IARC classification for radio frequency fields (RF)

On 31st May 2011, IARC classified radiofrequency electromagnetic fields 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.
IARC state in the summary of results:

“The evidence was reviewed critically, and overall evaluated as being limited among users of wireless telephones for glioma and acoustic neuroma, and inadequate to draw conclusions for other types of cancers. The evidence from the occupational and environmental exposures mentioned above was similarly judged inadequate”

IARC has published a news article (Carcinogentity of radiofrequency electromagnetic fields) providing further details of the classification in the Journal - Lancet Oncology (online 22nd June 2011).

The IARC assessments for RF will be published as Volume 102 of the IARC Monographs in 2012.
