A 3.75-kg tumor is being irradiated by a radioactive source. The tumor receives an absorbed dose of 14.6 Gy in a time of 725 s. Each disintegration of the radioactive source produces a particle that enters the tumor and delivers an energy of 0.605MeV. What is the activity of the radioactive source?

    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...
