A magnetic field is not radiation. The changing RF fields used are, but they're not ionizing radiation (the dangerous kind) like that found in CT scans. The radiation used in MRIs should not be able to induce any changes to the molecular structure of your body, but RF burns can still be a risk. (Clothing and even tattoo ink can exacerbate this, fascinating!) The biggest risk seems to be being bonked by loose medical equipment, but I don't think that's what you were asking about.

This - burns are actually more common than projectile injuries but a well run facility should have very few or zero of either.

There is a theory that there could be unexplored effects of RF exposure. For example, we can see that glucose metabolism increases in brain tissue exposed to RF. That could be the end of it, or there could be consequences to that under the right conditions. We don't know yet.
