[ RadSafe ] Fw: [OEM] TIG Welding and Titanium face implants

Radsafers,

Just to get the conversation started - - Isn't TIG welding low voltage,
high current, with a small arc.  If so, how would significant microwave
energy be generated?   In addition, if this is an issue, couldn't the
welding mask be lined with a copper screen to shield the workers face
(half a Faraday Cage)??

Folks;

This was pulled off of another list I subscribe to.  Any of you have
experience with the NIR issues of welders that could comment?
