Yes, but you want 'soft' x-rays as used for tissue imaging, not the 'hard' x-rays used by welding inspection (but the latter is MUCH faster). Depending on part and source (dental x-ray) 30s to 2mins. This time is hard on the dental machine since it's designed for sub 1 sec exposures. I would suggest starting with 10s and then go 3x whatever time first causes bits to disappear.
