Recently, Zhuzhou Ms encounter something bothering. End of July, when she and her boyfriend "talking on the phone," I suddenly felt the phone warms, and so take away the sting felt face, and erythema after a month has not eliminated. Doctors diagnosed as "electric radiation burns."
So why call Needless long red marks will be formed on the face? "Electrical radiation burn" is how it happened?
Culprit is not the "mobile phone radiation"
Online search can be learned, "electric radiation burns," the term is after the incident was reported to occur in large quantities, it had not previously been reported. The emergence of this new term so many people on the phone's security into question, and even that is a result of cell phone radiation burns, which is actually a misunderstanding.
Nuclear radiation and high-energy radiation produced by radioactive materials, such as X-rays, neutrons, etc., can indeed be formed scalded symptoms on the skin, but this is actually a very high frequency electromagnetic waves and high-energy particles can be ionized atoms, can directly kill tissue caused so this type of radiation is also known as ionizing radiation. Generally in life difficult to access these sources, there will be no more such devices inside the phone. In addition to mobile phones, is just the electromagnetic radiation, non-ionizing radiation in the microwave band, and low-power mobile phones work at 250 milliwatts or less (as a comparison, the brain's own power of about 20 watts, which is about 80 times the former ), such a low-power does not produce any thermal effect to cause burns. Therefore, the public do not have to "mobile phone radiation" and panic.
Low-temperature burn is the mastermind
Ms from the description of view, she was feeling "hot phone" produced only after scald symptoms. Therefore, the most likely cause of the symptoms to watch over, low-temperature burns.
Usually in the awareness, the burns are caused by hot objects. But in fact, received burns and tissue is directly related to the heat, the temperature level is just one factor to cause burns, and another factor is the heat source and the contact time. At relatively low temperatures, long contact time, can lead to tissue damage caused by excessive absorption of heat.
For human tissues, in the skin after exposure to heat, the heat through the epidermis to the dermis and deeper delivery, resulting in temperature increase. Because human tissue heat capacity and thermal effects of subcutaneous blood, eventually forming a heat absorption - circulated balance. Thus causing burns or not there is a temperature threshold and time threshold. It is generally considered to be below 42 heat source in contact with skin does not cause low-temperature burn, and when the temperature is above 44 , that is possible to form a low-temperature burn. The low-temperature burn severity with increasing contact time and increase the temperature of the heat source and serious. 44 heat source such as six hours exposure can lead to irreversible changes in the epidermal basal cells, and 49 heat contact with the skin can cause skin damage 3 minutes, more than 9 minutes epidermal necrosis that is possible. Animal experiments also show that more than 45 temperature can cause cryogenic burns.
For Ms this case, a long time, "talking on the phone," and the resulting increase in the temperature of the phone, both of which constitute the necessary conditions for the low-temperature burn. According to evaluation agencies show mobile phone, the phone about 1 hour continuous operation temperature generally can reach more than 40 , some of the models can be as high temperature near 50 , low-temperature burn has exceeded the safety threshold. Therefore, talking on the phone cause the phone to temperature rise, and prolonged exposure to the face, is an important factor Ms caused burns.
The elderly, young children with particular attention to low-temperature burn prevention
Low-temperature burn due to the long exposure time and the heat source, it is often cause deep tissue damage, burns up the deep level II degrees to degrees III. And because the surface is usually only redness or blisters, a "Tripe big mouth" of tissue damage zone, not carefully check it may only be judged as superficial burns, thus delaying treatment. For Ms, because timely isolation heat source, resulting in only the erythema, but for the elderly and young children, low-temperature burn injuries may be caused not only that the erythema.
Cryogenic burns caused by the elderly and more as winter hot water bottle, occurs when the heating or hot water kettle feet. Since the elderly often have the habit of hot feet, while the elderly extremities of the nervous system and circulatory system is poor, the water temperature has exceeded a safe temperature situation still feel, while heat deep within the organization can not be discharged, thereby forming low-temperature burn. The elderly, especially in diabetic patients respond to low-temperature burn sufficient vigilance, because once formed is difficult to restore burns, can cause severe tissue infection and even amputation.
For young children, parents are eager to cold, warm items of clothing placed inside an important cause cryogenic burns. And since children can not fully express the feeling of heat caused by prolonged skin contact burns can not reflect, when often found to have caused serious burns.
In summary, the low-temperature burn is a country with serious harm, but many people do not understand the type of burns. Therefore, when heating for the elderly and young children, should particularly pay attention to the temperature of heating the article and placement is appropriate. Diabetic patients should avoid contact with the skin above the safe temperature items. For when the young people, using infrared light and other physical therapy also should be noted that the irradiation distance and exposure time, in addition to avoid concentrate on a call, and other hot bubble behavior in case of contact with the heat source, in order to avoid low-temperature burn.
