ICNIRP – static fields

ICNIRP is the International Commission on Non-Ionizing Radiation Protection.  

ICNIRP issued new exposure guidelines for static fields in 2008 (although these new guidelines haven't yet been adopted in the UK - see UK static exposure limits).  As well as revising the exposure limits it reviewed the scientific evidence.  The section on laboratory studies concludes:

"In conclusion, current information does not indicate any serious health effects resulting from the acute exposure of stationary humans to static magnetic fields up to 8 T. It should be noted, however, that such exposures can lead to potentially unpleasant sensory effects such as vertigo and transient decrements in the performance of some behavioral tasks during head or body movement."

The section on epidemiological studies concludes:

"Overall, the few available epidemiological studies have methodological limitations and leave a number of issues unresolved concerning the possibility of risk of cancer or other outcomes from long-term exposure to static magnetic fields. These studies do not indicate strong effects of static magnetic field exposure of the level of tens of mT on the various health outcomes studied, but they would not be able to detect small to moderate effects. Other occupations with a potential for higher magnetic field exposures have not been adequately evaluated, e.g., MRI operators."

ICNIRP have also published a separate, longer, review of static fields.
