Calcium Phosphate is the calcium salt of phosphoric acid with widely used appliions. This agent can be used as a countermeasure for exposure to strontium and radium radionuclides. Upon oral uptake, calcium phosphate competes for and blocks the absorption of radium (Ra-226) and strontium in the gastrointestinal (GI) tract.
