A \(75 \mathrm{~kg}\) patient swallows a \(30 \mu \mathrm{Ci}\) beta emitter with a half life of 5.0 days, and the radioactive nuclei are quickly distributed throughout his body. The beta particles are emitted with an average energy of \(0.35 \mathrm{MeV}, 90 \%\) of which is absorbed by the body. What dose equivalent does the patient receive in the first week?
