Final answer:
The question involves calculating the radiation dose from ingested zinc-65 by a physicist, considering several factors such as initial activity, decay energy, energy absorption fraction, body mass, and time frame.
Step-by-step explanation:
The question involves calculating the radiation dose a physicist receives from ingesting a certain quantity of zinc-65 (Zn-65). To determine the dose in millisieverts (mSv), one must consider the initial activity of the zinc ingested (measured in microcuries, µCi), the energy emitted per decay (in MeV), the fraction of energy absorbed by the body, the mass of the physicist, and the time over which the dose is accumulated (one day). The calculation involves converting the activity to disintegrations per second, finding the energy absorbed, and then converting that into the dose using appropriate conversion factors for energy and dose units.
