I work a great deal with x-rays producing art. www.x-rayarts.com and have plenty of experience with x-ray films. It's true that most ,edical x-ray films are coated on both sides but mammography films are single side coated. the catch to x-ray film is it's either high green sensitivity pr high blue sensitivity depending on the application and screen system used. Resolution of x-ray film, particularly double sised, is not as good as say HP5 which I use a great deal in my art. X-ray film for medical use is more light sensitive to the blue or green than to x-rays where as industrial is less sensitive to visible light and more to x-rays. In the medical industry an intensifying screen that fluoresces when struck by x-rays is used in a film holder on each side of the film (double coated film) and the screen either fluoresces blue or green depending on the screen. Most of the exposure is from the light not x-rays. In industrial use the film often has to be wrapped around a pipe or object and no screen can be used. In this case x-ray sensitivity is highest. To my knowledge all x-ray films have odd spectral sensitivity and may not even be orthochromatic. Contrast does tend to be higher and grain is not as good as photographic films. Resolution is lower too and this is why I use FP-4 and HP-5 for my applications where long scale and highe resolution with fine grain are needed to capture the finest details of my subject. My guess is it's not going to be very good for photographic use.

Aerials films are a better choice but do tend to be contrastier and have low blue sensitivity.
