Hi Tom,
I’m the RSO at MPI Research in Mattawan, MI. I have a broad scope NRC license (Part 30 materials license) which covers all of our radioactive material uses (since MI is not an agreement state) and state registration for our various X-ray machines. We follow Part 20 requirements for work with radioactive materials and MI Part 5 for radiation producing machines. Since I have quite a bit of fluoroscope dose to contend with, I’m functionally locked in to quarterly monitoring. I can’t neatly separate the doses on an individual basis. But since power plants generally have no significant dose associated with X-ray machines, you can rely on your Part 50 license and use Part 20.

Fermi 2 and other NRC Licensed facilities are moving towards six-month dosimetry monitoring periods. When I stated that to an inspector from The State of Michigan he said that would be a noncompliance issue. He said Michigan Rules state that monitoring periods must not be greater then quarterly. Has anyone else run into this problem? Thomas M. Lashley, RSO Principal Radiological Engineer DTE Energy, Fermi 2 734-586-1697
