The name Barium comes from the greek word "barry", meaning heavy.
Where Can You Find Barium?
Uses of Barium
Barium Sulfate is used commonly in Radiology for CT scans and Barium studies. The mix of Barium Sulfate (Chemical Formula of BaSO4) appears white on X-Ray film.
When thee soulution is swallowed, the Barium coats the upper GI tract to help find and diagnose issues in the throat, stomach, or intestines.
This formula of Barium is safe to consume.
