1. Cobalt 60 is commonly used as a source in industrial radiography (nondestructive testing of steel products by imaging with gamma radiation). A typical Co source is 100 Curies. Given a half-life of 5.27 years: (a) Calculate the mass of Co needed for a 100 Ci source (Atomic mass = 59.9338 g/mole). (b) If the source is abandoned in a warehouse for 22 years, how many half-lives have elapsed? (c) How much activity remains?

Use the following information to answer the next question Food irradiation is sometimes used as a means of preserving perishable foods. A 320 g mass of cobalt-60 is used as a source of gamma radiation in an irradiation device. The half-life of cobalt-60 is 5.3 years. As the radiation released by the cobalt-60 declines, the device becomes less efficient. The cobalt-60 also undergoes beta negative decay. 3. Complete the following: Determine the amount of cobalt-60 remaining in the device after...
