How much radiation is shortwave outside the body? Does it accumulate in the body? What are the effects of prolonged exposure on the body?

Short wave is a kind of electromagnetic wave, wavelength 1 ~ 10 meters, frequency 3 × 107 ~ 3 × l08Hz, the human body is always in a certain amount of energy in the electromagnetic radiation environment, when its frequency is more than 105HZ above the human body is harmful. To say in vitro short-wave side effects, should be from the intensity of radiation, the main radiation orientation and the distance from the source of radiation, duration and other aspects of the comprehensive consideration, the greater the output power of the electromagnetic wave radiation source, the greater the intensity of radiation, the shorter the wavelength, the higher the frequency, the closer the distance, the longer the contact time, the higher the temperature of the environment, the higher the humidity, the more the air does not circulate, the greater the degree of pollution of the environment and the human body, and the women and children by the hazardous More serious. The extracorporeal short wave therapeutic instrument you mentioned is a high-energy, high-power, short-wave emission source, long-term exposure to its excessive radiation will be harmful to the body. A healthy body is in a moderate dynamic balance. What excessive, excessive will have different degrees of physical harm, should pay attention to but also can not overstate the harm, subject to electromagnetic radiation, who can not be avoided, especially when you are in the hospital, contact with medical equipment, it is more unavoidable. The important thing is that you have to have a sense of precaution, at the same time to rationally look at it, can not be overly panicked, usually work, pay attention to in addition to the work must be, usually should try to minimize the contact with medical equipment, each time as short as possible, the distance as far away as possible. Pay attention to observe their own physical conditions, including physiological and psychological, pay attention to whether the physiological rhythm is disturbed, whether often headache, dizziness, insomnia, forgetfulness and the human body heat regulation system disorder caused by the heart rate, blood pressure increased or decreased; and physiological such as menstruation is not a significant change. Radiation is unavoidable, but individuals can effectively attenuate or eliminate the effects of radiation through conscious precaution and prevention. Like in addition to work must, usually should minimize contact with medical equipment, each contact time as short as possible, distance as far away as possible. Diet, I see that some experts suggest that you can take a certain amount of vitamin C every day, or eat more vitamin C-rich vegetables, such as chili peppers, persimmon peppers, parsnips, cauliflower, spinach, garlic shoots, potherb mustard, kale, cabbage, water rooibos, red rooibos, sweet potatoes, etc.; eat more fresh fruits such as citrus, jujube, strawberry, hawthorn and so on. Pay attention to eat more food rich in vitamin A, C and protein, such as tomatoes, lean meat, animal liver, bean sprouts, etc.; through these dietary measures, it is beneficial to strengthen the defense function, but also to a certain extent can play an active role in preventing and mitigating the harm caused by electromagnetic radiation on the human body. Electromagnetic radiation on the role of people have an accumulation process, when it reaches a certain level will produce obvious harm to people, to have a sense of precaution, at the same time can not be overstated, panic. You have to contact this equipment in the obstetrics department? If the work needs, you usually have to have a sense of precaution, the above precautionary measures you look at, pay more attention in the work.
