1. A hospital patient receives an x-ray dose of 0.5 m rad. What is the dose equivalent in sieverts?
a. 0.5 m Sv
b. .005 m Sv
c. .05 m Sv
d. 5 m Sv
Answer: b. .005 m Sv
rem = rad x Q.
X rays and gamma rays have a Q about 1
Therefore 1 rem = 1 rad as Q=1
100 rem = 1 Sv
Therefore 0.5m rad= 0.5 m rem = 0.5 m /100 Sv= .005 m Sv
2. Determine the identity of the nucleus X in the reaction 13C6 + n -----> X + gamma
a. 13C6
b. 14C6
c. 14N7
d. 14N6
Answer: b. 14C6
n has a charge 0 and mass 1
gamma rays are radiation: no charge and mass
Therefore
X will have a charge = ...
