RE: [APML] Kinda OT - film through the mail problem

["Larry Geary" <larry.geary@att.net>]

As we've learned recently, most checked luggage is not X-rayed. So only one
of these rolls of film was likely subjected to X-rays, and that one was in a
lead bag, and it was pre-9/11. This really doesn't provide any assurance
about unprotected film under current security conditions.

One the people on our African eclipse tour had some interesting observations
about scanned and checked film:

"I used 4 rolls of Kodak Royal Gold ASA 1000 film in my experiment. The
first roll was a control, it stayed home and was not subjected to any
travel. The second roll was in a lead foil bag and went through all the
carry- on scanners we were subjected too. The third and 4th rolls were in my
checked luggage. One was in a lead mesh bag the other was unshielded. The
bag that contained these rolls was lost temporarily (2 days) between ATL and
ORD. So I don't know if it made any other airports in-between. This bag was
stored in Maun, Botswana while we were on Safari.
 Upon inspection of all 4 rolls there was no difference. I exposed the 1st
and 4 th frames. The first was a high contrast black letters on a white
background. The second I shot a Kodak color test bar against an 18% gray
background. There was absolutely no difference in any of the images.
  I am unsure of any of the airport scanners or what was done to any of the
checked baggage, so I'm not sure what my results mean. But from now on I'm
not going to worry about hand inspection of my film."
