In a 21st Century world, we are increasingly surrounded by WI-FI, yet there is no clear scientific consensus about its effects on us. However, an experiment has shown that these invisible signals generated from cellphones and laptops could be causing serious damage to plants.
Five ninth-grade young girls from Denmark created a
science experiment that caused a stir in the scientific community.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 top honors in a
regional science competition and the interest of scientists around the
world.
But there is some debate over whether the negative effects were due to the cress seeds drying from the heat emitted by the computer WI-FI routers used in the experiment. The study would raise fears that WI-FI radiation may also be having effect on the human body and will lend weight to parents and teachers who have campaigned to stop wireless routers being installed in schools.
