Dr Neil Cherry specialised most recently in the effects of electromagnetic radiation on human health, following his earlier work in meteorology and wind energy.

It is highly likely that Professor Cherry was the first Environmental Health scientist in the world to research and publish strong evidence that:

Electromagnetic fields and radiation damage DNA and enhance cell death rates and therefore they are a Ubiquitous Universal Genotoxic Carcinogen that enhances the rates of Cancer, Cardiac, Reproductive and Neurological disease and mortality in human populations.

Therefore there is no safe threshold level. The only safe exposure level is zero, a position confirmed by dose-response trends in epidemiological studies.

AND->
Solar and Geomagnetic Activity is a Natural Hazard causing serious human health effects through modulation of extremely small natural electromagnetic radiation (0.1pW/cm²), the Schumann Resonance signal, that is detected by the human brains...

and alters the melatonin output which causes modulation of many human health effects including cancer, cardiac, reproductive and neurological diseases and mortality.

EMF/EMR reduces melatonin in animals and people.
Dr. Neil Cherry, 2002

Dr. Cherry published research that opposed other research funded by Motorola in 2002. He called out the other researchers' techniques of experimentation as inaccurate.

Here is a link to Dr. Cherry's published research on EMF/EMR. It's quite an extensive archive.
