Emergency decontamination has become a major response objective of first responders to terrorist incidents. Botulinum toxin, supportive care and antitoxin. The longer a contaminant is in contact with an object, the greater the probability and extent of permeation. Solidifying liquid or gel contaminants can enhance their physical removal. You can remove radioactive materials that are on the body of others or you can remove radioactive materials if they are on your body (self-decontamination).
