Jack was exposed to fast neutrons; he received a radiation dose of 300rem on part of his hand, affecting 22.0grams of tissue. The relative biological effectiveness (RBE) of these neutrons is 9.00.
a.How much radiation did Jack receive?
b.What was the total energy of the radiation Jack received?
c.Suppose Jill received the same rad dosage, but from beta rays with an RBE of 1.30 instead of from neutrons. What is the value of the equivalent dose she received?
