"....Well gentlemen,
I just got off the phone with my freind who is an x-ray tech for many years now(going over 25 that is), and he has informed that carbon paper does in fact distort the object that it is wrapped around, but does not totally make the object invisable to the x-ray.
Example given--If u were to take a CD(4 distinct edges) and wrap the CD in the carbon paper and shoot a film of it, it will lose it distinct edges, u will be able to tell that there is something there but it will blend into the film.
I'm a physicist whose field deals with imaging, I'm not sure but I'd assume customs uses a fluroscopy (sp) type machine which uses longer wavelength x-rays as compared to normal x-ray machines people are usually familiar with. But, even with these lower energy x-rays, carbon paper will not cause "blurring" by attenuating any incident radiation. However, if u wanted to, I would get real tin foil and place amps, etc. inside tin foil which has been shaped into something which would not raise susspecion. Tin has a high enough atomic weight to cause some sttenuation of lower energy x rays. Now this is off the top of my head, but I KNOW I could determine how to shield (fuck up) the transmission of x rays which would conciel what you would be sending....."

What is the Difference Between Carbon Paper and Carbon Cloth Based Gas Diffusion Layers (GDL)?...
they also do not chip or break as easily as Toray paper while still being available in thin sizes. Some GDLs are very hard and brittle with little compressibility (e.g. Toray); others are much more pliant/flexible but still don’t have much compressibility (e.g. Sigracet, Freudenberg). Also, papers may or may not have Microporous Layers (MPL) and/or additional hydrophobic (Teflon) coatings.
...sometimes with old X-ray films use to blur the contours of the object
