A patient is given 0.055 μg of technetium-99m, a radioactive isotope with a half-life of about 6.0 hours. How long does it take for the radioactive isotope to decay to 6.7×10^(-3) μg? (Assume no excretion of the nuclide from the body.)

A patient is given 0.050 mg of technetium-99m, a radioactive isotope with a half-life of about 6.0 hours. How long does it take for the radioactive isotope to decay to 1.0 * 10-3 mg? (Assume the nuclide is not excreted from the body.)
A patient is given 0.050 $\mathrm{mg}$ of technetium- $99 \mathrm{m},$ a radioactive isotope with a half-life of about 6.0 hours. How long does it take for the radioactive isotope to decay to $1.0 \times 10^{-3} \mathrm{mg}$ ? (Assume the nuclide is not excreted from the body.)
