**5. Conclusion**

From the more than 30 expert group opinions that were published during the 2009-2011 period the vast majority did not consider that there is a demonstrated health risk from RFexposure from mobile telephones and other wireless communication devices. Because of remaining uncertainties, especially with respect to long-term exposures, some caution is still expressed. This is the reason why IARC recently classified RF-electromagnetic fields as 2Bcarcinogens (= possibly carcinogenic).
