Work Step by Step
a. 5.0 Gy. A Gy is 1.0 J/kg.
$5.0Gy\frac{rad}{0.010Gy}=500rad$.
The RBE for x-rays is 1.0, so by equation 43.20, the equivalent dose in sieverts is $RBE \times 5.0Gy=5.0Sv$.
The RBE for x-rays is 1.0, so by equation 43.21, the equivalent dose in rem is $RBE \times 500rad=500rem$.
b. Total energy is $\frac{5.0J}{kg}(70.0kg)=350J$
c. The absorbed dose and total absorbed energy are the same, but RBE = 10 for protons, so the equivalent doses are 10 times larger.
The answers are: 5.0 Gy, 500 rad, 50 Sv, 5000 rem, 350 J.
