radioactive cesium using acids was studied in Japan as well8). However, because the chemical processing will change the nature of the soil, its reuse after decontamination would be difficult. The use of this method in outdoor sites is problematic, and it may generate secondary wastes in the process of treating the soils with acid.

processes for the separation of cesium and strontium. The first Cs/Sr separation process utilizes chlorinated cobalt dicarbollide (CCD) and polyethylene glycol (PEG) in a phenyltrifluoromethyl sulfone diluent (3). The CCD/PEG process is most efficient when the feed is < .
is highly selective for removing cesium. The current process focuses on dissolving salt in Savannah River Site (SRS) Tank 10H, followed by processing in the TCCR skid loed near the tank. Four TCCR columns were constructed, loaded with CST, and installed in a .
· A novel cesiumtransporting bacterial pump developed by researchers at the NITech could be beneficial in radioactivity decontamination efforts. These findings were recently reported in .

Abstract The Nuclear Threat Initiative (NTI) has been working with various entities throughout the State
processes involved—either in the ground or in removing radioactive cesium from the tanks—there is a now a systematic way to proceed. Box THE WIDE IMPACT OF BES RESEARCH The key scientific idea underlying the nuclear waste cleanup process is what is known as molecular recognition: how to design a "host" molecule to recognize and bind to

Cesium137 (Cs137): has a halflife of years and decays by beta and gamma radiation. Cs137 is produced by nuclear fission for use in medical devices and gauges and is one of the byproducts of nuclear fission processes in nuclear reactors and nuclear weapons testing.
Fortunately, there are effective methods to remove radiation from water so that it is safe for drinking. The most effective methods for purifiion of radioactive water include active carbon, reverse osmosis, and ionexchange. Boiling your water is not an option. It .
Keywords: Environmental science, industrial processes, ion exchange modeling Abstract Nonelutable crystalline silicotitanate (CST) ionexchanger materials have been studied for removing cesium from a variety of radioactive wastes at several DOE sites over the last decade. For the current pretreatment
· Guanidine causes the cesium ions to pop out of the cage molecules, and boric acid strips them out of the solvent. STEP 3: Dispose and reuse. 1. Send the boric acid and cesium off for vitrifiion. The cesium is now in the boric acid and ready to be turned into a glass through a process called vitrifiion. 2. Send the treated solvent back for ...
· Caption: Diagram illustrates the process, in which contaminated water enters from the left, and is subjected to an ionic shockwave (depicted by dashed purple lines) that concentrates radionuclides of cesium and cobalt on one side (darker area at top) from purified water (lightcolored lower area). The clean water can be recirculated to the reactor, while the concentrated contaminants can be ...

A second possible method for removing cesium from Hanford wastes is an extraction process using magnetic microparticles. These particles are composed of magnetite (Fe. 3. O. 4), crystalline silicotitanate (CST), and polyacrolein, and are known by the trade name MagAcryl. TMCST. During the process cesium binds to the CST in the
· Cesium Therapy was developed by Dr. A. K. Brewer, chief of the National Bureau of Standards and Mass Spectrometer and Isotope Section. His primary interest had to do with cellular membrane behavior. He devised a study to examine the effects of cesium on cancer and treated 30 cancer patients. All of them survived [2][3].
