7. The DOT regulation at 49 C.F.R. §172.403 requires shippers to affix RADIOACTIVE YELLOW-III labels to a package having a transport index greater than 10 when the maximum radiation level at any point on the surface is greater than 2 mSv/h but less than or equal to 10 mSv/h. Are shippers required to affix RADIOACTIVE YELLOW-III labels to a package having a transport index greater than 10 if the maximum radiation level on its surface is measured to be 13 mrem/min? Yes, or No? 1) __________. What is 13 mrem/min in mSv/hr? 2) __________
8. Potassium-42 is a radioisotope that nutritionists use to determine whether the body is effectively using potassium at the cellular level. The half-life of potassium-42 is 12.4 hours. Assuming that a patient’s cells assimilate all the potassium chloride tagged with potassium-42, approximately what percentage of the dose remains in 2.1 days? __________ .
9. The best means of personal protection from radiation for emergency responders is the implementation of three basic principles: time, distance, and shielding. Using the Inverse Square Law of radiation, what Geiger counter reading would you get for a radioactive material when you are four feet from the source (assume an initial reading of 6300 R at a distance of 1 foot from the source)? __________ R.
10. __________ is a method used to compare the relative effectiveness of different explosives to accomplish a specific task. The detonation of 2.0 kg of tetryl has the same explosive power as 2) __________ pounds of TNT.

- The DOT regulation at 49 C.F.R. §177.835(a) requires shippers and carriers to load and unload explosives from a motor vehicle only when the engine is not operating. What is the most likely reason DOT prohibits operation of the vehicle’s engine during these processes?
- During an inspection of an abandoned site, a fire marshal discovers the presence of several dynamite sticks within a locked shed attached to a warehouse. Although some sticks are packed within a wooden box, others are lying on shelves. On checking the city’s records, the fire marshal discovers that the building was abandoned 22 years earlier. What immediate actions should the marshal take to protect public health, safety, and the environment? Aside from the explosive nature, discuss the health effects associated with its component nitroglycerin.
14. Discuss the nuclear reactions within the reactor of a nuclear power plant? Contrast the Three Mile Island, Chernobyl, and Fukushima Da-Ichi incidents with respect to the cause of the incident and radiation levels measured after the incident. Your response must be at least 200 words in length.
