It started with an observation and a question. The girls noticed that if they slept with their mobile phones near their heads at night, they often had difficulty concentrating at school the next day. They wanted to test the effect of a cellphone’s radiation on humans, but their school, Hjallerup School in Denmark, did not have the equipment to handle such an experiment. So the girls designed an experiment that would test the effect of cellphone radiation on a plant instead.
The students placed six trays filled with Lepidium sativum, a type of garden cress, into a room without radiation, and six trays of the seeds into another room next to two routers that according to the girls’ calculations, emitted about the same type of radiation as an ordinary cellphone.
Over the next 12 days, the girls observed, measured, weighed and photographed their results. By the end of the experiment the results were blatantly obvious – the cress seeds placed near the router had not grown. Many of them were completely dead. Meanwhile, the cress seeds planted in the other room, away from the routers, thrived.
The experiment earned the girls (pictured below) top honors in a regional science competition and the interest of scientists around the world.
According to Kim Horsevad, a teacher at Hjallerup Skole in Denmark where the cress experiment took place, a neuroscience professor at the Karolinska Institute in Sweden, is interested in repeating the experiment in a controlled professional scientific environment.
If this is a repeatable experiement, it could change the way we use technology and make us all safer. It is now 2018, was this experiment ever repeated?
A similar study was conducted about three years ago in the Netherlands when researchers noticed that some trees in urban areas were showing “bark lumps,” according to Popular Science. The experiment, conducted by Wageningen University, involved exposing 20 ash trees to various kinds of radiation for three months. The trees chosen to test tolerance to heavy WiFi signals began to show typical signs of radiation sickness, including a “lead-like shine” on their leaves.
As for the attention the girl’s science fair project is getting, Horsevad said neuroscience professor Olle Johanssen with the Karolinska Institute in Sweden has expressed great interest.
“[Johanssen] will probably be repeating the experiment in controlled, professional, scientific environments,” said Horsevad. “One would therefore generally be advised to await the results of his experiments before basing any important decisions on the outcome of the girls’ experiment.”
It was going to be repeated, but I didn’t find the research. Professor Johanssen has some startling information about DNA damage from WiFi causing irreversible sterility in humanity in the next five generations, however.
