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...
