I have found out a lot of information about this subject.
Some studies have shown mobile phone radiation does produce biological changes in humans – such as changes in brain temperature and activity as well as blood pressure changes. Others have shown they cause an increased incidence of illness in laboratory animals – for example cancer in mice.
Last December, a consortium of 12 research groups in seven European countries announced it had found evidence mobile phone radiation can damage DNA in human cells in the laboratory – changes that weren’t repaired by the cells and remained when they divided.
Many scientists dismiss these findings as inconsistent and unreliable. Millions of people who use mobile phones don't seem to be harmed by them, they point out.
Some articles that I have seen don't conclude that the use of mobile phones can cause significant health problems. However, many aspects of mobile phones radiation still remain to investigate.
Particularly, I believeit that a continued and exahustive use of mobile phone is not good.
