In preparation for a PET scan, a 75 kg patient is injected with fludeoxyglucose, a special type of glucose containing radioactive Fluorine-18 (18F). The injected solution contains 2.6 mCi of 18F, which has a half life of 109.8 minutes. Each radioactive particle has a mean energy of 249.8 keV, 90% of which is absorbed by the patient’s body. (1 mCi= 3.7*107 Bq.) a) Draw a graph showing the activity of the solution as a function of time. Label the half...

Technetium Dosage. Radioactive isotopes are often used for medical imaging. Technetium-99m (Tc-99m) is a particularly popular isotope since it has a short half-life and is easy to make. Also, Tc-99m can be chemically bonded to a number of different compounds and cell types for imaging different parts of the body. Tc-99m has a half-life of 6.02 hours. It decays into Tc-99 by emitting a gamma ray of energy 140 keV. For this problem, assume that Tc-99m is present in the...
