Habitual, long-term mobile phone users could soon know if they are at risk of developing cancer.
In what is believed to be a world-first study, human brain cells are being used to test the long-term effects of mobile phone radiation.
The study will use a device to simulate (模拟) the effect of longtime exposure(暴露) of the brain to electromagnetic radiation from mobile over a long period.
Testing will be done by researchers at Sydney's St. Vincent's Hospital . The project's chief investigator(调查者) , Peter, a French researcher, said the trial would test whether mobile phone radiation causes cancer in long-term users.
Testing will either prove people's fear, or show that there is no effect on human brain cells or perhaps that cells can become immune(免疫的) to electromagnetic radiation through repeated exposure.
During the study, brain cells will be exposed to electromagnetic radiation for an hour each day. Test results are expected in three to six months, with the final report to be published by the end of the year.
The research is unique because most previous studies have focused on short-term exposure on animal cells, which did help understand the effects of years of regular mobile phone use on human brain cells.
As mobile phones become increasingly popular throughout our society, it is important that we understand as much as possible about the long-term effect of electromagnetic exposure, if any, on human health.
