Scientists and public health officials assess risks to human health based on the entire body of evidence, rather than individual scientific studies. The evidence is considered by panels of experts in this field. We look to such expert reviews for advice on mobile devices, masts and health. We only consider the opinion of panels commissioned by recognised national or international health agencies, for example, the World Health Organization (WHO), The Health Council of the Netherlands (HCN), The Swedish Radiation Safety Authority (SSM) (formerly the Swedish Radiation Protection Authority - SSI) and The UK Health Protection Agency (HPA).

Since 2001, there have been a significant number of expert reviews of scientific research studies into mobiles, masts and health published by expert panels around the world. This page contains a summary of reviews published from 2006 to date. See the table of expert reviews for a complete list of reviews meeting our standards of scientific rigour.

In May 2011, an expert group from the International Agency for Research on Cancer (IARC), a specialist agency within the World Health Organization (WHO), announced its cancer hazard assessment for radiofrequency signals (RF), including those from broadcast, mobile communications, microwaves and radar.


IARC classified RF as “possibly carcinogenic to humans (Group 2B), based on an increased risk for glioma, a malignant type of brain cancer, associated with wireless phone use.” The full findings of the group’s work were published on 19th April 2013, in IARC Monograph 102, and confirmed the 2B classification from May 2011.

The WHO will produce an RF health risk assessment based on a review of the scientific evidence for all potential health effects of exposure to RF fields, which will be informed by the IARC classification and is anticipated in 2015/16.

The International Commission on Non-Ionizing Radiation Protection (ICNIRP), a non-governmental organisation formally recognised by the World Health Organization, provides guidance on limiting human exposure to RF fields. See their 1998 guidelines which, in August 2009, the ICNIRP confirmed were still valid.
