5 Gauss Linegauss line
Body
was changed:
The 5 Gaussgauss line is the safety line drawn around the perimeter of the main magnet of the MRMRI scanner, specifying the distance at which the stray magnetic field is equivalent to 5 Gaussgauss (0.5 mT).
5 GaussFive gauss and below are considered 'safe' levels of static magnetic field exposure for the general public.
At 5 Gaussgauss and above:
- cardiac pacemakers and other implanted electronic devices are at risk of being interfered with by the static magnetic field
-
ferromagnetic materials may become projectile (and are thus prohibited from crossing the 5
Gaussgauss line)
Note that the distance at which a 5 Gaussgauss line is drawn around a particular MRMRI scanner will depend on magnet strength and the level of magnetic shielding used.
