i got LSD in the mail once and it came in one of these X-ray proof bags (http://www.xrayproofbags.com/wp-content/uploads/2012/10/nice-bag.jpg).
what i want to know is what do these bags show up like under an X-ray? do they show up as nothing at all? or do they show up as a solid block?
im wondering cause if LSD blotters are just paper if the x-ray proof bag shows up as a block that might look more suspicious then just putting the tabs in plastic to keep it from air and putting it with other papers. but if the x-ray proof bags show up as nothing at all then its probably a good idea.
You can't get X-ray-proof bag. What's it made out of? Black hole?
I used to work with 59 KeV X-rays, and they were only partly-attenuated by the sticky-backed lead sheet we stuck on everything, which required tin snips to cut.
The bag will just be to prevent the blotters getting wet. If it's metalized, thats just to prevent static electricity from damaging electronic components that are sometimes packaged in it.
You want stuff to be transparent to x-rays, not opaque. It would look like somebody posting a lead rectangle if such a material existed.
X-rays are attenuated by mass, so you would need the same mass of hydrogen or of lead per square meter to give the same attenuation
