radioactivity, 2011
In this paper the inventory of (90)Sr in 34 points distributed along the Spanish peninsular territory is presented. Obtained values range between 173 Bq/m(2) and 2047 Bq/m(2). From these data set and those (137)Cs data obtained in a previous work the (137)Cs/(90)Sr activity ratio has been established, laying this value between 0.9 and 3.6.

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 ...

Biokinetics of 90Sr after chronic ingestion in a juvenile and adult mouse model

Radiation and Environmental Biophysics, 2011
International audienceThe aim of our study was to define the biokinetics of 90Sr after chronic contamination by ingestion using a juvenile and adult murine model. Animals ingested 90Sr by drinking water containing 20 kBq l -1 of 90Sr.

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 ...

Biokinetics of 90Sr in Male Nonhuman Primates

Health Physics, 2016
The current study tests the hypothesis that the biokinetics of Sr can be represented by simplification of the ICRP publication 78 Sr model. Default and proposed models were evaluated by their ability to predict injected activity and more thoroughly define the activity residing in the skeleton of rhesus monkeys.
