OH, BTW....Stainless don't ring....
on a pulse field walk through metal detector.....
industry secret from the early 80's.....
pulse field measures the decay of the magnetic field by the surrounding magnetic metals....but stainless don't react....
trick is that RF is so unstable in most operational shituations that it can't be trusted to screen typical personnel loads, say power plant workers, or airline passengers, or even courthouses......much less other .gov installations.....including the White House and Cap Hill.....Supreme Court.....
dunno much about today, except to say doubtful much has changed over the year, unless the did some krazy computer programming on a RF device to pick out the stainless.....witch is doubtful....
