Consider a van parked in a lot outside a professional football stadium in Atlanta, GA on a Sunday afternoon. One ounce of radioactive isotope Cesium 137 was mixed in with the explosive that has been detonated and has caused considerable blast damage. The dust cloud carries toward the nearby downtown area on a light wind speed of 10 mph. (Hint: Aristatek.com website for helpful in answering this question).
a. How could the bomb have been detonated?
b. A professional emergency responder should be concerned about the following routes of radiation exposure for a person on scene and a person downtown?
c. What actions should an exposed person take during the immediate aftermath of the explosion?
d. Lastly, if radioactive material is involved in a disaster incident such as this and there is a fire ongoing in the area where the container is located (possibly the container itself), name five actions that should be taken to handle the situation.
