deciduous trees in the western world suffer from.
The findings come from
a recent study at TU Delft, TNO,
Alphen aan den Rijn and Wageningen University. The research was
driven by the municipality of Alphen aan den Rijn. Officials were

There was not a

Follow-up testing found the disease to occur throughout the western
world. In the Netherlands, shows no less than 70 percent of all
trees in urban areas the same symptoms. Five years ago, was only 10

researchers of the project also

The radiation came from a test facility
located in six WiFi access points. When the trees closest to the
radiation sources were, the leaves died. The experiment was done
with corn, which showed that the radiation inhibited the growth of

The Wageningen University has published
details of the tests. The report is not (yet) released.
"In a climate room notes and various
herbaceous plants for three months exposed to 6 radiation
sources (APs) at frequencies ranging from 2412 to 2472 MHz and a
power of 100 mW EIRP. At 50 cm to 300 cm. Initial observations
indicate a negative impact on the health of ash trees.
Leaves near radiation sources showed
at the end of the study period 'galena-like effects' that result
prove to be the death of the upper and lower epidermis of
leaves. The 'galena' is followed by dehydration and death of a
portion of the leaf.

cultures in identical climate rooms without radiation exposure.
Based on these first results is an
urgent need to proceed to trial repetition over a longer period

whether additional longer-term effects resulting from the tax."

TNO shows via a message on
his website know that the
organization has distanced itself from the conclusion that the
radiation from Wi-Fi has a negative effect on the health of plants
The research states that an employee on several occasions during the
study participated in discussions and feedback on test setups and
measurement results, but the conclusion regarding the relationship
between the two cases are not supported by TNO.
That conclusion is entirely borne by the

Is Wi-Fi Killing American Trees?

Wi-Fi systems are killing trees across
America. There may be no way to reverse the damage.
A study by Washington University in St. Louis confirms that Wi-Fi
radiation causes abnormalities in trees and these abnormalities
eventually lead to tree death. Trees that are exposed to the RF
(Radio Frequency) technology of Wi-Fi systems are dead within a year
The city of Joplin commissioned the
study five months ago. They wanted to figure out why their city’s
trees were developing weird growths, according to PC World. The
study, conducted by Nobel Prize winning Professor Gunnar
Hofverberg - the leading Wi-Fi expert in the United States, and
a world-renown arborist.
Hofverberg concluded that 95 percent of
trees in urban areas will die from Wi-Fi exposure.
“We studied tree bark, tree sap, and
the various insects that inhabit trees. They were all adversely
affected by RF. Botanists and arborists are extremely concerned
and feel that this is a national crisis of epic proportions.”
Hofverberg recommends banning all Wi-Fi
usage within a ten miles radius of any trees.
“It’s the only way we can save the
trees of America.”
The study exposed 900 ash trees to
various radiation sources for a period of three months. Trees placed
closest to the Wi-Fi radio demonstrated a “lead-like shine” on their
leaves caused dying of the upper and lower epidermis of the leaves -
and the ultimate death of the trees.
Additionally, he found that Wi-Fi
radiation causes squirrels to mate with chipmunks.
“Apparently, the RF radiation
affects the hypothalamus and the sexual synapses in the squirrel
brain,” said Hofverberg. “But the chipmunks seem to be
Additionally, on the west coast,
excessive Wi-Fi usage is causing forest fires.
“This seems to match our study,”
He also feels that Wi-Fi usage may cause
hurricanes and definitely contributes significantly to global
Hofverberg, who will be living in an ash tree for the next month,
will be beginning a study on shrubs in a month.
He’ll have results in ninety days.
Do Wi-Fi Signals Kill Trees?

No, they don't, a Dutch study finds. A
rumor that Wi-Fi signals sicken trees has been circulating the
Internet. It's not true, says a Dutch study.
It's an Internet rumor that is spreading, appropriately enough, like
wildfire: Wi-Fi signals can make trees and other plants sick,
causing cracks in their bark and killing off portions of their
leaves. The outlandish claim, supposedly based on a Dutch study,
cropped up late last week and has since been repeated in countless
In response, the Dutch government's
Antenna Agency, which provides information on the health effects of
electromagnetic fields, has issued a statement urging caution on the
unpublished, unverified and otherwise very preliminary findings.
As rendered via Google Translate, the Antenna Agency wrote (with a
"Based on the information now
available can not be concluded that the WiFi radio signals leads
to damage to trees or other plants."
Wi-Fi signals wirelessly connect
computers and other devices to the Internet.
The radio signals are similar to that
employed by other, decades-old technologies such as television and
cell phones, said Marvin Ziskin, a professor of radiology and
medical physics at Temple University.
"Stuff like this has been around a
long time... there's nothing new about Wi-Fi emissions," said
Ziskin. "Scientifically there's no evidence to support that
these signals are a cause for concern."
Nevertheless, officials in the Dutch
municipality of Alphen aan den Rijn tasked a researcher at
Wageningen University several years ago to investigate unexplained
abnormalities on local trees.
According to a write-up on the municipality's website, the work was
apparently commissioned with an eye toward the increasing number of
sources of electromagnetic radiation in the region, such as cell
phone tower masts.
In lab tests, leaves placed for a few
months near six radiation sources emitting radio waves in the 2.4
gigahertz range common for Wi-Fi and other wireless communications
became discolored and showed a,
"metallic luster appearance...
followed by desiccation and death of a portion of the leaf," the
Other reports have said that corn cobs
exposed to such conditions grew more slowly than expected.
The Antenna Agency statement suggests that the researcher involved
has backed away from the reported findings and has not succeeded in
repeating them (pardon the translation):
"The researcher from Wageningen
University indicates that these are initial results and that has
not been confirmed in a repeat survey. He warns strongly that
there are no far-reaching conclusions from its results."
More than 60 studies have looked into
the impact that electromagnetic mobile communications signals might
have on plants, according to an initial review by the Antenna
Some studies did find detrimental
effects, though likely as a result of signal intensities being high
(and close) enough to cause heat damage – not the situation in real
life with disparate sources of Wi-Fi signals.
Overall, the alarm raised by the
coverage of the tenuous Dutch findings is not unexpected, Ziskin
said, as health issues (primarily in humans and other animals, such
as honey bees, not vegetation) have frequently been attributed to
wireless radio signals and other low-level radiation. [Read: "Mad As
Hell - Airport Security Screening Protests Mount"]
"There's an awful lot of
misinformation and fear on this topic," Ziskin told
TechNewsDaily. "Anyone can drum up things like this to be
