A static field naturally produces no induction and hence no heating will arise. In the case 

of alternating fields the thermal effect in experiments is excluded by working with 

cxtremly low stimulations. The example after fig. 2.10 B shows the measured increase in 

the production (K) of colicin by colibacteria at only 0.01 mW/cm

2

 microwave power

.

 

In addition the example provides the interesting information that obviously only a certain 

frequency and it's harmonic waves increase the production, other frequencies on the other 

hand remain inactive. Because only minimal field strengths are used it more likely 

concerns an information-technical as an energetic effect (curve a). This statement is 

supported by the observation that an increase of the intensity not at all necessarily as a 

consequence also increases the production (curve b). What the colibakteria need is 

obviously neither energy nor heat but only a certain frequency that stimulates the colicin 

production or the growth.

 

Should it really be confirmed that biological effects of electric and magnetic fields can be 

produced by certain frequencies and can't happen by an energy transition so the 

discussions about limits must seem ample meaningless.

 

Maybe the one or the other in thought already draws a connection to the acceleration, the 

acclerated growth of kids, which is observed world-wide and stronger in cities than in the 

country. It started for approx. 100 years simultaneous with the electrification of the homes 

in the towns. In Asia the acceleration and also the electrification have started later. 

Other growth stimulating effects like radio waves, X-ray examinations, atomic tests and 

provable also the nourishment with vitamin B6 happened only until much later and at the 

most could support the actual effect.

 

But how should a proof be offered when anyway the field strength not at all can have a 

decisive influence on the growth of man after the statement of fig. 2.10 B? Which 

information is authorative? Where lies the responsible frequency window? Does the 

information actually manifest as frequency? Is the authorative influential factor also in this 

case not at all noticed and measured?

 

A lot of pressing questions are still outstanding. But in any case the numerous influential

 

factors detected in experiments do not at all let themselves reduce to a sole factor, for

 

instance the nourishment. For a family doctor it may be comfortable to be able to give an

 

easy explanation: ,,Cause is the nourishment!" With such a reductionism on the other hand

 

the actual cause stays in the dark and the asked questions in this way won't let themselves

 

be answered.

2.11 Artificial fields

 

The scepticism of people feeling close to nature is especially directed against artificial 

fields that man can't see nor hear nor smell. Objects of doubt are first of all the 

installations for the creation, distribution and conversion of electric energy.

 

An essential role plays the fact how close the supplying and the draining conductors are to 

each other, so that the respective fields can compensate each other. The worst solution one 

can think of is realized at the electrified railway. Here the rails and the earth are used as 

the draining conductor for the current while there exists an ample large distance to the

 

supplying conductor. A compensation is almost impossible thus causing gigantic 

interference fields that are detectable even at a distance of 10 kilometers. The increased 

putting on of railway engines feeded by rectified current is likely to aggravate the set of 

problems because the non-sinusoidal absorption of current is strongly afflicted with 

harmonic waves.

 

With high tension transmission lines (fig. 2.11) the interference field strength is reduced 

when the three cables are suspended with only little distance between them. But even the 

selected phase order can play a role. Of course the optimal compensation effect is

 

guaranteed with cables in the earth. But these are expensive and technically not realizable 

for such high voltage levels.

 

In the eighties also the computer screens got in the headlines. The terminals are furnished 

with a cathode ray tube and have a very broad radiation spectrum that already starts at 0 

Hz. Here already static maximum values of 64 kV/m are measured
