Let us know look at some more information and facts about Cesium. Cesium has 11 main radioactive isotopes. Out of the above mentioned isotopes, the main ones of concern are cesium-134, cesium-135 and cesium 137. Cesium is present naturally in the soil and also as isotope 133.

Cesium-137 and its decay product, barium-137m, are used in food sterilization, including wheat, spices, flour, and potatoes. Cesium-137 is used in a wide variety of industrial instruments, such as level and thickness gauges and moisture density gauges. Cesium-137 is also commonly used in hospitals for diagnosis The suggestion to use caesium-137 (137Cs) as a tracer for soil erosion assessment originated in the 1960s when environmental scientists investigated land contamination by radionuclides released during nuclear weapons tests.

Background. Cesium-137 (137 Cs) is a radioisotope that has been used in both interstitial and intracavitary brachytherapy.Although Cs-137 decays via beta – decay, it is the daughter nuclide’s subsequent gamma emissions that are responsible for most dose when used as an enclosed source in cancer treatment. 2014-09-16 Cesium-137: A Deadly Hazard Colin Wessells March 20, 2012 Submitted as coursework for PH241, Stanford University, Winter 2012 Introduction.

Cesium-137 is useful in medical and industrial radiology because of its long half-life of 30.17 years. However, as a major component of nuclear fallout and a waste product left over from the production of plutonium and other enriched nuclear fuels, it presents an environmental hazard.

Cesium-137 (137 Cs) is a radioisotope that has been used in both interstitial and intracavitary brachytherapy. Although Cs-137 decays via beta – decay, it is the daughter nuclide’s subsequent gamma emissions that are responsible for most dose when used as an enclosed source in cancer treatment. Cesium (Cs) is a metal with atomic number 55, group 1, and period 6.

60 Co produces gamma rays with energies of 1.173 and 1.332 MeV and has a half-life of 5.27 years, whereas 137 Cs produces gamma rays with an energy of 0.662 MeV and has a longer half-life of 30.1 years. Cesium-137 has replaced cobalt-60 in the treatment of cancer and has been used in industrial radiography for the control of welds. Cesium-137 is also used commercially as a sealed source in liquid scintillation spectrometers. Naturally occurring cesium is the non-radioactive isotope, cesium-133. In addition, twenty radioactive isotopes ranging from cesium-123 to cesium-144 have been artificially prepared. Cesium-137 is useful in medical and industrial radiology because of its long half-life of 30.2 years. Cesium-137 remains radioactive for approximately 180 years.
