Does Low-field NMR Has Radiation Damage？ No, NMR has no radiation damage. NMR is different from X-ray generator and CT in principle. X-ray generator and CT all need the X-ray to irradiate tissue and accept the X-ray which has absorbed by tissue to obtain the information. X-ray is the source of the man-made radiation damage. The principle of NMR is using a RF pulse to inspire H proton in high magnetic field to create the NMR signals. The process won’t produce high energy radial, the word nuclear of NMR is refer to H proton, without relationship with nuclear radiation,so NMR has no radiation damage. Low-field NMR instruments’ magnetic field is lower than 0.5T. NIUMAG’s magnet has thickening iron shield and special made magnet cabinet. It prevents the magnet field disseminating, the m...
