Electromagnetic Radiation

The electromagnetic radiation, is also called electronic smog by space together the electrical energy transfer and magnetic energy composed, and the energy is generated by charge mobile, For example, are transmits the rf antenna issued by moving charge, will produce electromagnetic energy. The electromagnetic spectrum "includes" all kinds of electromagnetic radiation from extremely low frequency electromagnetic radiation of extremely high frequency electromagnetic radiation. Between and radio waves, microwave, and infrared, visible and ultraviolet light, etc. The electromagnetic spectrum rf part of the general definition, it is to point to frequency about from 3 KHZ to 300 JiHe radiation.

The electromagnetic radiation the harm to human body

The electromagnetic radiation is a composite electromagnetic wave to perpendicular electric field and magnetic field changes over time and energy. Human life activities include a series of bioelectricity activities, these bioelectricity of environment of electromagnetic waves are very sensitive, therefore, the electromagnetic radiation can cause damage to human influence and.

GaoErSheng professor in his "air conditioning usage of semen quality" the influence of electromagnetic radiation, noted that the harm to human body, performance for heating and non-thermal effect two aspects.

thermal-effect

When human body accept electromagnetic radiation, the body with electromagnetic field of molecular conversion fast motion, make human body temperature, heating causes central nervous and plants spirit system function obstacle, main show is dizzy, insomnia, forgetfulness and other sub-health performance.

Non-thermal effect

Namely absorbed radiation enough to cause temperature increase, but also cause physiological changes and reaction. Living and working in this kind of environment is too long, can appear giddy, exhaustion, memory loss, anorexia, etc clinical symptoms.

The 1998 world health organization in the latest survey

Electromagnetic radiation on human had five influence

1 and electromagnetic radiation are cardiovascular disease, diabetes, cancer mutations in the main inducement,

2, the electromagnetic radiation on human reproductive system, nervous system and immune system caused by direct damage,

3 and electromagnetic radiation is caused to miscarry, infertility, such lesions excessively tire causative factor,

4, excess electromagnetic radiation directly affect children's organizational development, skeletal growth, declining eyesight, Liver hematopoiesis function decline, serious can lead to the retina fall off.

5 and electromagnetic radiation can make the male sexual decline, female endocrine disorder, menstrual disorders.
