Description
Technical field
The present invention relates to a kind of electromagnetic radiation monitoring instrument, particularly a kind of individual electromagnetic radiation exposure monitoring alarm instrument.
Background technology
21st century is the epoch of electronic information, along with the fast development of hyundai electronics industry, telecommunication industry and popularizing of electric equipment products, electromagnetic energy density in the environment for human survival constantly strengthens, consequent harm is also day by day serious, become the another new environomental pollution source after water pollution, air pollution, noise pollution, its harmfulness is mainly manifested in following two aspects: the electromagnetic radiation pollution meeting threatens human health on the one hand, and electromagnetic wave can disturb the normal operation of electronic equipment on the other hand.
As everyone knows, human existence and life be unable to do without certain electromagnetic environment, are magnets such as the earth itself, and sunshine also is a kind of electromagnetic radiation, if but when electromagnetic radiation on every side surpasses certain threshold value, will form threat or the damage that works the mischief to human body.The mechanism of hazards of electromagnetic radiation human body mainly is thermal effect, non-thermal effect and cumulative effect etc.
Thermal effect:: namely electromagnetic wave can make some cell or tissue heating of human body.We know that human body is water more than 70%, and hydrone is under the effect of electromagenetic wave radiation, and molecule generation orientation effect in the human body rearranges, because the mutual collision friction in the intramolecular rearrangement process, have consumed electromagnetic energy and change into heat energy.The electromagnetic oscillation frequency is higher, and electromagnetic radiation energy is larger, and the orientation effect of molecule is strong with regard to Shaoxing opera in the body, and heat effect is also just more outstanding, and the damage of generation will be more serious.Will make human body heating and the high temperature physiological reaction normal operation of organ in the human body (or affect) occurs when the electromagnetic wave energy that is absorbed by the body acquires a certain degree, the pathologies such as neurasthenia, leucocyte minimizing will appear in human body.
Non-thermal effect: human body temperature can not raise, but can cause certain physiological reaction.All there is faint electromagnetic field in the Organ and tissue of human body, they are stable and orderly, in case be subject to the interference of external electromagnetic field, such as the electromagnetic wavelength time effect that surpasses some strength, the faint electromagnetic field that is in equilibrium state is about to be destroyed, and causes the resonance of human body cell film, makes the mobility of cell limited, this effect that occurs in the level of molecule and cell one-level is complexity but also meticulous not only, and the people is occurred such as the change of heart rate, blood pressure and insomnia, the physiological reaction such as forgetful.
Cumulative effect: after thermal effect and non-thermal effect act on human body, to the injury of human body not yet be able to do in time (usually said human body holding capacity---interior drag) before the self-regeneration, again be subject to the words of electromagenetic wave radiation, its extent of injury will be accumulated, of a specified duration can become permanent morbid state, threat to life.For the colony of Long Term Contact electromagenetic wave radiation, even power is very little, frequency is very low, also may bring out unimaginable pathology, should cause vigilant.
Electromagnetic radiation has certain impact to the health of human body, as be losing one's memory, the symptom such as insomnia, dreaminess, alopecia, giddy.The multi-frequency electromagnetic wave particularly direct result of high frequency waves and stronger electromagnetic field effect human body is to cause unconsciously people's energy and strength dissolved, produce easily cataract, leukaemia, brain tumor, angiocardiopathy, brain dysfunction and women's Abortion and sterility etc., even cause the low of human immunity function, thereby cause the pathology such as cancer.Statistical data shows: among the crowd who works before the computer of being everlasting, the incidence of disease of above-mentioned disease is apparently higher than the general population.And also do not have at present a kind ofly can carry and meeting or exceeding when setting limit value the device that can automatic alarm prompting people leaves when electromagnetic radiation from environment of living in.
