Question
Radioisotopes are used in a variety of manufacturing and testing techniques. Wear
measurements can be made using the following method. An automobile engine is
produced using piston rings with a total mass of 100 g, which includes 9.4 mCi of 5°FE
whose half-life is 45 days. The engine is test-run for 2000 hours, after which the oil is
drained and its activity is measured. If the activity of the engine oil is 5.49 x 103
decays/s.
(b) What would be the activity in the piston after 0.112 grams has been worn off the
piston?
