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 an RBE of 1.1. What dose equivalent did she receive?

Jack was exposed to fast neutrons; he received a radiation dose of 120 rem on part of his hand, affecting 30.0 grams of tissue. The relative biological effectiveness (RBE) of these neutrons is 10.0. How much radiation did Jack receive? Express your answer in rads to three significant figures. What was the total energy of the radiation Jack received?Suppose Jill received the same rad dosage, but from beta rays with an RBE of 1.10 instead of from neutrons. What is...
