Fast concentration of dissolved forms of cesium radioisotopes from large seawater samples
Journal of Radioanalytical and Nuclear Chemistry, 2012The method developed for cesium concentra- tion from large freshwater samples was tested and adapted for analysis of cesium radionuclides in seawater. Concen- tration of dissolved forms of cesium in large seawater samples (about 100 L) was performed using composite absorbers AMP-PAN and KNiFC-PAN with ammonium molybdophosphate and potassium-nickel ...

Contaminated Marine Sediments As a Source of Cesium Radioisotopes for Benthic Fauna near Fukushima
Environmental Science & Technology, 2016Marine animals, seawater, and sediment near Fukushima, Japan have become contaminated with 134Cs and 137Cs released in March 2011 from the damaged Fukushima Dai-ichi nuclear power plant. Radiocesium concentrations in some benthic fauna declined more slowly than in pelagic fish in the same region. We tested the hypothesis that benthic fish remained more

Applied Radiation and Isotopes, 2019
Poly (acrylamido-sulfonic acid) polymers have been synthesized using the technique of radical chain polymerization utilizing acrylamide and ammonium persulphate. The polymerization was triggered and controlled using radiation from 1.1 μCi radium source. The polymer sheet was characterized using FTIR, DTA, TG, XRD and SEM.

Journal of Radioanalytical and Nuclear Chemistry, 2007
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
