Barium is a white, ‘radio-opaque’ powder that is visible with x-rays. It is used to demonstrate the structure and the function of the organs that make up the digestive tract, such as the oesophagus, the stomach, duodenum, small bowel and large bowel.

137 55 Cs --> 137m 56 Ba + e-+ ν e. As the Cs-137 nuclei decay to the Ba-137m nuclei, the Ba-137m atoms remain adsorbed on the surface of the resin. But because Barium has a different chemistry than Cesium, it is more loosely bound to the resin and can be de-adsorbed with a weakly acidic salt solution containing HCI and NaCI.

Barium carbonate is used in the production of optical glass, ceramics, glazed pottery, and specialty glassware. The sulfate is also an ingredient in oildrilling "muds" or slurries that lubricate the drill bit.
