Barium sulfate solubility is less than 0.01, not easily absorbed by the human body, and does not react with chlorohydrogen acid; barium nitrate and barium chloride are extremely soluble in water, very easy to be absorbed by the human body; barium carbonate meets the gastric acid will produce this reaction (BaCO3 + 2HCl = BaCl2 + CO2 ↑ + H2O), resulting in barium chloride, barium is a heavy metal, which is absorbed by the human body will cause heavy metal poisoning. So use barium sulfate.
