Is it harmful to wear a backpack-type mobile phone signal blocker?
Backpack-type mobile phone signal blockers, also known as portable mobile phone signal blockers, are mainly designed for outdoor use or to deal with temporary emergencies. Because of their backpack-like appearance, ordinary adults can easily carry them anywhere. However, customers often worry that wearing such backpack-type mobile phone signal blockers will cause potential harm to the human body, especially the brain.
It is understandable that customers have such concerns. Regarding this issue, it should be noted that backpack-type mobile phone signal blockers have built-in shielding modules, and their radio frequency transmission power is usually between 10 and 20 watts. When the device is running, when the antenna is close to the human body, it will still emit some electromagnetic radiation, although the intensity is certain. However, it should be emphasized that electromagnetic radiation is not equivalent to nuclear radiation, and it is not as terrible as some people imagine. The potential harm to the human body is far less serious and worrying than people generally believe.
If medium-power mobile phone signal blockers such as backpacks are only used for a short time, rather than repeatedly used throughout the day, the impact of such limited electromagnetic radiation on the human body can be almost ignored.
In addition, these backpack-type cell phone jammers are usually powered by built-in batteries and can only be used continuously for 1 to 2 hours, so they do not produce long-term electromagnetic radiation to the human body.
Finally, it is worth mentioning that in actual application scenarios, unless it is used by the military, special police or personnel performing specific tasks under special circumstances, mobile phone signal jammers are usually not operated in a backpack state. In most cases, backpack-type mobile phone signal jammers are mainly designed for easy carrying and rapid deployment to the target location, rather than for long-term continuous use during exercise.
