I. For example in radiography, the formula, rt = exp gives the total radiation exposure (exp) in mR as the product of the exposure rate, r, in mR/hr and the time of exposure, 1, in hours. 1. A technologist stands next to a 9Mo generator yielding an exposure rate of 38 mR/hr for 7 minutes. What is the technologist's total radiation exposure? Show your calculations in the space provided and round your answers to two decimal places. Circle your final answer and be sure to include the proper units. 2. Let's say we know the exposure someone came in contact with (exp) and the exposure rate (r) of the source. We are interested in finding how long the technologist was standing next to the source. a. One option would be to solve the original formula (highlighted) for the quantity we seek, in this case t. Solve the formula rt = exp for t. b. Suppose a technologist's total radiation exposure was 1.9 mR received from a 23 mR/hr source. Use the transformed formula you found in part a. to find the technologist's exposure time to the nearest minute.

For each of the following problems, substitute the given values in the formula and solve for the unknown. Check each answer. Round the answers to 2 decimal places. The length of cut, L, in inches, of a workpiece in a lathe is equal to the product of the cutting time, in minutes, T; the tool feed, F, in inches per revolution; and N, the number of revolutions per minute of the workpiece: L=TFN. Determine N when L=18 inches, T=2.5 minutes, and F=0.050 inch per revolution.
