The day before yesterday, the following news broke out on the Internet——
[Daughter in law pregnant family knock door to door: you don't use WIFI] Netizen @ FITTESTAROSA: There are family members in the building where we live now. It seems that his daughter-in-law is pregnant. They say that WIFI has radiation, which affects the health of daughter-in-law. They knock door to door to ask us not to use WIFI. I knocked on my door four times today. My WIFI has turned off the radio. He didn't believe me and said he would come in to see if I could use wireless routing
Does Wi Fi radiate? How much does it radiate? Is it really harmful to your body? Let me lead you to understand——
In fact, radiation is everywhere in life. In addition to Wi Fi, mobile phones, computers, printers, televisions, microwave ovens, induction cookers, hair dryers and other products with "electricity" will generate radiation. Even the biggest source of radiation in life is the sun. The electromagnetic wave band used by Wi Fi is generally 2.4GHz to 5GHz, which belongs to non ionizing radiation. The main reason is that the heating effect on human tissues may affect health, and it requires relatively high intensity to cause damage. Radiation is divided into ionizing radiation and non ionizing radiation. The energy derived from radiation depends on the frequency. The higher the frequency, the greater the energy. Ionizing radiation includes nuclear radiation, X-ray, such as hospital X-ray examination, CT, nuclear magnetic resonance, etc., which are harmful to pregnant women and fetuses; Non ionizing radiation includes electromagnetic fields generated by ultraviolet light, visible light, mobile phones, computers, high-voltage lines, substations, mobile phone base stations, television broadcasting, etc., which are less harmful.
What people usually call "electromagnetic radiation" is non ionizing radiation. For ionizing radiation, pregnant women must avoid it, otherwise it will harm the fetus and even the pregnant women's body. If you can't eat or feel restless due to radiation phobia, you can only say that there is no reason to worry! The current experiment proves that although Wi Fi network is more and more popular in work and life, its power is far below the national maximum limit of ionizing radiation, and even far below the radiation of mobile phone calls. As long as it is half a meter away from Wi Fi hot spots, the impact on human body can be ignored.
Question: What should you do if your neighbor is pregnant and asks you to turn off WiFi?
Method 1: Cancel SSID broadcasting, so that neighbors can not find direct evidence of using Wi Fi;
Method 2: Change the SSID name to CMCC/ChinaUnicom/ChinaNet, and let him find trouble with China Mobile/Unicom/Telecom;
Method 3: Close the door and do not see. If you have been knocking on the door and making a disturbance, contact the property management of the community directly or ask the police uncle to come forward;
Method 4: Tell the neighbors, "We do not produce radiation, we are only radioactive porters:)“
Method 5: Change the SSID to "Don't pretend to be serious if the child is mine" or "Your husband becomes pregnant as soon as he goes on a business trip"
