Preparation and evaluation of composite ion-exchanger for the removal of cesium and strontium radioisotopes

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.

Fast concentration of dissolved forms of cesium radioisotopes from large seawater samples

Journal of Radioanalytical and Nuclear Chemistry, 2012
The 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 ...

Transport of the Radioisotopes Iodine-131, Cesium-134, and Cesium-137 from the Fallout Following the Accident at the Chernobyl Nuclear Reactor into Cheese and Other Cheesemaking Products

Journal of Dairy Science, 1987
The transport of radiation contamination from milk to products of the cheese making process has been studied. The concentration of radioactive iodine and cesium in samples of sheep milk and cheese (Gruyère) products was measured for 10 consecutive production d.

Treatment Technology of Hazardous Water Contaminated with Radioisotopes with Paper Sludge Ash-Based Geopolymer—Stabilization of Immobilization of Strontium and Cesium by Mixing Seawater [PDF]

Materials, 2018
Long-term immobilization ratios of strontium (Sr2+) and cesium (Cs+) in paper sludge ash-based geopolymer (PS-GP) were investigated in one year. PS-GP paste specimens were prepared in the conditions of 20 °C and 100% R.H., using two kinds of paper sludge ash (PS-ash). Two kinds of alkaline solution were used in the PS-GP as activator.

Sorption characteristics of an economical sorbent material used for removal radioisotopes of cesium and europium

Journal of Radioanalytical and Nuclear Chemistry, 2010
Application study for the evaluation of sorption characteristics of sawdust as an economical sorbent material used for decontamination of radioisotopes cesium and europium from aqueous solution has been carried out in the present work. In this respect, sawdust (untreated and treated by HNO3) has been prepared from the commercial processing of wood for ...

Removal of cesium radioisotopes from solutions using granulated zeolites

Journal of Radioanalytical and Nuclear Chemistry, 1991
The influence of type of zeolite and the flow rate of the solution through the column on the removal efficiency of radioactive Cs ions from solution has been investigated. The analysis of the change in concentration of Cs ions in the solutions and distributions of Cs ions in the column fillings (granulated zeolites), after passing the solutions through

Uptake of cesium and strontium radioisotopes onto pillared clays

Journal of Radioanalytical and Nuclear Chemistry, 1999
Abstract  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)

Excitation Functions for the Formation of some Radioisotopes of Cesium and Iodine in Proton and Deuteron Induced Nuclear Reactions on Natural Xenon

Radiochimica Acta, 1989
Excitation functions were measured using the 'stacked gas cell' technique for the fomation of {sup 127,129,132,134,136}Cs and {sup 124,126,130,131,133I} from natural xenon in proton induced reactions over the energy range of 9 to 43 MeV, and for {sup 127,129,132}Cs and {sup 124,126,130,131,133}I from in deuteron induced reactions over 22 to 53 MeV ...

Contaminated Marine Sediments As a Source of Cesium Radioisotopes for Benthic Fauna near Fukushima

Environmental Science & Technology, 2016
Marine 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
