་
Part A
131 I undergoes beta-minus decay with a subsequent
gamma emission from the daughter nucleus. Iodine in the
body is almost entirely taken up by the thyroid gland, so a
gamma scan using this isotope will show a bright area
corresponding to the thyroid gland with the surrounding
tissue appearing dark. Because the isotope is
concentrated in the gland, so is the radiation dose, most
of which results from the beta emission. In a typical
procedure, a patient receives 0.050 mCi of 131I. Assume
that all of the iodine is absorbed by the 0.15 kg thyroid
gland. Each 131 I decay produces a 0.97 MeV beta
particle. Assume that half the energy of each beta particle
is deposited in the gland.
What dose equivalent in Sv will the gland receive in the first hour?
Express your answer with the appropriate units.
