officials in the town of Alphen aan den Rijn in the Netherlands
began noticing unexplained abnormalities on trees,
they were worried that the damage did not come from natural
were concerns that cracks, discoloration, tissue deterioration
and other problems stemmed from radiation fueled
by area Wi-Fi networks.
town commissioned Wagenigen
University to conduct a study to determine the source.
The study concluded that radiation from Wi-Fi networks may have
negatively impacted the health of nearby plants. Three
months of research found outbreaks of bleeding
bark and dying leaves on a large number of Ash trees and a
slower rate of growth in corn plants near area
hotspots. Leaves within 50 to 300 centimeters of a
100 milliwatt, 2412-2472 megahertz radiation source showed “a
metallic luster appearance, a discoloration of the leaves that
appeared to result in the disappearance of the outer cell layer of
the leaves. The metallic luster was followed by desiccation and death
of a portion of the leaf.”
Dutch Antenna Agency indicated that the same adverse effects have
not been found on other species of trees and that the
abnormalities discovered on the trees at Alphen aan den
Rijn may have simply come from disease.
repeat study did not determine the same conclusions. While
the study to be inconclusive and further research is
expected, the full report will be under discussion at
a February 2011 conference.
