Larger Cs-137 sources are enclosed in lead containers (such as long tubes that are closed at each end) or small round metal containers. If the lead containers of Cs-137 are opened, the substance inside looks like a white powder and may glow. The Cs-137/Ba-137m isotope generator has been specifically designed for use in schools and universities to demonstrate the physical properties of radioactive decay. Based on the original Union Carbide design, the isotope generator offers exceptional performance while maintaining ease of use and safe operation. Pergamon Press. Printed in Northern Ireland The results of the calibration measurements are listed in Table 1 and a summary of the calibration The Decay Scheme of Caesium 137 factors given in Table 2. Cesium-137 and its decay product, barium-137m, are used for sterilization activities for food products, including wheat, spices, flour, and potatoes. Cesium-137 is also 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 The atomic number increases by one, because one more proton is formed. Because the atomic number changes, this is a new element, number 56, barium, or ""_56^137Ba In the form of an equation, this is written as ""_ 55^137Cs -> ""_ 56^137Ba + ""_"-1"^0beta This video shows a sample of Cs-137 being tested by a hand-held detector.

Caesium-137 (137 55 Cs), or radiocaesium, is a radioactive isotope of caesium which 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 Cesium Cs 137 is a radioactive isotope of cesium with an atomic mass of 139 and potential application in radiotherapy. Cesium Cs 137 is prevalent due to its spontaneous production, which occurs as a result of nuclear fission of other radioactive materials, such as uranium and plutonium.This radionuclide has a relatively long half-life, 30 years, and decays by emitting beta particles.
