Geomagnetic Fields

A �Magic Bullet� Mechanism

It is well established that whilst epidemiology has linked exposure to magnetic fields and power lines to numerous health effects, definitive explanations of such links have remained elusive. Literature has previously linked exposure to other environmental sources such as light and power-frequency magnetic fields, with increased risks of certain cancers amongst other health effects.

This area of research is exciting as it incorporates the influence of light, geomagnetic and power frequency fields. The primary candidate mechanism is the Radical Pair Mechanism (RPM).

The Earth�s Magnetic Field

Fluctuations in the level of the Earth�s Geomagnetic Field (GMF), a quasi static magnetic field, and geomagnetic storms have been associated with a number of health effects and disorders in scientific literature spanning more than 50 years.

Why Look at Magnetoreception?

Aldrich, Andrews and Liboff (2001) � The results � offer evidence that a metric of EMF�s, incorporating a geomagnetic component, may finally provide some clarification on the protracted quandary about EMFs and cancer risk.�

How does the GMF interact with life on Earth?

What are the Reported Effects of GMF Interactions with Humans?

Literature has suggested links to

Semm 1980 � Effects of an Earth-strength magnetic field on electrical activity of pineal cells. After initial exposure to 50�T and diminished pineal electrical activity was observed, it was possible to depress activity again with a low stimulus of 0.10�T.

The pineal gland is the adrenal gland responsible for the synthesis of the hormone melatonin which is a well-established free-radical scavenger. It also plays an important part in establishing and controlling the �body-clock� or circadian rhythm.

There is evidence from Norway of exposure to temporal changes of the GMF and Melatonin Suppression:
