Action from the World Health Organisation and IARC:
On 31st May 2011, the World Health Organisation (WHO) and the International Agency for Research on Cancer (IARC) classified radiofrequency (RF) radiation as Group 2b ‘Possibly carcinogenic to humans’ and extremely low frequency ELF radiation was previously classified in the same group.

WHO-classificationNo other environmental carcinogen has produced evidence of an increased risk in just one decade 2. Other agents in this classification include lead, DDT, diesel fumes and chloroform.

Accompanying this warning from WHO are warnings from medical doctors groups 3 4 5 6 7 8 9 10 11 12 13 14 15 16, scientific panels 17 18 19 20 21 22 23 24 25 26 27 28, teaching unions 29 30 31 32 33 34, parliamentary assemblies 35 36 and other governments globally 37 38 39 40 41 42 43 44 45 46. Many of those on the IARC panel and other scientists have since publicly voiced their belief that the category should have been Group 2A ‘Probably carcinogenic to humans’ 47 48 49 50 51, or Group 1 ‘Carcinogenic to humans’ 52 53 54.

This is justified in part, by the fact that acoustic neuroma and glioma (a rapidly progressive fatal brain cancer) satisfy the Hill criteria for causality from radiofrequency (RF) exposure 55. Disturbingly, brain tumours have now overtaken leukaemia as the leading cause of cancer death in children and both of these cancers have been associated with EMR exposures in peer-reviewed, scientific publications.

The comet assay featured below demonstrates DNA fragmentation from non-thermal exposure levels of EMR generated from real devices. The length and density of the comet like tail emanating from the DNA allows a quantitative assessment of damage.

Note: this 2b classification applies to all RF frequencies, and is therefore relevant to all devices.
