There is no need to worry about radiation hazards when using cell phone jammers. Like mobile phones, the signals emitted by mobile phone jammers do have certain electromagnetic radiation. The working principle of the jammer is similar to that of mobile phones. For example, the chip it uses is the same as that of mobile phones, and it also emits electromagnetic signals. Therefore, it will also generate certain electromagnetic radiation like mobile phones.

Will all intensities of electromagnetic radiation harm human health? The degree of harm to the human body caused by mobile phone jammers cannot be cut off in one size fits all. It is related to the length of time the machine is turned on and personal physique. In fact, the national safety value of electromagnetic radiation intensity also has national standards. The national standard mentioned here is the public exposure derived limit of the "Electromagnetic Environment Control Limits" (GB8702-2014) updated by the State Environmental Protection Administration in 2014. This national standard stipulates the maximum limit of the safety value of electromagnetic radiation exposure, and the average value of the electromagnetic radiation exposure field strength of the public cannot be greater than 0.4W/㎡.

The mobile phone jammers produced by regular companies with production licenses are strictly tested by the environmental testing department, and the radiation intensity is below the maximum limit specified in the "Electromagnetic Environment Control Limits" (GB8702-2014). In this way, it can be understood that the radiation value of the mobile phone jammers produced is safe for the human body.

The transmission power of mobile phone signal jammers suitable for smaller spaces such as classrooms, examination rooms, and conference rooms is relatively small, and there are strict regulations on the installation location and installation height. For example, above the blackboard in the classroom and on the wall of the conference room, the straight-line distance from the cell phone signal jammer to the human body is usually more than 2 meters, which has reduced the harm of the electromagnetic radiation of the mobile phone signal jammer to the human body to below the safe value.

For high-power mobile phone jammers with a transmission power of more than 50W for the interference module, the electromagnetic radiation value is relatively high. When in use, a farther distance is required to enter the safe range of electromagnetic radiation.
