Radioisotopes are used an variety to manufacturing and testing techniques Wear measurements can be made using the following method An automobile engine is produced using piston ring with a total mass of 108g that includes 8 4 x 105 Bq of Fe whose half life is 45 days The engine is test run for 45 days after which the oil is drained and its activity is measured If the activity of the engine oil is 84 decays s How much mass was lost in 10 gm hr from the piston rings per hour of operation
