A beam of nuclei is used for cancer therapy. Each nucleus has an energy of 125 MeV, and the relative biological effectiveness (RBE) of this type of radiation is 16. The beam is directed onto a 0.180-kg tumor, which receives a biologically equivalent dose of 253 rem. How many nuclei are in the beam?

Jack underwent radiation therapy using a beam of neutrons to treat a skin cancer on his hand. He received a dose equivalent of 18 mSvmSv that was absorbed in 30 gg of tissue. The relative biological effectiveness (RBE) of these neutrons is 9.0. What absorbed dose of radiation did Jack receive? What was the total energy of the absorbed radiation? Suppose Jill, also being treated for skin cancer, received the same absorbed dose, but from an electron beam (beta particles) with...
Jack underwent radiation therapy using a beam of neutrons to treat a skin cancer on his hand. He received a dose equivalent of 2.0 Sv that was absorbed in 23 gof tissue. The relative biological effectiveness (RBE) of these neutrons is 10. A. What absorbed dose of radiation did Jack receive? B. What was the total energy of the absorbed radiation? C.
