What About Electromagnetic Emissions?
There has been recent public discussion of the possible health effects of prolonged exposure
to extremely low frequency (ELF) and very low frequency ( VLF) electromagnetic fields. Such
fields are associated with electromagnetic sources such as television sets, electrical wiring,
and some household appliances—as well as computer monitors.
Apple has reviewed scientific reports and sought the counsel of government regulatory
agencies and respected health organizations. Based on the prevailing evidence and opinions,
Apple believes that the electric and magnetic fields produced by computer monitors do not
pose a health risk.
In response to those customers who wish to reduce their exposure to electromagnetic fields,
Apple has lowered the emission levels of our products. We are also actively encouraging
further scientific research so we can continue to promote the health and safety of our
customers and employees.
