Question- DTPA (Diethylenetriamine pentaacetate) is a medicine that can bind to a variety of radioactive chemicals. Which radioactive chemicals can be bound by DTPA?
Answer: DTPA comes in two forms: calcium (Ca-DTPA) and zinc (Zn-DTPA). Both forms work by tightly binding to radioactive plutonium, americium, and curium. These radioactive materials (bound to DTPA) are then passed from the body in the urine. (https://emergency.cdc.gov/radiation/dtpa.asp; accessed January 2018)
