A tumor on a person's leg has a mass of 3.0 g. What is the minimum activity a radiation source can have if it is to furnish a dose of 10 Gy to the tumor in 14 min? Assume each disintegration within the source, on the average, provides an energy 0.70 MeV to the tumor.
The source activity must be at least `3.2*10^8" Bq"`.
