WoD – Screaming WiFi

This is both fascinating, and highly disturbing at the same time.  (But then it wouldn’t be a WoD if it wasn’t, right?)

I have wondered often about this issue.  Every time I see a cabbie or a silly, showy salesperson with a bluetooth wedged in their ears ALL DAY LONG (yes, bluetooth is a radio, emitting radi-ation right next to one’s brain), it makes me think of the potential radiation damage.  I am glad to finally see I am not the only one.  What’s amazing is, it took 9th grade girls to show it so starkly (just look at the two pictures below).

So, as you sit with your super-powered cellphones in your pockets (egads!), tablets on next to our beds, with laptops on laps, 2 routers in the house, and with probably about 12 devices all zipping data to and from, all day long, now think of this below.  I’m feeling a bit more shriveled and cancer-prone just writing this…

 

Student science experiment finds plants won’t grow near Wi-Fi router

Ninth-graders design science experiment to test the effect of cellphone radiation on plants. The results may surprise you.

Cress Collage-1Five ninth-grade young women from Denmark recently created a science experiment that is causing 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 (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.
