Radiation can be roughly divided into ionizing radiation and non-ionizing radiation. Except for ionizing radiation, most of our homes are facing non-ionizing radiation, and among non-ionizing radiation, high-frequency radiation has the greatest influence on people.
When it comes to home appliances, what people hear most and worry most is probably electromagnetic pollution. In fact, electromagnetic radiation is very common at home, because electronic components such as coils are widely used in household appliances. It is no exaggeration to say that objects with electromagnetic coils radiate when they work, but it is only a matter of the size of the radiation and whether it is shielded.
When it comes to electromagnetic radiation, I'm afraid the microwave oven and induction cooker are the first things you think of. For microwave ovens, there is usually a complete metal shell and a small protective plate outside the body. In addition, the sliding door of the microwave oven has a protective lock, so the microwave leakage is limited. Moreover, when using the microwave oven, few people need to stick it and stare at the food, so it is less harmful to people.
In contrast, the electromagnetic radiation of induction cooker is much more open. The induction cooker will produce extremely low-frequency electric and magnetic fields in the working process. Because it is separated from the metal heating object, the electromagnetic radiation of the induction cooker is tens or even hundreds times higher than that of ordinary household appliances, but fortunately, the induction cooker radiates upwards. In other words, as long as the side shielding of the induction cooker is safe and effective, and the operator keeps a certain distance from the side, there is no problem in normal use. However, the induction cooker needs people to keep a close distance when using it, so its radiation impact is much greater than that of TV and computer.
