    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 = ...
