Dear Glenn,
This is a very relevant issue for a high-resolution NMR lab anywhere! A
couple of NMR labs I have been to do not allow shoes other than dedicated
slippers inside the MR room. The easiest solution would be a bench across
the entrance door-way with personal (as well as guest) slippers.
An MRI-lab is somewhat more problematic, and we find regularly objects of
NMR-inappropriate nature inside the magnet (nails, pens, paperclips, etc).
73, Peter
