Frequency and resonance effects links

At frequencies near the body’s natural resonant frequency, RF energy is absorbed more efficiently, and maximum heating occurs. In adults, this frequency usually is about 35 MHz if the person is grounded, and about 70 MHz if the person’s body is insulated from the ground. [Note: TETRA base stations have a signature at 70.64 Hz.] Also, body parts may be resonant; the adult head, for example is resonant around 400 MHz [note: TETRA operates at 380 to 390 MHz], while a baby’s smaller head resonates near 700 MHz. Body size thus determines the frequency at which most RF energy is absorbed. As the frequency is increased above resonance, less RF heating generally occurs. However, additional longitudinal resonances occur at about 1 GHz [note: GSM operates at 900 MHz and 1200 MHz] near the body surface. [source, but attested widely.]

We are also tuned to the extremely low frequencies of the planet, around 8 to 12 Hz (Schumann resonance), and brain frequencies (which resonante throughout the body not just the brain) track these. The whole point is that the body is not shiny and reflective to microwaves like it is to light. Below light frequencies we are absorbent. But it isn’t just a case of taking up raw energy and getting hot, it is about ‘ringing’ in resonance to signals at frequencies that matter to the way our bodies function. And for those who say there is no way frequencies can mean anything, much of the human body is not just conductive but semi-conductive.

So can microwave radar – and it’s nothing to do with ears! If mind control is a step too far, just remember that this is a factual military step, so concentrate on whether the effect can be achieved and how.
