radioactive cesium underway

Cesium, Radioactive Major Uses. Cesium metal's most recognized use is in the atomic clock that serves to define the second. Cesium has been considered as a fuel in ion-propulsion engines for deep space travel and as a heat-transfer medium for some applications. Cesium-137 has replaced cobalt-60 in the treatment of cancer and has been used in ...

Radionuclide Basics: Cesium-137. Cesium (chemical symbol Cs) is a soft, flexible, silvery-white metal that becomes liquid near room temperature, but easily bonds with chlorides to create a crystalline powder. The most common radioactive form of cesium is Cs-137. Cesium-137 is produced by nuclear. fission The splitting of an atomic nucleus into ...

Caesium 137 A legacy of atmospheric nuclear bomb tests and accidents. Caesium 137 is a radioactive element with a relatively long half-life of 30.15 years. This particular isotope of caesium is both a beta and gamma emitter. It is produced in some abundance by fission reactions. A lot of attention is focused on caesium 137 : it is the main ...

Caesium-137 (137 55 Cs), or radiocaesium, is a radioactive isotope of caesium that is formed as one of the more common fission products by the nuclear fission of uranium-235 and other fissionable isotopes in nuclear reactors and nuclear weapons.Trace quantities also originate from natural fission of uranium-238.It is among the most problematic of the short-to-medium-lifetime fission products.

After radioactive cesium is ingested, it is distributed fairly uniformly throughout the body's soft tissues. Slightly higher concentrations are found in muscle; slightly lower concentrations are found in bone and fat. Cesium-137 remains in the body for a relatively short time. It is eliminated more rapidly by infants and

The radioactive isotopes have a wide range of half-lives ranging from about 0.57 seconds (cesium-114) to about 3X10+6 years (cesium-135). The radioactive isotopes cesium-137 and cesium-134 are significant fission products because of their high fission yield, their long half-lives, and their biochemical similarity to potassium.

Cleanup underway after small radioactive chemical spill at TU's North Campus last year ... researchers were using the cesium for a joint industry project managed by the university's research office.

As part of this effort the Department of Nuclear Engineering and Radiation Health Physics at Oregon State University (OSU) was requested to construct a system capable of analyzing the concentration of radioactive cesium while underway in the Japanese seawaters.

The actinide-laden sludge solids and the cesium-laden strip effluent radioactive waste streams, removed from the salt waste by SWPF, have been sent to the DWPF. At that facility, the waste will be immobilized in glass and stored in stainless steel canisters onsite until …

The first step removes strontium and actinides (uranium, plutonium, etc.) from the waste. The second step, known as Caustic Side Solvent Extraction (CSSX), is designed for the removal of radioactive cesium. After the separation process is completed, the concentrated high-activity waste is sent to the nearby Defense Waste Processing Facility (DWPF).

Radiation Health Physics at Oregon State University (OSU) was requested to construct a system capable of analyzing the concentration of radioactive cesium while underway in the Japanese seawaters. In response to this request, OSU developed a flow-through monitoring tank to house a NaI(Tl) scintillation detector.

Investigation is underway to identify companies or individuals who used Cesium-137 in the country and dumped the toxic waste at the housing complex, he said. Nine residents of the neighborhood will undergo "whole body" examination to check the level of radioactive exposure at a Batan facility on Monday.
