RE: (Fwd) Border gamma-xray devices
Yes, these devices are used at US Borders along Mexico and Canada and also
in ports, border checks, etc. As you can see from the SAIC website, there
are five different models for various applications. And yes, the doses are
very low. People are not intentionally scanned. However, if so the dose
received would be 5 - 10 uR depending on time distance and shielding, of
course.

Hi Pauline,
How are things going in Halifax ? Back on your feet after Juan`s mess ?
I found at least part of the answer while I was looking for something else
!!!!
Please see the following web site. The doses are presumed to be very low...
http://www.saic.com/products/security/relocatable-vacis/index.html
Now all we need to know is whether this device is indeed used at US Borders.
Perhaps Radsafers can help...

Subject: Border gamma-xray devices
I have received a question from a long haul truck driver who regularly
passes through the USA-Canada border. He states that he has to pass his
truck through a "gamma xray machine" and that he is "12 inches from the
machine when it is turned on and has to drive his truck through it at 1 mile
an
hour" My question is "Are these border devices detecting radiation or giving
off radiation?" and "How /or who could I write to get information about the
devices?"
Thanks
