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.
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.
nitric acid is usually purchased in concentrated form with a 70.3 hno3 concentration by mass and a density of 1.41 gml.
A sample of krypton gas at a pressure of 0.621 atm and a temperature of 20.7oC, occupies a volume of 17.2 liters. If the gas is compressed at constant temperature to a volume of 5.62 liters, the pressure of the gas sample will be

A patient is given 5.5 x10^-2 mg of technetium-99 m, a radioactive isotope with a half-life of about 6.0 hours.How long untilth radioactive isotope decays to 6.0 x10-3 mg? (assume no excretin of the nucelotibe from the body.) Answer is in T =hours.
The value of Ka for nitrous acid (HNO2) at 25C is 4.5*10^-4. What is the value of deltaG when [H+]= 5.9*10^-2 M, [NO2^-]= 6.1*10^-4 M, and [HNO2]= 0.19 M
A criticism of this prediction is that the melting of icebergs does not increase ocean levels any more than the melting of ice in a glass of water increases the level of liquid in the glass. Is this a valid criticism
