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.

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!
New research highlights the risk of ionising radiation from computed tomography (CT) scans given to children. Radiation exposure from 2 to 3 CT scans of the head in childhood (aged under 15 years)—giving a cumulative dose of around 60 mGy—could increase the risk of developing brain cancer; around 5 to 10 scans (cumulative dose around 50 mGy) could increase the risk of leukaemia. While the absolute risk of these cancers occurring after CT scanning is small, radiation doses from CT scans should be kept as low as possible and alternative procedures, that do not use ionising radiation, should be considered.

Cancer Risk Assessment Needed? Sampling the Pacific for Signs of Fukushima : Woods Hole Oceanographic Institution
Keep in mind that radiation is the cause of free radicals that damage genetic materials and cells, cancer kill more people than all war. According to the WHO “In the year 2000, malignant tumours were responsible for 12 per cent of the nearly 56 million deaths worldwide from all causes. In many countries, more than a quarter of deaths are attributable to cancer.”

An international research team is reporting the results of a research cruise they organized to study the amount, spread, and impacts of radiation released into the ocean from the tsunami-crippled reactors in Fukushima, Japan. The group of 17 researchers and technicians from eight institutions spent 15 days at sea in June 2011 studying ocean currents, and sampling water and marine organisms up to the edge of the exclusion zone around the reactors.
“What this means for the marine environment of the Northwest Pacific over the long term is something that we need to keep our eyes on,” said Buesseler.

The Woods Hole Oceanographic Institution is a private, non-profit organization on Cape Cod, Mass., dedicated to marine research, engineering, and higher education. Established in 1930 on a recommendation from the National Academy of Sciences, its primary mission is to understand the oceans and their interaction with the Earth as a whole, and to communicate a basic understanding of the oceans’ role in the changing global environment.

The Office of National Statistics in the United Kingdom discovered a 50 percent increase in frontal and temporal lobe tumors in children during the ten year span covering 1999 to 2009. Was this a result of cell phone radiation? The Department of Health in the UK would…
EPA’s nationwide radiation monitoring system, RadNet, consists of two components. First, stationary and deployable air monitors measure radiation 24 hours a day, 7 days a week. The map provides monitoring results as graphs that are updated several times daily. You can also search the RadNet database in EPA’s Central Data Exchange (CDX) to find monitoring data. Second, EPA samples precipitation, drinking water, and milk on a routine schedule and tests them for radiation in a laboratory. The latest RadNet sampling results are available in Envirofacts.
