Whether it is a microwave oven with a relatively large amount of electromagnetic radiation, or an electric rice cooker that usually pays little attention to it, there is no indication of the amount of electromagnetic radiation on the outer packaging of the electrical appliance. Generally speaking, the greater the power of electrical appliances, the higher the amount of electromagnetic radiation TFT Display. The power of tablet computers is less than 100 watts. How can it be compared with a multi-kilowatt induction cooker. Of course, the electromagnetic cooker has a greater amount of radiation TFT LCD module.

    Almost all home appliances sold in the market are not marked with electromagnetic radiation, and the data measured by the electromagnetic wave radiation tester is not necessarily very accurate. For example, the electromagnetic radiation at the moment the TV is turned on is better than the electromagnetic radiation during normal viewing. The amount can be hundreds of times higher TFT LCD Display. In addition, the amount of radiation when the channel is changed is relatively large, and the manufacturer cannot come up with authoritative collection data 0.96inch TFT.

    Generally, the electromagnetic radiation of air conditioners, routers, electric heaters, refrigerators, washing machines and rice cookers is relatively small, which is within the acceptable range of the human body. The electromagnetic radiation of other home appliances exceeds this range. It is recommended that special people such as pregnant women should pay attention to prevention.

    Recently, a ranking list of household appliances radiation has been reposted in large numbers on the Internet. The ranking of home appliances radiation on this list is that induction cookers rank first, followed by hair dryers. Another list said that tablet computers have the most electromagnetic radiation, followed by hair dryers, and microwave ovens are ranked third, followed by electric blankets, old-fashioned televisions, induction cookers, mobile phones, desktop computers, and LCDs. Screen TV. However, neither the manufacturer nor the distributor can come up with specific data on the radiation of home appliances.

    The vast majority of consumers call for manufacturers to self-test, and then mark the electromagnetic radiation of home appliances like the energy consumption level, and then conduct random inspections by third-party testing agencies. In this way, consumers can know.
