Re: IR film & X-Rays ?

["Thomas H. Hogan" <flzhgn@xxxxxxxxxxxxx>]

My Kodak High Speed film both exposed and unexposed has not been
affected by going through the X-ray machines at airports.  Neither
has my Tmax P3200, Kodachrome, or Ilford XP2.

X-ray film is usually used with a special intensifying screen that 
fluoresces when it is hit with X-rays.  Zinc Sulfide screens used to
be used in the old days to visualize X-rays.

Since photographic film does not have x-ray fluorescent materials 
associated with it, and there is almost no interaction between the
silver halide in the film and the X-rays, there won't be a problem.

Making an X-ray image is not easy!  You need an intensifier screen
or an extremely long exposure and high activity developers.
