Alice Stewart & harmfulness of low-intensity EMR (15/7/02)
Tramès per Klaus Rudolph (Citizens'
I very much appreciate that Alasdair Philips passed along the story in
the UK Guardian (June 28, 2002) by Anthony Tucker on the life and work
of Alice Stewart
As I was reading it, I was reminded that my own work on the health effects
of non-ionizing radiation (done from a hygienic perspective) has implications
for ionising radiation, as well. In fact, I think Alice Stewart
long ago discovered them!
Here is my thinking. For non-ionizing radiation, there are two kinds
of health effects (which have different mechanisms): thermal & nonthermal
(also called athermal). Increase the photon energy enough to allow ionization
to occur, and then (for ionising radiation) there are three ways to damage
health: ionization, nonthermal effects, and thermal effects.
My point is that in the ionizing region of the spectrum, the same mechanisms
and health effects exist as for non-ionzing radiation; there is just an
additional mechanism of hazard (ionization) added to the mix.
To date, my only publication addressing non-ionizing health effects is
Chapter 4 in WIRELESS PHONES AND HEALTH II: STATE OF THE SCIENCE
(published in 2000 by Kluwer Scientific Publishers, NY). In there I show
how different the thermal and nonthermal health effects are, in terms
of the conditions under which they appear.
These same health effects can be expected to be present in the ionizing
portion of the spectrum, along with the well-known health effects of ionization.
I show that nonthermal health effects are likely to occur at very low
radiation intensities (and will include cancer). These are quite
unexpected, if one uses thermal effects to predict hazard (which many
authorities do indeed do).
What did Alice Stewart find? That there is an unexpectedly high health
hazard at very low intensities which includes cancer. This was unexpected,
based on the assumption that ionization is the only mechanism of hazard
from ionizing radiation.
What do thermal effects (for non-ionizing radiation) and ionization (for
ionizing radiation) have in common? Both these phenomena give rise
to a health risk that is monotonic increasing; that is, as the radiation
intensity or field strength (for non-ionizing radiation) or the amount
of ionization (for ionizing radiation) goes up, the health hazard increases.
This implies that there is a certain level below which everything should
Alice Stewart found out that, for ionizing radiation, there is a health
hazard at low levels thought to be safe. I think it is the low-intensity
nonthermal hazard I discuss in my publication. So, in effect, I
think she long ago proved the existence of what I (and others) postulate
is a health hazard in the non-ionzing portion of the spectrum.
Of course, since this hazard has nothing whatever to do with ionization,
it ought to exist for electromagnetic radiation at all frequencies in
the RF region of the spectrum AND ALL HIGHER FREQUENCIES!
The very fact that the low-intensity radiation hazard Alice Stewart found
was unexpected is an indication that it was NOT caused by ionization!
The only phenomenon that could have given rise to it is the same non-thermal
phenomenon that we are concerned about with respect to microwave and other
RF radiation. So I consider that Alice Stewart long ago proved the
existence (in the ionizing portion of the EMR spectrum) of a low-intensity
nonthermal health effect (that includes but isn't limited to cancers of
various types) and therefore these same health effects can be expected
to occur at similar very low radiation intensities in the non-ionizing
portion of the EMR spectrum!

Cellular Telephone Russian Roulette
A Historical & Scientific Perspective
By Robert C. Kane, Vantage Press, NY, ISBN 0-533-13673-3
In depth analysis of the safety issues regarding cell phone usage. Well
documented with abundant references and clearly written for the average
reader. If you had doubts about the safety of cell phones before, this
book will convince you (and anyone else) that cell phone use is dangerous,
that the cell phone manufacturers know it, and that there is an intentional
cover-up of the facts. Must reading for parents whose children have cell
phones. 235 pages, 2001.
