CT and X-ray use vacuum tubs and electrical energy to produce x-rays as do linear acceleators.
However, PET, nuclear medicine, and certain procedures in radiation oncology DO use true radioactive materials.
MRI utilizes radiofrequency energy to produce images.
Exclusive of MRI, all of these machines produce radiation however most of them don't USE radioactive materials. Because of this, x-ray doesn't leave residual radiation after the beam is turned off. Once the beam is off, there is no contamination of the patient.

None of them make radioactive substances
X-ray machines make X-Rays in a vacuum tube and direct it at bones and the rays that make it through the body expose a film, like in photography.
MRI. uses magnetism to to make images on sensors (nothing radioactive here.
CT scan is another imaging device, it does not produce radioactive products, but may contain a radio-active source for the scan.
As far as I know, only neuclear reactors and cyclotrons create radioactive material.

You betcha. An MRI is not a radioactive machine. It uses magnetic energy. Xray = radioactive (when the switch is flipped).

There are many new X-ray machines that do not use radiation to make x-rays or very low x-rays. You might go to web MD and do a search for them there.

Can they attempt this?! that would clarify why I set it off very last time. I were given felt up through a secure practices lady, and my kinfolk were on the different area, giggling at me. i concept it would were the eyelets in my shoes. actual now i imagine about it, i imagine I wasn't donning shoes because they make you're taking them off.
