"In what has to be one of the greatest accomplishments in the history of military medicine, the U. S. military has developed a radiation protection drug known as Ex-Rad that can give protection through DNA repair against otherwise lethal dosages of radiation. Ex-Rad, which is administered as an injection or orally, can be given either before or after exposure. While Ex-Rad officials are continuing to work with the FDA, it has successfully cleared two clinical studies showing it is safe."
