Jerman I., Kustor V., Jeglic A., Fefer D. (1993): Subtle electromagnetic protection can have biological effects. Transactions of the 2nd EBEA Congress, Bled, December 9.-11.1993, pp 144-145.

To test biological effects of EM protection we used a special knitted fabrics with Fe fibres (12% of total weight). From 1 GHz to 10 GHz it weakened the field tfor 20-40 times; at 50 Hz the electric field was around 10 times weaker. In every experiment we used four different groups each comprising 150 seedlings and divided into three subgroups (50 seedlings). All seedlings were under mild and well-controlled dry-stress and controlled light regime. The subgroup dishes were weighed every day and watered to a constant weight. One group was completely protected for 16h/day and irradiated with microwaves (2.3 GHz, 0.05 mW/cm) for 10h/day. The second was sham-protected (same fabrics without Fe fibres) and equally irradiated, the third protected (as the first one) and non-irradiated and the fourth sham protected and non-irradiated. At the end of the experiment the lenght of seedlings roots and shoots was measured and statisticaly evaluated. We noticed significant even if variable, results. Out of 14 comparisons between the experimental groups we have 10 statistically significant differences (either stimulative or inhibitory). From this rather unexpecting finding we infer that the protection in habitual EM environment somewhat provokes the biological system of seedlings in a highly non-linear way. Thus it can sometimes enhance its powers to countract dry-stress and at other times. This means we must be very careful in making various protections against non-ionising EM radiation; they may bring their own biological dangers or at least irritations.
