There’s disagreement in scientific literature over whether EMFs pose a danger to human health and, if so, how much.
The International Agency for Research on Cancer (IARC) has classified non-ionizing EMFs in the radiofrequency range as Group 2B, a possible human carcinogen. These fields are produced by electronic products like cellphones, smart devices, and tablets.
IARC operates under the World Health Organization (WHO). It convenes working groups of scientists from around the world regularly to evaluate the cancer risks presented to humans by environmental and lifestyle factors.
The current IARC evaluation from 2011 pointed to a possible link between RF radiation and cancer in people, particularly glioma, a malignant type of brain cancer.
