NOTE2 As of 2017, many things are still not known about the effects of prolonged exposure to strong magnetic 497 field on the human body; however, epidemiological studies and animal experiments have raised the possibility 498 that damage can occur. With regard to demonstrated effects on humans, there are known cases of pacemaker 499 malfunctions in magnetic fields of 0,5 mT; therefore, the boundaries of the zone around the superconducting 500 magnet where the magnetic field is ≥0,5 mT shall be clearly indicated. 501 502
