Question: Neutron activation analysis is used to study a small sample of automotive enamel found at the scene of a hit-and-run collision. The sample was exposed

Neutron activation analysis is used to study a small sample of automotive enamel found at the scene of a hit-and-run collision. The sample was exposed to a thermal neutron flux of 3.5 x 10¹² neutrons/cm² . s for 2.0 minutes. Placed immediately in a gamma-ray detector, it was found to have an activity of 35 Bq due to ⁶⁰Co and 115 Bq due to ⁵¹Ti. Compute the total amount of each metal in the original sample. (The cross section for ⁵⁹Co is 19 b; that for ⁵⁰Ti is 0.15 b.)
