If you are going to go to the trouble of using dry plates you might as well set up your own dark room as well. Professional camera shops may be able to help you out with finding a place that will do them for you but it is an old method and usually done by the same person who took the photo. Even in 1976 when I was using my grandfathers 8x10 and 4x5 cameras and cutting my own film from 11x14 stock, places were hard to find and I converted a bathroom in my parents house ( much to their chagrin ) into my darkroom. The chemicals were much easier to find than someone to do it and I pretty much wanted to do it all myself anyhow. If these are old undeveloped plates that you found and you want to find out what is on them again your local professional photo shop might point you toward some photographic artists or black and white enthusiasts in your area.
X-rays will "Fog" photographic plates. That means the plates act as if 'exposed' to light. If the X-rays are intense enough, the plates will appear to be totally exposed.
For photographic plates silver halides are used.
That's because photographic plates are sensitive to light.

Photographic plates or films can be destroyed in direct contact with plutonium.
Henri Becquerel discovered it by accident when some photographic plates were left several days in a drawer with some ore samples containing uranium. The plates were not exposed to light, but when developed, the plates showed they had been exposed to something. More experimentation by Becquerel showed that this was radioactice decay of the uranium.

The first evidence of nuclear energy was found in the late 1800s when a scientist found that sealed photographic plates that he had left in his desk drawer with some rocks were fogged when developed. This effect (of the rocks on the plates) was called radioactivity. It took many experiments to find ways to get this energy on demand.
