Model		ICNIRP Exposure Guidelines (RF + ELF)
Details		ICNIRP Exposure Guidelines (RF + ELF) Static Magnetic Field exposure: occupational acute exposure limits 2 T (same as prior recommendations) for the head and trunk and 8 T (increased from 5 T) for the limbs. The 2 T limit for head and trunk is set to avoid nausea and vertigo. General public acute exposure limits 400 mT for any part of the body (increased from 40 mT - time averaged from prior recommendations). Time-averaging was eliminated from the prior 1998 recommendations based upon evidence (MRI workers, etc) that since all established effects are due to acute exposures. Potential mechanisms of static magnetic fields include magnetic induction (charged particles flow to opposite pole), motion within a static field that induces an electric field (responsible for vertigo, nausea, and phosphenes), magneto-mechanical interactions field gradients exert forces on paramagnetic and diamagnetic materials), and (hypothetically) electron spin interactions that might change the activity or structure of proteins and biological chemicals.
