The risk of electromagnetic radiation coming from mobile phones, both the devices as the masts, is still unclear. On the one hand, there does not exist an article that unambiguously proves any health risks. But there is not yet a research about all the effects – in particular, because there has not been enough epidemiological research about prolonged exposure to low doses.  An overview of SAR-values  displays how much electromagnetic radiation penetrates the body per mobile phone. There is no unambiguously evidence that high SAR-values are harmful for the health and/or a lower SAR-value are less harmful for the health.
According to the epidemiologist and publicist Devra Davis the mobile phone-industry features a fund of 250 million dollar to respond adequately to the industry’s negative research results (wargaming the science).
