Guidelines on Limits of Exposure to Static Magnetic Fields

The International Commission on Non-Ionising Radiation Protection (ICNIRP) has
published 'Guidelines on Limits of Exposure to Static Magnetic Fields'.

The rapid development of technologies in industry and medicine using static
magnetic fields has resulted in an increase in human exposure to these fields
and has led to a number of scientific studies of their possible health effects.
The World Health Organization (WHO) recently developed a health criteria
document on static electric and magnetic fields within the Environmental Health
Criteria Program (WHO 2006). The document contains a review of biological
effects reported from exposure to static fields and, together with other recent
publications [mainly International Commission on Non-Ionizing Radiation
Protection (ICNIRP) 2003, McKinlay et al. 2004, and Noble et al. 2005], serves
as the scientific database for the development of the rationale for the
guidelines described in the current document, which supersede those published
by ICNIRP in 1994 (ICNIRP 1994).
