Barium is a white liquid used to coat the organs of the digestive system during an X-ray. This can help to provide a clearer picture of a person's organs and bones to help reaching a diagnosis.

Barium is used as marker fluid for visualization of intestine in X-ray diagnostic test termed as barium enema. BARIUM-137 isotope is used for studies of high-temperature superconductors; Barium-137 isotope is available to order from BuyIsotope.com in Barium-137 carbonate (BaCO3) chemical form. Please contact us via request a Barium-137 isotope quote BuyIsotope.com to order Barium-137 isotope, to get Barium-137 price and to buy Barium-137 isotope. Cesium-137 undergoes high-energy beta decay, primarily to an excited nuclear isomer of Barium 137, which in turn undergoes gamma decay with a half-life of about 150 seconds. [4] The energies of both the beta decay of cesium-137 and the subsequent gamma decay of the excited barium 137 are 512 keV and 662 keV, respectively. [4] is it safe to use hand sanitizer?

Barium is the fifth element in group 2 and is a soft, silvery alkaline earth metal. Because of its high chemical reactivity, barium is never found in nature as a free element. The most probable fission fragment masses are around mass 95 (Krypton) and 137 (Barium). Barium – Properties

Ba – Barium Introduction Barium is a member of group 2 elements of the periodic table, along with Be, Mg, Ca and Sr, which are all highly electropositive metals. The element has an atomic number of 56, an atomic mass of 137, one oxidation state (+2), and seven naturally occurring isotopes (130Ba, 132Ba and 134Ba to 138Ba), of which 138Ba is of Cs-137 according to the scheme shown in Figure 2. As the Cs-137 atoms decay to the Ba-137m atoms, the Ba-137m atoms remain adsorbed on the surface of the resin, but because barium is in a different chemical form than the cesium was previously, it is more 5 Barium is a chemical element with the symbol Ba and atomic number 56.

This is a ‘barium meal’ or ‘barium enema’. Barium is a heavy element and scatters X-rays, so as it passes through the body the stomach and intestines can be distinguished on an X-ray. Another use of barium is to remove gases from vacuum tubes. It was very common to find barium in electronic industry especially television. Barium helps to remove gases from the tube that will turn into television display. Thus, it will not leak gas and causes any harmful incident. The longest-lived isomer is 133m Ba, which has a half-life of 38.9 hours, though the shorter-lived 137m Ba (half-life 2.55 minutes) arises as the decay product of the common fission product caesium-137.
