The roasting stove has radiation. As long as everything that uses electricity has radiation when it works, but the working principle of electric oven is different from that of microwave oven, which relies entirely on radiation. In fact, electric oven, like water heater, generates high temperature after the electric wire is electrified.
According to experts from China Household Electrical Appliances Research Institute, in people's daily life, almost all electrical appliances have radiation, and judging whether they are harmful to human body depends on the level of radiation frequency. Anyone who knows a little about medical knowledge knows that electromagnetic waves are not "invisible killers". If they are used reasonably, they will also have a good effect on people's health.
Many hospitals have "physiotherapy rooms", which are dedicated to treating people with electromagnetic waves. Many families also have some "physical therapy equipment" to treat diseases or health care, which also shows that electromagnetic radiation is not necessarily harmful. According to experts, the radiation frequency of induction cooker is only one sixtieth of that of mobile phone. Therefore, electromagnetic wave is not an "invisible killer". If it is used reasonably, it will also have a good effect on people's health. Consumers can use it with confidence.
Extended information:
Common electromagnetic radiation sources: generally speaking, radar systems, televisions, mobile phones and broadcast transmission systems, radio frequency induction and medium heating equipment, radio frequency and microwave medical equipment, various electrical processing equipment, communication transmitting stations, satellite earth communication stations, large-scale power stations and power transmission and transformation equipment.
division of radiation field: electromagnetic radiation field is generally divided into far field and near field.
Near-field and its characteristics: the area within a wavelength range centered on the field source is usually called near-field and can also be called induction field. The near field usually has the following characteristics: in the near field, there is no definite proportional relationship between the electric field intensity and the magnetic field intensity.
regional field and its characteristics are called far-field and radiation field, which is centered on the field source and has a radius of one wavelength. The main characteristics of the far field are as follows: in the far field, all electromagnetic energy is basically radiated and propagated in the form of electromagnetic waves, and the radiation intensity of this field is much slower than that of the induction field.
