Barium
An element of the alkaline earth group of metals. It has an atomic symbol Ba, atomic number 56, and atomic weight 138. All of its acid-soluble salts are poisonous.
Barium Compounds
Inorganic compounds that contain barium as an integral part of the molecule.
Year introduced: 1994
Barium Sulfate
A compound used as an x-ray contrast medium that occurs in nature as the mineral barite. It is also used in various manufacturing applications and mixed into heavy concrete to serve as a radiation shield.
Barium Radioisotopes
Unstable isotopes of barium that decay or disintegrate emitting radiation. Ba atoms with atomic weights 126-129, 131, 133, and 139-143 are radioactive barium isotopes.
Year introduced: 1988
Barium Enema
X-RAY examination of LOWER GASTROINTESTINAL TRACT. Imaging is done while a BARIUM COMPOUND (e.g., BARIUM SULFATE) fills the large intestine via the rectum as a CONTRAST MATERIAL.
