Will there be radiation in a medical device factory that produces mr?

MR is electromagnetic radiation, high magnetic field 1.5T, 3.0T or higher, so far there is no evidence to say that the high magnetic field has any harm to the body, but in order to be cautious, it is still recommended not to stay for a long time in the place of the high magnetic field. mr factories are generally also protected by magnetic shielding, so it is not a big problem.
