Electromagnetic fields are waves that transport energy through space. They are characterized by wavelength and frequency, the two of which are inversely correlated. The
shorter the wavelength, the greater the frequency.
Electromagnetic fields include the following (in order of decreasing wavelength and
increasing frequency): electromagnetic fields of extremely low frequency (from electric
sources), electromagnetic fields of low frequency, electromagnetic fields of radiofrequency and microwaves (from mobile telephones, television antennas etc), ultrasounds,
infrared rays, ultraviolet rays, X rays and gamma rays. Gamma rays, given their energy
charge, are also defined as ionizing radiation, and are capable of altering genetic cellular
material. Indeed, the carcinogenic effects of ionizing radiation have been known for
decades.
Scientific data regarding the long-tenn effects, in particular carcinogenic risk,of the
exposure to non-ionizing electromagnetic fields were not reported in the literature until
the 1970s. In 1979 two Amcncan researchers, Wertheimer e Leeper, published for the
first time the results of an epidemiological study that demonstrated an increased carcinogenic risk, specifically leukemic, in children residing in close proximity to electric
installations and therefore exposed to non-ionizing electromagnetic fields from electrical
current at extremely low frequency.
As was to be expected, concern about the possible carcinogenic risks of non-ionizing
radiation has now expanded beyond electricity to include other types of non-ionizing
radiation, such as electromagnetic fields of radiofrequency and microwaves from
cellular telephones and other wireless technologies such as cordless telephones,
computers etc.
Thc cxpansion of mobile telephone technologies in the last 10 years is without precedent. In 1996 the number of cellular telephones in Italy was circa 4 million, today this
figure is estimated to be 40 million. In the US, cellular telephones in the 1990s numbered
9 million, today more than 150 million Americans use cell phones, including children.
It is estimated than more than 2 billion people use cell phones worldwide. In addition,
many citizens are exposed toelectromagnetic fields originating from the antennas of
radio base stations that transmit cellular signals. Indeed, exposure to electromagnetic
fields of radiofrequency and microwave, in both the work and general environment, has
never before experienced this type of growth. For this reason it is fundamentally important to address the issue of safety, using all available tools to evaluate the potential risks
of exposure. These tools include both epidemiological and experimental laboratory
studies. as well as basic research.
hisb book provide updated information concerning mechanism of interaction between
uon ionising radiation fields and living matter, with particular reference to potential nonthermal toxic effects

The scientific knowledge available today regarding electromagnetic fields remains
limited. Nevertheless, on the basis of recent epidemiological studies, and while awaiting
new experimental data, it is advisable to limit exposure to electromagnetic fields as
much as possible. This is especially true for children and adolescents, the most wlnerable segments of the population, and has been recornmcnded by both the Swedish and
UK health authorities.
Why investigate the non thermal mechanisms and
effects of electromagnetic fields on living systems?
An introduction

A Fairy Tale
Protection against Non Ionizing Radiation is based on a paradigmatic assumption:
"We know v e y well the interaction between electromagneticfields and living oi.ganisins: it is a thermal interaction; thus the standards inter~zationallyaccepted are
adequate to protect people and workers "'.
This is a fairy tale.
Since the 1970s the non thermal effects of electromagnetic fields on living organisms
have been well known and also the non thermal mechanisms have been investigated2,'.
Nevertheless, until today, we have been condemned to listen to representatives from
international institutions repeating the old refrain above. Furthermore when scientists
participating in the ICEMS agreed to edit a monograph - the present one - with the aim
of illustrating the non thermal mechanisms and effects due to the electromagnetic intcraction with living organisms - mechanisms that are well known today - some of us withdrew their contribution because they did not share the locution "nun thermal" in the title.
The following discussion, which many ICEMS scientists and the coauthors of this
monograph took part in, focused on some basic points, maybe obvious hut not infrequently forgotten.
To be able to speak about a thermal effect on a system, we must first observe a variation in the temperature of the system.
Temperature
In order to define the temperature of a system it is necessary to include the philosophical concept of ensemble:, in extension a collection of independent and indistinguishable particles each having a well defined velocity. In such a picture the temperature will emerge as an average property of the system as the avcrage kinetic energy
defined on the ensemble. In the case of a biochemical system made up of many nonindependent particles the very basic concept of temperature has to be defined through an
ovcrsimplitication of the system description (useful in most applications): we assume
that each ~noleculccan be labelled with a mean velocity energy which, in turn, defines
an average energy associated with each degree of freedom of the molecule itself. In such

