Electromagnetic oven radiation can also be called "electromagnetic oven leakage radiation". Although the radiation frequency of induction cooker is about one sixtieth of that of mobile phone signal, the power that really determines the radiation size is much larger than that of mobile phone signal. This radiation power mainly depends on the leakage value of electromagnetic wave of induction cooker. The greater the leakage, the greater the harm to users. Because this kind of harm is invisible to our naked eyes, induction cooker is called "invisible killer", and long-term or long-term use will have a great negative impact on people's health.
