Dariusz Leszczynski holds 2 doctorates and docentship in biochemistry. He worked for 22 yrs at STUK – Radiation and Nuclear Safety Authority in Finland and in 2011 was one of the 31 scientists in the IARC/WHO Working Group for classification of the carcinogenicity of cell phone radiation.
In a recent lecture he discussed some of the game-changing studies since 2011 which strengthen the evidence to move the carcongenity of EMR radiation on the IARC scale from possible (2B) to probable (2A).
In the meantime his conclusion includes practical recommendations like keeping cellphones out of pockets and avoiding the deployment of Wi-Fi in schools with preference being given to wired internet connections.
And why children are more at risk than adults.
Here is his slideshow presentation: https://betweenrockandhardplace.files.wordpress.com/2016/02/iceland-27-01-2016.pdf
