Problem regarding the radioactive source

Assignment Help Physics
Reference no: EM131162270

A 0.69-kg tumor is being irradiated by a radioactive source. The tumor receives an absorbed dose of 13 Gy in a time of 960 s. Each disintegration of the radioactive source produces a particle that enters the tumor and delivers an energy of 0.44 MeV. What is the activityN/t(in Bq) of the radioactive source?
