As Rematog pointed out, the X-ray generator nature is what really exposes us to regulation. Some experience with the higher powered test rig will get us solid data on how long it takes to get a core back to background level radiation, our 2nd “exposure as I see it. Have you looked into IAEC and/or UN regulatory bodies?
I believe Eric’s estimate is that it would take about 9 hrs. for the external housing/maintenance space to return to background levels after shut-off. So it would take about a day to turn around each annual or semi-annual servicing.
