Assume that there was no external contamination at the time of the first body count. E. An isotopic measurement is performed on an air sample after the incident. Show all work. You are the health physicist at a university with a research reactor. You note that 41 Ar is produced in this reactor by activation of natural Ar dissolved in the pool water and in air-filled voids near the core.
Some experimenters also produce it intentionally for use as a tracer.
All of the 41 Ar is released to the reactor room. The reactor room ventilation fan exhausts at the building roof level. It operates during and after the event. The 41 Ar mixes uniformly with the air in the reactor building immediately after the release. Show all work.
