2. The reason why the resistive radiation protection suit can prevent radiation is because the metal mesh inside the radiation protection suit forms a closed loop, which generates induced current. If there is current, there will be resistance. So we can test the radiation protection effect by detecting the size of the resistance. The greater the resistance, the weaker the current generated and the weaker the ability to shield the magnetic field in the opposite direction. On the contrary, the smaller the resistance, the stronger the current, the stronger the reverse magnetic field, and the better the radiation protection effect.
3, noise interference method first dial the phone, and then put the radiation protection suit halfway between the phone and the stereo, listen to whether there will be noise, the real radiation protection suit will have noise or trembling sound.
4. Identify the authenticity by the label of the security code. If the real radiation protection suit looks up the security code in official website, we can know the authenticity.
5. First, test the mobile phone you are using with the instrument to see what the radiation value is and record it. Then, cover the radiation protection suit on the mobile phone and test it again to see if the radiation value has weakened. This is a very intuitive method to see whether it really has radiation protection effect.
6. It is also necessary to remind pregnant mothers that many people on the Internet say that it is unscientific to wrap a mobile phone with a radiation suit to see if there is a signal. Because radiation and signal are two different things, radiation protection clothing can weaken the signal of mobile phone, but it can't completely shield it.
