A nuclear detonation occurred at 1235 local time. Your unit is in the fallout area and the CDR wants to know what time they can exit the area and still minimize exposure to fallout. Currently your unit is on the top floor of a multistory building. When you evacuate you will use 5-ton trucks. You estimate it will take your unit 3 hours to evacuate the contamination area. What is your optimum time of exit?
