Barium is an heavy metal, and its water-soluble compounds are often highly toxic.Barium sulphate is an inorganic compoundhaving chemical formula BaSO4 which is anwhite crystalline solid and insoluble in wate.In suspension itis frequently used clinically as a radiocontrast agent for X-ray imaging and other diagnostic procedures andmost often used in X-rayimaging of the GI tractby the name 'barium meal'. It is administered orally, or by enema, as a suspension of fine particles in a thick milk like solution.Its low solubility protects the patient from absorbing harmful amounts of the metal. Barium sulfate is also readily removed from the body. Due to the relatively high atomic numberwhich is56for barium, its compounds absorb X-rays more strongly than compounds derived from lighter nuclei.
