Does the mobile phone signal jammer have radiation?
The mobile phone signal jammer does not need to avoid radiation hazards at all. Like mobile phones, mobile phone signal blocker do have a certain amount of radiation.
The working principle of the mobile phone signal jammer is similar to that of a mobile phone. For example, the chip it uses is the same as that of a mobile phone, and it also needs to emit electromagnetic signals. Therefore, it, like a mobile phone, will also produce certain radiation to the human body. Are electromagnetic radiation of all strengths harmful to human health? The degree of harm of mobile phone signal jammers to the human body is not one-size-fits-all. It is related to the length of time the device is turned on and personal physique. In fact, the safety value of the national electromagnetic radiation intensity (ie field strength) is clearly stipulated.
The national regulations mentioned here are the "Regulations on Electromagnetic Radiation Protection" (GB8702-88) approved by the State Environmental Protection Administration on March 11, 1988 and implemented on June 1 of the same year. This regulation stipulates the safety value of electromagnetic radiation exposure for occupational and public groups. For example, for the public, for electromagnetic radiation with a frequency in the range of 30-3000MHz, in 24 hours a day, in any continuous 6 minutes, the average field strength cannot be greater than 0.4 W/m2.
Formal enterprises with production licenses, the mobile phone shielding devices produced have been inspected by relevant departments, and the radiation intensity is within the safety range stipulated by the state. Generally, mobile phone signal jammers suitable for small spaces such as classrooms and conference rooms have low power, and there are strict regulations on the installation location. For example, the distance between the classroom corridor and the wall behind the podium and the human body is usually more than 2-3 meters, which has reduced the harm of electromagnetic radiation to the human body to a safe value. For a small space, you must not blindly introduce a high-power mobile phone signal jammer (the shielding range is greater than the radius of 50M) for the sake of laziness and economy. "The electromagnetic field of a high-power mobile phone signal jammer is also strong, and a longer distance is required to enter the safe range.
The practice of judging the degree of harm of the shielding device across the board makes the regular shielding device manufacturers quite indignant. Having radiation and being harmful to the human body are two different things, how can we draw an equal sign? Just like mobile phones, microwave ovens, and TVs all have radiation, and some of them have quite large field strengths, but outside a certain range and within a certain period of time, this kind of harm can be ignored and will not cause irreparable damage to the human body. damage, so these products are widely used in society and not abandoned.
