Maybe but the $ saved probably not worth the risk in my opinion.X-ray radiation should only occur while the X-ray machine is actively running. Otherwise the x-ray equipment would keep exposing healthcare workers and techs to radiation, and I doubt OSHA would allow this. Even though radiation might not be a problem here, breathing any dust while turning is bad for your health. Also, using these as outfeed rollers would produce no plastic dust.
Your question was an interesting thought, but according to several government sources there’s no residual radiation risk unless it’s coming from the X-ray tube while it’s energized. These rollers look like part of a film processor so the rollers might need a good cleaning. Nothing that I would be worried about since they look pretty clean. Just saying there’s no radiation hazards with x-ray equipment just in case someone else is wondering.

:) I was self employed for 25+ years- you assume government is on top of this. Me.... I will pass.... I live in state that has hanford- first Nuke facility - facts have changed here yearly....Your question was an interesting thought, but according to several government sources there’s no residual radiation risk unless it’s coming from the X-ray tube while it’s energized.

So the rollers showed no reaction, nor did the stainless steel. I was just told the x-ray film machine that these rollers are from was in a different room than the actual imaging machine. So the only radiation would be any that leaked (made it beyond the lead walls), from cell phones or if any is produced when developing film.Whenever you get a chance is good with me Mark, thanks.
Yes please, thanks Mark.So the rollers showed no reaction, nor did the stainless steel.

So, am I filling a medium box for you?
i personally set off the radiation detector one time at the scale entrance at the scrap yard. i had had a medical heart stess test, (chemical induced), 2 days prior. the chemical radiation signature was enough to set off the drive through radiation detectors mounted on either side of 10 foot wide vehicle scale.I am no radiophysicist or nuclearphysicist, but I be a corntractor who has built and demolished a number of x-ray (more correctly - Roentgen-rays) rooms, labs, suites (as well as some of the deep therapy and linear accelerator rooms for cancer treatments - ask me about the $1,000 per cy concrete sometime) and asked a number of "expert" and even used a geiger counter once on a demo of some big labs - just to be on the safe side (I had the lead lining of the rooms scrapped and used the $3K it earned to put on 2 bbq's for the workers - It was a sizable 21 story MOB project). Without going thru a long explanation, firstly, these rollers are said to be from an x-ray photo machine - would be more correctly called an x-ray film developing machine - very, very similar to the photo developing machines in all the drugstores, and big boxes before the widespread use of digital cameras. In fact, there is not all that much difference between B&W film and X-ray film. The film was exposed on the x-ray machine, and then transferred to the developing machine in a lead lined cassette.. Because the developing machine contains some undeveloped and partially developed film, it had to be shielded from the x-ray machine. They were usually in another room or behind a lead-lined partition. The only thing in the machine that would have been exposed to the x-rays would be the film - and that brings on the second point. Diagnostic X-rays don't make things radioactive. An x-ray tube is like a light bulb: when you turn it off, the light stops. This is true for a plain x-ray, for a CT scan, and even for a radiation therapy machine: when the tube is turned off, the radiation is gone. It does not persist in the body; you will not be exposing anyone else if you come near them, and you will not set off a Geiger counter if you walk by it. That's not to say the tissues aren't reacting while the machine was turned on, they are and it takes some time for that reaction to finish. The effects of radiation therapy could continue to evolve over several months with some of the very strong "radiation" therapies, but that’s not because the radiation persists; it’s because; it’s because the tissues are reacting to biochemical effects on the cells and molecules done while the machine was turned on.
An x-ray is ionizing radiation which is radiation strong enough to remove an electron from an atom. Radioactive means a nucleus that is unstable and decays by emitting nuclear radiation. X-rays are electromagnetic radiation that occurs due to a electrons changing energy levels. X-rays do not come from the nucleus and are not defined as radioactive.
On the other hand, there are imaging procedures and treatments which involve administering a mildly radioactive substance to a patient; and in that case, the radiation will persist in the patient’s body for a period of time. These are generally radioisotopes made by much, much more powerful energies - the kind produced by a cyclotron, for instance. Then certain elements are "turned into" radioactive isotopes for “nuclear medicine” studies. Totally different ballbark. You cannot turn off nuclear-derived radioactivity. i.e. if those rollers had been exposed to, say, a cycloton's beam - then that is a different story altogether.
X-rays consist of high frequency quantized photons. Visible light consists of the same quantized photons except at a lower frequency. They don’t hang around. They leave the x-ray room at 300,000,000 meters per second (ok approximately). Without shielding, those photons are past the orbit of the moon about a 1 1/3 second after you turn the machine off.
All in all, except for the possibility of chemical residue from the developing chemicals, I'd sleep next to the rollers and if all those are cleaned up then no problem.
BTW - CT, MRI, RIT, PET rooms have their own challenges to build.
