Book excerpt: This volume of the IARC Monographs provides an evaluation of the carcinogenic hazards associated with exposure to electromagnetic radiation in the radiofrequency range (30 kHz to 300 GHz). Human exposures to radiofrequency electromagnetic fields can occur from use of personal devices (e.g. mobile telephones, cordless phones, Bluetooth, and amateur radios), from occupational sources (e.g. high-frequency dielectric and induction heaters, high-powered pulsed radars), and from environmental sources (e.g. mobile-phone base stations, broadcast antennae, and medical applications). The general population receives the highest exposure from transmitters close to the body, including hand-held devices such as mobile telephones. Typical exposures to the brain from mobile-phone base stations and from television and radio stations are several orders of magnitude lower than those from second-generation GSM handsets, while 3G phones emit, on average, about 100 times less radiofrequency energy than GSM phones. Similarly, the average output power of Bluetooth wireless hands-free kits is estimated to be around 100 times less than that of mobile phones. An IARC Monographs Working Group reviewed epidemiological evidence, cancer bioassays, and mechanistic and other relevant data to reach conclusions as to the carcinogenic hazard to humans from exposure to these electromagnetic fields. With "limited evidence" for carcinogenicity in humans based on an increased risk of glioma - a malignant brain tumour - among heavy users of mobile telephones, radiofrequency electromagnetic fields were classified as "possibly carcinogenic to humans" (Group 2B).
