These essays must be at least 200 words in length. Each essay must include at a minimum an introduction, a body, and a conclusion. Each essay requires at least 2 references: The textbook (Course book: Meyer, E. (2010). Chemistry of hazardous materials. Upper Saddle River, N.J:  Pearson. http://sdrv.ms/18Ghqq6  current chapter is Chapter 16) and one outside source must be used as source material for the response. All sources used, including the textbook, must be referenced; paraphrased and quoted material must have accompanying citations in APA Format.  MEYER, E. (2010). Chemistry of hazardous materials. (5 ed., pp. xxx-xxx). UPPER SADDLE RIVER, NJ:   PEARSONQuestion 1
 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.
Question 2
The best means of personal protection from radiation for
emergency responders is the implementation of three basic principles: time,
distance and shielding. Please show your work when answering the following
questions: 

a. Using the inverse square law of radiation, what Geiger counter reading would
you get for a radioactive material when you are 3 feet from the source (assume
an initial reading of 6300 R at a distance of 1 foot from the source)?
b. Dr. Brown has a radioisotope source containing 1.2 x 106 (also written as
1.2E+06) atoms of Plutonium-238 in 1985, how many atoms will remain in 352
years?
c. How many protons and neutrons are present in the plutonium-238 nucleus?
