Question

Jack was exposed to fast neutrons; he received a radiation dose of 160 rem on part of his hand, affecting 21.0 grams of tissue. The relative biological effectiveness (RBE) of these neutrons is 12.0.

Jack recieved 13.3 rad of radiation

PART B.

What was the total energy of the radiation Jack received?

Express your answer in joules to three significant figures.

PART C.

Suppose Jill received the same rad dosage, but from beta rays with an RBE of 1.40 instead of from neutrons. What is the value of the equivalent dose she received?

Express your answer in rems to three significant figures.

Explanation / Answer

PART B.

What was the total energy of the radiation Jack received?

Jack recieved 13.3 rad of radiation

1 rad = .01 J/Kg

13.3 JKg * 0.021 =0.279 J

PART C.

Suppose Jill received the same rad dosage, but from beta rays with an RBE of 1.40 instead of from neutrons. What is the value of the equivalent dose she received?

Deq=13.3(rad) * 1.4
Deq = 18.62 rem
