Final Examination F-9 36. Just as in an emergency resulting from a nuclear power accident, the three most important ways of reducing the radiation exposure from fallout from a nuclear weapon are: a. Time, shelter, and gender b. Dose rate, distance, and time c. Dose rate, distance, and shielding d. Time, distance, and shielding 37. Radioactive fallout makes the surface it comes into contact with radioactive. (True or False?) a. True b. False 38. Radiological survey instruments: a. Will not be very reliable after a nuclear detonation because of weak batteries and no sure way of checking the strength of those batteries b. Will give just an approximate answer which will need to be corrected using the "7: l0 Rule of

Will be very reliable following a nuclear detonation since they usually use AC line current 39. According to the "7:10 Rule of Thumb," if the exposure rate one hour after detonation of a nuclear weapon is 500 R/hr, the exposure rate approximately 14 days later (343 hours) will be approximately: a. 50 R/hr b. 5 R/hr c. 0.5 R/hr d. 0.05 R/hr 40. The 7:10 Rule of Thumb: a. Is 100 percent accurate b. Helps estimate future exposure levels c. Is more reliable than radiological survey instrument readings d. Is accurate to within +10 percent...
