Radiation Electromagnetic Fields And Cancer

Radiation Electromagnetic Fields

Electromagnetic fields and health
Are becoming more electronic devices and technological advances that provide us modern civilization: mobile phones, computers , microwave ovens,televisions, etc.


All this has been a really dramatic change in the civilized man life in a few years. But again we are faced with a number of human achievements that isolate us from nature and the enjoy of the simple things in life.


Apart from the possible negative psychological effect that represent for us, these advances can often present an additional risk :we are talking about electromagnetic radiation.


Radiation is any energy emission that spread through the air or in vacuum.

These rays consist of small packets of energy called photons that propagate describing sine waves, which is why we can speak of electromagnetic waves.

The two main characteristics of these radiations are the vibrational frequency and intensity. The frequency describes the number of cycles per second that trace the photons, and is measured in hertz ( Hz).

Thus 1 Hz is one cycle per second . A kilohertz (kHz ) is 1,000 cycles per second, one megahertz (MHz ) , one million cycles per second , and one gigahertz (GHz ) , one billion cycles per second. The electromagnetic radiation intensity is the amount or density of emitted waves.


The higher is the oscillation frequency of the electromagnetic wave, the greater is the energy of each photon. The biological effects of radiation or electromagnetic field will then be greater the higher is the intensity and the higher is the frequency. Flow fields are called electromagnetic waves electromagnetic (EMF ) ore lectromagnetic radiation (EMR ).


Effects of electromagnetic waves
The following table summarizes the different types of electromagnetic waves existing and potential biological effects:





Static electromagnetic fields
Characterized by the absence of vibrational frequency, ie , are constant , without oscillation . Static electric fields do not penetrate the body, and seem to have no effect on health.

Static magnetic fields penetrate the body without losing intensity. Very high intensities of this field type have some circulatory and nervous effects, but these intensities are not in everyday life.
