Mobile. -A huge biological experiment
Beware if you are sitting with mobile phone glued to your ear most of the day. Even tiny doses of radiation can damage the brain, research shows.

Interphone
International study on the use of mobile phones can cause brain cancer or other damage.
13 countries participating: Australia, Canada, Denmark, Finland, France, Germany, Israel, Italy, Japan, New Zealand, Norway, Sweden, United Kingdom.
Coordinated by WHO's International Agency for Cancer Research, IARC.
13 delrapporter conclude that mobile use does not give an increased risk of brain cancer.
"We are witnessing a giant biological experiment, where people voluntarily set up as laboratory animals. Three-quarters of Earth's population use mobile phones. They take words, this little widget that sends out a mass-rays, and press the voluntary to the head. It is the largest human-controlled biological experiment ever.
Kraft ointment comes from the Swedish professor and brain surgeon Leif Salford at the University Hospital in Lund. His research shows that even tiny doses of microwave rays damages cells in the brain.
Since 1988, Salford and his colleagues exposed laboratory otter for mobile radiation, and they found that the radiation is causing leakage through the so-called blood-brain barrier. Blood vessels in the brain is closer than the walls of blood vessels elsewhere in the body, and this blood-brain barrier is a protection against viruses and other harmful substances from penetrating the brain. The researchers in Lund could prove that the albumin had penetrated the brain of rats. Albumin is a protein found in blood, but normally do not need the blood-brain barrier. And albumin in brain tissue is a sign that the brain, at least for a while, has lost some of its protection.
Low doses
The experiments in Lund showed that just 15 minutes' exposure to a normal mobile phone could cause albuminlekkasje to the brain. Plus: One single two-hour irradiation was NOK to open the blood-brain barrier in up to 14 days. Autopsies after 28 days and 50 days showed that up to 2prosent of rats brain cells were damaged in the areas of the brain which are concerned with learning, memory and movement to do.
But the most sensational of the studies in Lund's results show that the lower the radiation effect is, the greater the albuminlekkasjen. Limits for exposure to the head is 2Watt pr.kilo. Professor Salford research has shown that the harmful effects on brain cells occurs at the low irradiation as 0.00004 Watts pr.kilo.
-It appears that proteins and perhaps toxins can go from the blood and the brain when the mobile phone is active. And this effect is stronger the lower the radiation is. In our experiment, there were fewer than 50prosent of rats that received such albuminlekkasje. Why this happens, we do not know. But in 22 years, we have shown - with rats - and nothing happens in the brain, says Professor Salford.
It is not safe to use mobile phone. There are a number of biological effects of this radiation, including the risk of brain tumor is only one.
-How likely is it that the same effect will occur in the human brain?
-Until recently we thought that men and rats blod-/hjernebarrière were identical. Now it turns out that there is a tiny difference, but I do not think the difference is particularly significant. It is therefore more likely that the same happens in the human brain than that it does not happen. It may that man is able to repair this - we do not. But we have proven that there's stuff: Albumin enters the brain and nerve cells are damaged or die.
-How severe is the damage of albumin in the brain?
-If the brain is exposed to albumin - let's say you are from 5-10 years old and over several decades-that the brain probably spend a lot of energy over many years to get rid of this albumin. The reader will probably overstrain the brain and use up spare capacity and may develop dementia, Alzheimer's and other diseases, as one does not wish to incur the too young age. This is a risk, "said Salford, who recommends people to use mobile phones as little as possible.
-Keep your old phone to plug in the wall. Use your mobile as much as you can and then only with hands. Turn off your mobile and put it away from you. Do not leave it lying beside the bed. Children and young people should not use mobile. The passive radiation we are exposed to - from base stations and other people's mobile phones - also affects. We now have a generation who pumps himself full of energy in all directions, and you have to carry around as a possible scenario that the mobile use can have consequences.
-If there is such that even small radiation doses damage the brain, why does not the government react?
-This is a very sensitive question. Authorities, the mobile industry and the WHO are perhaps afraid to make humanity uneasy. They would probably like to say that this is a modest research and trivialize the whole thing.
-My strong encouragement of governments, organizations and mobile industry is that they bet big, actual amount in order to find other carriers, which do not have the same negative effect on the brain and biology, "said Salford.
Interphone
He calls the results from the major international mobile Interphone study, which started ten years ago. 13 countries, including Norway, participate in the survey, which will look at possible risks of mobile use. Despite the latest data were collected six years ago, is the final report is still not made public.
Leif Salford colleague at Örebro University Hospital, Professor Lennart Hardell, is also highly critical of the Interphone investigation is not made public. Hardells research shows a significant increased risk of brain tumor by the use of mobile or cordless phone for ten years or more:
* 100 hours in mobile phone increases the risk of brain cancer with 5prosent.
* For each year using the mobile, the risk of brain cancer with 8prosent.
* After a decade or more with mobile use, the risk increased with 280prosent.
* Those who were teenagers or younger when they started using their mobile phones, will increase the risk of brain cancer with 420prosent.
-The rumors in the community say that the Interphone investigation confirms our findings and that researchers can not agree on the interpretation of results. Whatever it is irresponsible not to publish the results and allow others to take part in them, "said Professor Hardell.
-It is not safe to use mobile phone. There are a number of biological effects of this radiation, including the risk of brain tumor is only one, "said Hardell.
Criticism
Interphone survey is coordinated by the World Health Organization (WHO), and it is funded by the European Union, the International Cancer Research and the mobile industry itself. To date, the Interphone only published individual studies, where no one has concluded with any increased risk of brain tumor, but that one can not rule out an increased risk by more than ten years of mobile use. Interphone investigation has been criticized for the method used, biased selection of respondents and the composition of control groups.
Researcher Lars Klæboe at NRPA's behind the Norwegian delstudien, which shows that mobile phones do not give increased risk of brain cancer. Also, his research is funded by the mobile industry.
-Half of the money came from the EU, the rest from an umbrella group of mobile manufacturers. For me it's not important where the money came from, and it was over my head no guidance from the industry. I agree with some of the criticism that has been submitted to Interphones method use. When there are weaknesses in the methodology, it will have an impact on the results credibility. -Why is Interphone still not published?
"We have agreed not to comment on some things before the report comes out. There is an explanation of why this has taken some time, but I can not come even before the results are, "says Klæboe.
