How Long Is Too Long to Talk on My Cellphone?
Research from leading brain imaging researchers from the National Institute of Health, revealed that just after 50 minutes of cell phone exposure, the emitted radiation increases brain cell activity in the region closest to the cell phone antenna. The exact health effects of that increased brain activity are as of yet unknown, but the study effectively debunked the U.S. government research circles that cell phone radiation at non-thermal levels is incapable of causing biological change.
Safety guidelines for microwave radiation emitting devices are based on the Specific Absorption Rate, known as the SAR value. The SAR value is a measure of the energy emitted by the cell phone and its potential for heating tissues – but the SAR only is a gauge the thermal impact of cellphone usage. As the mentioned research found, it is very likely that non-thermal effects of chronic cellphone exposure are even more biologically damaging.
A cellphone is a two way microwave device whose long term use has been associated with not only brain tumors but with 7 different cancers in all. They include glioma, acoustic neuroma, meningioma, salivary gland tumors, eye cancer, testicular cancer and leukemia, along with a wide range of other biological effects.
Around the world, many countries are already adopting the Precautionary Principle. Canadians are being encouraged to limit cellphone call length and to text message or use a hands free device whenever possible. Russian officials have issued the recommendation that all children under the age of 18 should avoid using cell phones entirely. The UK, Israel, Belgium, Germany, India, France and Finland also urge citizens to err on the side of caution with respect to their children’s use of cellphones.
In the United States warnings are not yet commonplace, but it’s still important to protect yourself.
