Professor Yury Grigoriev was one of the greatest scientists ever and remained humble, kind and was full of integrity. He fought hard to alert the world about the risks associated with wireless technology and was especially concerned for the health and well-being of our children.

Here is a list of his credentials:
Professor Yuri G. Grigoriev (PhD, DMedSci) 1925-2021
‘Chief Scientific Officer, Laboratory of Radiobiology and Hygiene of Non-Ionizing Radiation, Burnasyan Federal Medical Biophysical Center of the Federal Medical Biological Agency (Russia); Academician, Academy of Electro-Technical Sciences (Russia); Deputy Chair, Bureau of Radiobiology, Russian Academy of Sciences; member of the WHO Advisory Committee (International EMF Project); Member of the Russian Scientific Commission on Radiation Protection; Member of the Russian National Committee on Non-Ionizing Radiation Protection; Member of the International Commission for Electromagnetic Safety.’
Radiation Research Trust Director Eileen OConnor directly asked Professor Yury Grigoriev a question with respect to comparing the severity of non-ionizing radiation compared to ionizing radiation. He said, “Ionizing radiation is monitored with safety systems in place to contain and control and prevent overexposure. The current proliferation of wireless frequencies is worse as levels of non-ionizing radiation are constantly increasing and ubiquitous; it is out of control. The world-wide dissemination of mobile telecommunications has resulted in new sources of large-scale population exposure to radio-frequency electromagnetic fields. Prevention of childhood and juvenile diseases from exposure to EMF sources is of paramount social and economic importance. It is one of the bases for public health policy in the near and long-term future. The human brain and the nervous system tissues directly perceive EMF and react irrespective of its intensity, and in certain cases it depends on EMF modulation. This feature distinguishes EMF from all other environmental factors and complicates human health risk assessment for EMF exposure. A situation has emerged that cumulative EMF exposure of children may be comparable to adult exposure and may be equal to the levels of occupational exposure of workers. The current standards are outdated and inadequate. Urgent action is needed to curb the negative impact from this physical agent.”
Professor Yury Grigoriev also famously said:
“Man conquered the Black Plague, but he has created new problems – EMF Pollution.”
