Barium sulfate | BaSO4PubChem

Barium sulfate is a heavy metal with a high atomic number (Z=56) and a K shell binding energy (K-edge of 37.4 keV) very close to that of most diagnostic x-ray beams. Due to these characteristics, barium is an ideal medium for the absorption of x-rays. Barium sulfate is essentially not absorbed from the GI tract nor metabolized in the body. Barium sulfate is used to fill the gastrointestinal tract lumen or to coat the
