Decontamination
Removing radioactive or chemical dust from the body: take off the outer layer of clothing, bag it, and wash with soap and water. See chs. 15 and 16.

A lack of water in the body. Thirst comes late: in heat and with exertion, drink even if you are not thirsty. With vomiting or diarrhea, use oral rehydration solution. See chs. 3 and 7.
Dirty bomb
A conventional explosive mixed with radioactive material. It aims to contaminate and cause fear; its effect is local and much smaller than that of a nuclear explosion. See ch. 15.

Do Not Use
A more serious water notice: any contact is dangerous. Use bottled water for everything, including personal hygiene. See ch. 16.
Drop, Cover, and Hold On
