Low-frequency vibrations are produced by organs of the human body. The brain has a resonance frequency of 10 hz, and the heart about 1-1.67 hz. Over exposure to high frequency radiation leads to damage of the body. For example, microwaves are forms of electromagnetic
radiation with typical frequency of 300 hz to 3000 hz, which cause
internal heating of body tissues. Infrared frequency of 3000 hz to
30,000 hz cause skin to burn. X-rays frequency of 3 x10^16 hz to 3
x10^17 hz cause mutations which may lead to cancer and cell death - this
is why doctors and dentists stand behind protective screens when taking
X-rays.
Mobile phones and TVs use radio waves frequencies of less than 3 x10^9. When using mobile
phones, various factors should be considered, such as the duration,
location, and method of use, in order to reduce the possible effects of
exposure to radiation. Prolonged exposure to mobile phone lead to
increased body temperature, reduced sperm counts and male infertility.
For that reason, the mobile phone should be away from the waist.
Evidence exists for an association between neuro-developmental or
behavioral disorders in children and exposure to wireless devices.
Experimental evidence shows that prenatal exposure could cause
structural and functional changes in the brain associated with ADHD-like
behavior.
