The human body is a complex of different complex systems and organs.
Subscribe to development efforts in the study of the human body was realized in the twentieth century, primarily due to the extremely rapid technological development. It became possible explanation of the essence of electrical phenomena in the muscles, heart, central nervous system and other organs. Thanks to modern electronic devices, it was possible to measure with great accuracy the phenomena that occur in living human organism.
This breakthrough scientific thought and understanding of the environment and the environment has opened a new chapter that is scientifically called BIO-electromagnetism (hereinafter referred to as BEM). BEM is an extraordinary science that mutual interaction with the electromagnetic field (hereafter EM).
Electric phenomenon is found in all living organisms.
The consequences of the impact of EM can be positive. Changes in the natural (internal) field of the body can cause physical and psychological changes.
To understand the effects of fields, first Morano know common ground that arise from changes in EM fields.
If the current DC – DC flows in one direction and the magnetic field is constant. If the alternating electrical current – AC, means the current changes direction, the electromagnetic field is also alternating-pulsed.
EM field has an electric and magnetic field. It is characteristic for its size, frequency and pulse – frequency (one change per second is a unit change in frequency = 1 Hz). Pulsed field is in its own way, theoretically extends to infinity in space by reducing the force with distance and eventually becomes lost in other EM fields that fill the space. Since the pulsed, the field also has a wave motion. The waves from the source at the speed of light (300,000 km / sec.). As a result, the wavelength, ie. the distance between the start of each wave, which is inversely proportional to frequency.
frequency of 1 Hz has a wavelength million kilometers, or 1MHz frequency has a wavelength of several hundred feet, and has a 100MHz frequency wavelength of about 1.83 m (6 feet).
All known frequencies are classified in the spectrum range of DC (zero frequency) to the highest frequencies, such as gamma rays and cosmic rays. The so-called. EM spectrum includes X-rays, microwaves, visible light, the frequency of the TV and radio, etc. What’s more, all EM fields are fields of energy capable of producing the effect of distance. These fields have characteristics of both a particle and wave. Depending on the direction of research can be found either waves or particles – photons.
The photon energy is immeasurable mass of particles. The higher the energy of the photon, the higher the frequency, which is directly related to its wavelength.
The human eye perceives only a part of the natural frequency of the EM spectrum as the light. The photon transmits the eye that converts it into electrical signals in the nervous system which is the product of sensitivity to light.
The classical parts of EM fields, depending on their frequency, are arranged from extremely low frequencies (ELF), low frequencies (LF), radio frequency (RF), microwave and radar (MW), infrared, visible light, ultraviolet, X-rays and γ-rays.
For oscillatory fields applies: the higher frequencies higher energies.
In the last five years have developed discussions on unhealthy influence of electromagnetic waves on human health, especially when mobile phones have become more and more present in everyday life.
Mobile phones are sources of high frequency. Their antenna and the transmitter and receiver high-frequency radiation (of approximately 2 GHz) and used immediately to the head. The problem with using mobile phones is that the impact of electromagnetic fields observed only after a long period of time. The result is (see column three), in addition to other organs, especially the eyes, excessive heat, which may interfere with the function of the body.
By setting the limits of maximum radiation, the industry is trying to reduce potential risks. It is not only important power output, but also the type, material and time use. In order to prevent potential health risks recommended great distance from the antenna. This is not possible with a mobile phone, which means that you are trying to avoid.
Since the EM field has electric and magnetic fields as well as electromagnetic radiation, it can be associated with the basic characteristics present in the following way:
|Low-frequency magnetic fields||Low-frequency electric fields||Electromagnetic waves|
|The magnetic field is generated only from the magnetic current (voltage is not important because they cause an eddy current)||Created exclusively from voltage (curent is not important), by changing the frequency changing current. The bodies do not absorb||To the extent treble frequency electric and magnetic fields are closely related. In the human body, creating a circular current. This radiant energy is absorbed and transformed into heat in the human body.|
The inner field (which is the product of living organism) different from the external field (which is a product of an external source outside the body). The external field can be natural, such as the Earth’s geomagnetic field or artificially created.
Electropollution term refers to the artificial EM field that can be risky to health, as we have seen with the use of mobile phones.
Although it has long been known that exposure to ionizing EM radiation really can cause huge damage to human tissue, recently new epidemiological studies and other evidence suggest that longer exposure to non-ionizing external EM field that produces lines of force, increasing health risks.
These hazards include danger and childhood leukemia (Bierbaum and Peters, 1991; Nair et al., 1989; Wilson et al., 1990a).
Also, it was found that ionizing oscillating EM field ELF range, can have strong biological effects, which can enhance the positive effects (Becker and Marino, 1982; Brighton and Pollack, 1991).
This discovery is the cornerstone of the establishment and application of science BEM – a.
