Diethylenetriamine Pentaacetic Acid (DTPA)

The Oklahoma State Department of Health, through a program with the Centers for Disease Control and Prevention, maintains a forward deployment of injectable Diethylenetriamine Pentaacetic Acid (DTPA).  DTPA is effective as a countermeasure against certain types of radiation poisoning if used within 8 to 12 hours after a radiological (dirty bomb) attack or accidental radiological release.

DTPA is a chelating agent which binds and holds onto radioactive materials in the body.  Once bound to a radioactive material, the agent is then excreted from the body naturally.  DTPA is effective against plutonium, americium and curium and is administered through injection.  It comes in 5 ml (200mm mg/ml) clear glass ampoules.  

The metro areas of Oklahoma City and Tulsa each have a quantity of DTPA to treat several hundred patients.  The material is a stable chemical when kept at normal room temperature and humidity.  Existing supplies are stored in medical facilities and are easily transportable to the site of an incident whenever needed.
