Dutch Researchers Found that Wi-Fi Damages Trees

Share

Researchers from the Netherlands say that radiation from Wi-Fi networks has a negative impact on trees and can seriously affect the development of other plants.

A team of scientists at Wageningen University carried out a study back in 2005. They were asked by Alphen aan den Rijn officials who noted that ash trees growing near a wireless router had cracks and lumps. In addition, these trees lost their natural colors and had their leaves dying.

The team, led by Dr. A.A.M. van Lammeren, had a number of ash trees and some other plants exposed to 6 sources of radiation at frequencies that ranged from 2412 to 2472 MHz.

Researchers placed the plants at distances ranging from 50 to 300 cm for 3 months. They found that trees that were the closest to the source of radiation had leaves that developed a metallic luster and started dying off.

A current study of trees in the country showed that about 70 percent of all deciduous trees showed the same symptoms. This figure increased 7 times over the last five years. At the same time researchers found that trees growing away from urban centers remained uninfluenced.

It is worth mentioning that the results of the research could raise concerns regarding the installation of wireless routers in schools where Wi-Fi signals could affect not only trees but children as well.

However, scientists say that it is too early to make certain conclusions as more studies on a larger scale are needed.
