21. Nuclear Chemistry / Measuring Radioactivity / Problem 20
A radioactive isotope emits alpha-radiation with an activity of 11.2 mCi and each particle having an energy of 8.49×10–13 J. Assume a person weighing 65.5 kg is exposed to this radiation for 20.0 seconds and that 25.0% of the emitted alpha has been absorbed. Calculate the dose absorbed by the person in millirads and grays.
