What is radiation? How did radiation produce?
TV tower, telecommunications microwave tower, mobile phones, microwave ovens, motors, motors and so have radiation, electromagnetic field generated
Broadly speaking: where the energy is not through the conduction or convection, but directly through the space to convey it to the way collectively referred to as radiation.
In the narrow sense: radiation can be divided into: 1. High-energy free radiation (known as radiation) such as X-ray, alpha (abaca) ray, beta (beta) ray, γ (gamma horse) ray, this is the so-called radiation The 2. Low-energy free radiation (commonly known as electromagnetic waves) such as microwave ovens, mobile phones, radio stations, substations, kinescopes, etc. issued by the electromagnetic waves. Free radiation can cause large or biological lesions or death.
Lower energy of free radiation, that is, electromagnetic radiation. According to the different vibration frequency can be divided into microwave, very high frequency, UHF, FM, low frequency, very low frequency and other areas. Its impact on human physiology has been published in many reports, especially electromagnetic radiation (MAGNETIC RADIATION referred to as EMR), has become the latest threat to modern human disease. In the place where there is current through, high-voltage lines, radio stations, radar stations and so on are very high radiation, according to foreign research reports that: breakthrough (pulsating wave) and uneven electric welding will produce a sudden wave (pulsating wave) And uneven electromagnetic radiation, which is why the female computer operator's pregnancy abortion accident and welding work function abnormal proportion of the reasons for the market.
Radiation refers to the energy in the form of electromagnetic waves or particles (such as alpha particles, beta particles, etc.) in the form of outward diffusion. Everything in nature, as long as the temperature above the absolute temperature of zero, are in the form of electromagnetic waves and particles non-stop outward radiation.
Common radiation has electromagnetic radiation, solar radiation, heat radiation, chemical radiation and so on.
