1. National Safety Standards for Wi-Fi Radiation.1) According to the safety limits set by the International Commission on Non-Ionizing Radiation Protection, the safe radiation range for the human body is “10 watts/square meter”.2) The electromagnetic wave frequency range of Wi-Fi signals is generally from 2.4 GHz to 5 GHz, which is quite close to the radio frequency electromagnetic wave range used by mobile phones.3) Currently, the radiation values of Wi-Fi are usually at the milliwatt per square meter level, far below the safety limit of 10 watts per square meter set by the International Commission on Non-Ionizing Radiation Protection.2. How Much Radiation Does Wi-Fi Emit?1) Radiation intensity is inversely proportional to distance.2) Common household wireless routers operate at a power range of 30 to 500 milliwatts. According to expert tests, the power density measured 1 cm away from the Wi-Fi antenna is 9.1 microwatts/square centimeter (small enough to be negligible).3. How Pregnant Women Can Protect Against Wi-Fi Radiation.1)Please do not install the wireless router in the bedroom; it is recommended to install it in the living room or study. The further away, the lower the radiation exposure.2) When purchasing a router, it is best to choose products from reputable manufacturers. Additionally, it is advisable to select routers with lower power output, as they emit less radiation, which is more beneficial for the health of pregnant women and babies.
