Solved: During the manufacture of a steel engine
Chapter 29, Problem 29.1(choose chapter or problem)
During the manufacture of a steel engine component, radioactive iron (59Fe) is included in the total mass of 0.20 kg. The component is placed in a test engine when the activity due to the isotope is 20.0 mCi. After a 1 000-h test period, oil is removed from the engine and is found to contain enough 59Fe to produce 800 disintegrations/ min per liter of oil. The total volume of oil in the engine is 6.5 L. Calculate the total mass worn from the engine component per hour of operation. (The halflife of 59Fe is 45.1 days.)
