FRIDAY, Aug. 13, 2004 (HealthDayNews) -- The U.S. Food and Drug Administration has approved two new drugs designed to counter the radioactive effects of a so-called "dirty bomb."
The agency said the drugs, penetrate calcium trisodium (Ca-DTPA) and penetrate zinc trisodium (Zn-DTPA), are safe and effective for treating contamination from plutonium, americium, or curium -- three elements that could be used to produce a dirty bomb.
Such a device would use conventional explosives to spread radioactive material across a wide area. While it wouldn't cause the death and destruction of a true nuclear device, it's easier to build and could still make a large area virtually uninhabitable, experts say.
The newly approved medications have been used for several decades as "investigational drugs" to treat people in radioactive emergencies, the agency said in a statement.
By speeding the process of removing radioactive elements from the body, the drugs can prevent certain cancers that could occur years after exposure, the FDA said.
