Nonthermal Mechanism of Low-Level Microwave Effect on the Human Brain

This book presents a systematic description of the physical mechanisms and properties of low-level microwave radiation effects. It introduces the concept of nonthermal mechanism of microwave radiation effects, with special reference to the nonlinearity of neurophysiological and biological processes. With insights into electromagnetism, bioelectromagnetism, and nonlinear dynamics, this comprehensive volume proposes new ideas for updating the health protection limits for radiofrequency radiation and recommends following the precautionary principle to minimize health risks. Features: - Explains how cumulative minor disturbances from coherent microwave radiation overcome thermal noise limits, enabling low-level microwave impact on biological processes. - Confirms that dielectric polarization triggers small initial changes that produce significant alterations in nonlinear living systems, causing nonthermal effects. - Demonstrates that predominantly positive results across multiple tissues and cells from numerous independent studies support the capability of low-level radiation to cause biological effect. - Shows why modulation frequency is crucial in microwave effects, with the impact directly dependent on modulation frequency. - Concludes how brain effects vary between individuals, with only a minority experiencing significant impact. - Emphasizes that the body's repair mechanisms prevent biological effects from becoming health effects, due to nonlinear chaotic nature of the processes with unpredictable outcomes. This book is aimed at graduate students, researchers, specialists, and academics in biomedical engineering, physics, medicine, medical physics, microwave engineering, health protection, biophysics and biochemistry.

Hiie Hinrikus was born in the Republic of Estonia in 1934. She received her primary and secondary education in Tallinn, Estonia. Afterwards, she was educated in Physics, with a specialty in Radiophysics, at the Lomonosov Moscow State University. Her diploma work at the Sector of Radio Astronomy of the Lebedev Physical Institute of the Academy of Sciences of the USSR was related to the sensitivity of microwave radiometers. She completed her doctoral studies, investigating noise in masers at the USSR National Institute of Physical-Technical and Radio-Technical Measurements in the Moscow Region and received a PhD in Radiophysics.
