The discussion on the biological effect of mobile phone radiation

At present mobile phone radiation is proved to have two main effects which are respectively thermal effect and nonthermal effect (also called biological effect). For a long time, the problems of thermal effect brought by mobile phone radiation are researched more in respect that thermal effect is more obvious and its affect has been recognized in the world. However, there are bifurcation and controversy about non-thermal effect which is being studied and has no determinate conclusion.
