Jack underwent radiation therapy using a beam of neutrons to treat a skin cancer on his hand. He received a dose equivalent of 1.6 Sv that was absorbed in 22 g of tissue. The relative biological effectiveness (RBE) of these neutrons is 8.0.

Part a : What absorbed dose of radiation did Jack receive?Express your answer in grays to two significant figures.
Part b: What was the total energy of the absorbed radiation?Express your answer in joules to two significant figures.
Part c : Suppose Jill, also being treated for skin cancer, received the same absorbed dose, but from an electron beam (beta particles) with an RBE of 1.5. What dose equivalent did she receive?Express your answer in sieverts to two significant figures.

Answer:

Explanation:

a.) Dose equivalent is:

[tex]H= wD\\D=\frac{H}{w} =\frac{1.6}{8}=0.2Gy[/tex]

b.) [tex]D=\frac{E}{m}\\E=mD=(22\times 10^{-3}\times0.2)=4.4\times 10^{-3}J[/tex]

c.) The dose equivalent is:

[tex]H=wD=1.5 \times 0.2=0.3Sv[/tex]
