Unformatted text preview: (343 hours after detonation), there are 3 seven-fold increases in time after detonation: (1 hour) (7)(7)(7) = 343 hours O Step 2: During three seven-fold increases in time, the magnitude of decrease in exposure rates is 1,000-fold. One thousand was calculated by multiplying 10 by itself three times: (10)(10)(10) = 1,000 O Step 3: The predicted exposure rate is 1 R/hr, which is 1,000 times less than the initial measurement of 1,000 R/hr. The solution for this step was performed as follows: Predicted exposure rate = Initial measurement Magnitude of decrease = 1 R/hr For this example, the solution for this step looks as follows: Predicted exposure rate = 1,000 R/hr 1,000 = 1 R/hr...
