In December 2013 a statement by the Nordic Radiation Safety Authorities was published on expoure from mobile phones base stations and wireless networks.  The statement says:

"The overall data published in the scientific literature to date do not show adverse health effects from exposure of radiofrequency electromagnetic fields below the guidelines or limits adopted in the Nordic countries. However, epidemiological studies on long-term exposure to radio waves from mobile phones are still limited, especially studies on children and adolescents.

There are several ways to reduce exposure from mobile phones. This can for example be done by using a hands-free device or the mobile phone loudspeaker function while communicating. The exposure can also be reduced if the mobile phone is primarily used in areas with good coverage. Text messaging results in a very low level of exposure.

Since exposure of the general public, including children, to radio waves from the wireless local area networks and base stations is far below the exposure limits, there is no need to further limit exposure from these radio wave sources.

There will be some decades before studies of the association between lifelong use of mobile phones and chronic health problems will be available. Given the large number of mobile phone users, it is of great importance to monitor any potential impact on public health. This is why the Nordic radiation safety authorities are continuing to closely monitor research conducted on mobile phone use and any potential health risks."
