Does the mobile phone signal jammer have radiation?

Like mobile phones, mobile phone signal blockers emit certain radiation. However, it should be noted that mobile phone signal blockers do not need to be avoided simply because of radiation hazards.

The working principle of mobile phone signal blockers is similar to that of mobile phones. They use chips similar to mobile phones to emit electromagnetic signals. Therefore, mobile phone signal blockers, like mobile phones, will also generate radiation and have an impact on the human body. However, not all levels of electromagnetic radiation will cause harm to the human body. The degree of harm caused by mobile phone signal blockers depends on factors such as the length of time the equipment works and personal physical condition. In fact, national laws and regulations have clear provisions on the safety limits of electromagnetic radiation intensity (i.e. field strength).

The regulations mentioned here refer to the “Electromagnetic Radiation Protection Regulations” (GB8702-88) approved by the State Environmental Protection Administration on March 11, 1988 and implemented on June 1 of the same year. These regulations stipulate the safety limits for occupational and public groups to be exposed to electromagnetic radiation. For example, for the general public, within 24 hours a day, the average field strength of electromagnetic radiation in the frequency range of 30-3000MHz shall not exceed 0.4W/m2 in any continuous 6 minutes.

Qualified and licensed cell phone jammer manufacturers will ensure that the radiation intensity of their products is within the safety range specified by the state. Mobile phone signal jammers designed for small spaces such as classrooms and conference rooms generally have low power and 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 generally set at more than 2-3 meters, which can effectively reduce the potential hazards of electromagnetic radiation to a safe range. In a small space, do not introduce high-power mobile phone signal jammers (shielding range exceeds 50 meters radius) at will for convenience and cost saving. The electromagnetic field of high-power mobile phone signal jammers is also very strong, and a large distance is required to maintain a safe range.

Treating all shielding devices as generally harmful has caused dissatisfaction among legitimate manufacturers of such devices. Having radiation and being harmful to the human body are two different things and should not be equated. Just like mobile phones, microwave ovens and televisions, they all emit radiation, some of which have relatively large field strengths, but their potential hazards can be ignored within a certain range and time. They are widely used in society and have not been abandoned because they do not cause irreversible harm to the human body.
