Preparation conditions of composite ion-exchanger based on stannic molybdophosphate (SMP) and poly-acrylamide (PAA) have been described. Batch distribution coefficients for some ions were investigated at 25 °C. Sodium ion exchange capacity and breakthrough curves of cesium and strontium ions have also been determined.

Abstract The removal and separation of Co-60, Sr-90, and Cs-137 radioisotopes from nitrate aqueous solutions were studied by competitive transport across cellulose triacetate plasticized membranes using organophosphorous acids compounds (D2EHPA, Cyanex 272, Cyanex 301 and Cyanex 302). Competitive transport of trace radionuclides ions from 0.10 M NaNO

This study aimed to reveal local structures of strontium (Sr) and cesium (Cs) adsorbed on clay minerals (vermiculite and montmorillonite), which suggests stabilities of the adsorbed species of 90Sr and 137Cs in the environment. Adsorption experiments to determine solid-water distribution, XRD for interlayer distances of the clay minerals, and EXAFS for

An amorphous, partially-reduced tin dioxide, having properties of an inorganic exchanger, was tested for application to fission product separations. Due to the good sorption of both strontium and barium the application of the exchanger to radiostrontium isolation from fission product mixtures is subject to important restrictions. An application to 90Sr

Uptake of cesium and strontium radioisotopes onto pillared clays
Journal of Radioanalytical and Nuclear Chemistry, 1999Abstract Pillared clays were characterised by thermal analysis and small-angle X-ray scattering. They were then examined for their ability to take up137Cs and90Sr/90Y isotopes as a function of concentration and competing cations (Na+, K+, NH4 +, Ca2+, Mg2+) in the concentration range 10−1 to 10−4 M. The radioisotope uptakes were quantified byK d (ml/g)

Current Opinion in Oncology, 1994
New advances in systemic radionuclide therapy have increased the number of treatment options available for patients with painful osseous metastases. This form of therapy has three major appeals: 1) it addresses all sites of involvement; 2) selective absorption into bone limits irradiation of normal tissues; and 3) as a result, toxicity may be reduced ...

Passive Detection of Concealed Strontium-90 Radioisotope Thermoelectric Generators in Transport
Packaging, Transport, Storage & Security of Radioactive Material, 2004Abstract Many radioisotope thermoelectric generators (RTGs) used in civilian and military applications employ 90Sr, a high-energy beta emitter. The possibility of indirect or deliberate contamination of the environment with this isotope is not negligible.
