A 2.0-kg tumor is being irradiated by a radioactive source. The tumor receives an absorbed dose of 12 Gy in a time of 750 s. Each disintegration of the radioactive source produces a particle that enters the tumor and delivers an energy of 0.35 MeV. What is the activity N//t of the radioactive source?© BrainMass Inc. brainmass.com March 4, 2021, 5:56 pm ad1c9bdddf
Absorbed Energy (Joules) = Absorbed Dose (Gy) * Mass (kg)
= 12 ...
Provides steps necessary to determine the activity N//t of the radioactive source.
