There is a growing number of scientists looking at Wifi Health Risks Research and the causes of Electromagnetic Sensitivity and Electromagnetic Hypersensitivity.
In the UK one of the best summaries of the ongoing research efforts is the work of Michael Bevington.
Over 1,800 research references are contained in Bevington’s 2013 book “Electromagnetic Sensitivity and Electromagnetic Hypersensitivity: A Summary”

These are invaluable sets of abstracts (data-based to be searchable) covering the Radio Frequency Radiation scientific literature, as well as collections of scientific abstracts on free radical damage and a set specific to electrosensitivity. They cover the research published between 1990-2014
The Wifi health risks research is at a point where the main stream media can no longer ignore their findings.
