SCIENCE - Responding to the radiation threat

Scientists at the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) are developing a much more effective alternative that decontaminates a large number of the actinides likely to be part of the radiation exposure from a nuclear plant or weapon, including plutonium, americium, curium, uranium and neptunium. Furthermore, the Berkeley Lab treatment can be administered orally in the form of a pill, a necessity for prompt treatment in the event of mass contamination. Depending on the level of radiation exposure and how soon treatment can start, one of these pills would result in the excretion of approximately 90-percent of the actinide contaminants within 24 hours. Taking one pill daily for two weeks should be enough to remove virtually all of the actinide contaminants.