a picture a perturbation is termed "thermal" if it is able to change the average kinetic
energy associated to each degree of freedom, in such a way that the average of the energies on the ensemble is changed.
The rotating motion of water molecules induced by microwaves is the most evident
achievement of such a thermal effect, but we need not think it is unique. In our monograph we focus on an effect - the coupling of RFIMW with cancerous tissues - discovered by E.H. Frick and S. Morse (1924) and re-discovered by C. Vcdruccio, as reported
in this monograph.
The Energy transfer mechanism described by the classical or semi-classical model of
biological matter is based on "hopping" along discrete energy levels. However, as is
widely known in the literature, such a model cannot account for the energy transfer
process in biological systems such as photo-synthesis, where the light-absorbing molecules can funnel energy with a near-unit quantum efficiency across mesoscopic
distances. Such a conundrum implies a deeper re-thinking of the molecular biology
model based upon independent and indistinguishable particles. The solution implies a
high degree of correlation among a great number of molecules and the enhy in play of
quantum phenomena. Quantum mechanics teaches us that energy transfer can happen in
a quantum-conelated system without entailing kinetic knocks.
Non Thermal effects
In such a picture it is paramount to distinguish between "thermal" and "non-thermal"
effccts. In fact, the existence of the latter implies a model of biological matter well
beyond the classical or semi-classical representation. Hence the deep meaning of the
thermal-non thermal querelle : to minimize this distinction could lead us to underestimate what is probably the watershed of modcm biology.
However, because we are concerned with biology or biophysics - not atomic physics
- we may be focused on much more coniplex systems than atoms and we may fail to
monitor the variation of energy of single electrons or single atoms. Even an aqueous
solution of aminoacids, in a quantity such as in the electrolytic cell of Zhadin described
in this monograph, has millions of billions of billions of molecules, as Avogadro taught
us. Thus wc should not be deceived by the fact that a certain molecule rcceives cnergy
during a reaction into concluding that this reaction is based on a thermal mechanism of
interaction. We must look at the temperahlre of the system. We must observe the system
and the average of the energies of all components involved.
For instance, in the aqueous solution of the Zhadin experiment, we witnesss an ion
currcnt peak - that can be detected in the order of 10-100 nA - when we apply a suitable
combination of DC-AC magnetic fields. But the AC field is very weak: in the order of
lOnT! And the DC field is like the geomagnetic one: there is no transfer of energy able
to induce an alteration in the system temperature. It is not only a non thermal effect; it
is an athermal effect!
ThermaliNon thermal in EMF risk assessment
Lastly, let us consider the current meaning of 'thcmial effects' in RFIMW risk assessment. According to ANSI (1981), interactions inducing a temperature increase lower
than 0.5 OC i n the human body are commonly accepted, even by the WHO. The corresponding value in temls of of WHOLE BODY AVERAGE SPECIFIC ABSORBTION
RATE (WBASAR) is 4 Wlkg. Furthermore, the absorption of 0.4 W k g - corresponding
to a temperature increase equal to a 0.05"C in the body - is considered negligible for
workers and the absorption of 0.08 W k g - col~espondingto a 0.01 'C increase - seems
to be negligible. WHO, IEEE and ICNIRP assure us that under such a threshold we can
he protected against all health effects due to RFlMWs. On this vicw, biological non
thermal effects are only to be considered as reversible effects. Bur non-reversible effects
are detected under the samc threshold by epidemiologists -see the assay by Lennart
13ardell in this monograph -: such effects can be considered 'norz thermul' effects in this
context. What about mechanisms inducing temperature increases lower than 0.001 "C
(co~~esponding
to 0.008 Wlkg SAR)? They can be considercd 'non tl~ertnal'in the same
context, in accordance with the usual convention that perturbation of a system, whcn the
parameters are lower by threc orders of magnitude than the corresponding parameters of
the system, can be considered not related to such parameters.
Perhaps we should specie the meaning of thc tenns thennallnon thermal in the
present monograph. With reference to the usual meaning adopted in the context of
protectio~tagainst radiation, we can consider as non thermal all n~echanistnsthat arc
not able to induce an increase in temperature higher than 0.0l0C, when we are considering a system like a living organism, or lower than 0.001 "C when a system like a cell
is considered, or again lower than 0.0005 O C when a sub-cellular system is studied.
Several mechanisms and effects are considered in this monograph with the collaboration of many scientists who have joined this ICEMS initiative.
Our book does also include thermal mechanisms and effects as well as macroscopic
phenomena (see the various sections of the book)
The point is, protection against non ionizing radiation, based on parameters adopted
by international standards organizations, seems not to be adequate, despite the statement
of Ms Van Deventer, nor able to protect people and workers. This 1s convincingly shown
in the paper by Devra Davis, Om Ghandi and colleagues in this monograph.
