I am cleaning out my mail box and came across your comments on this item.
Is this the same as an ion sputtering device?  I surveyed one in our
building a few years ago and could not find any radiation levels above
background.  This is not included by our state (MD) in their regulations
as far as I can interpret them.  Just dropping a note - no reply needed.
