As some countries, museums and amusement parks have banned the use of selfie sticks, netizens are speculating about the possible reasons behind the ban. Is the radiation from selfie sticks really dangerous? On this issue, the family doctor online very lucky to invite the guangdong radiation protection association rong minghai President to answer for the netizens.

Speaking of radiation, we need to know how does the radiation from the bluetooth remote selfie stick come about?

Rong gave us a detailed explanation: when taking photos with selfie stick, the photographer did not directly touch the phone, but pressed the control button at the bottom of the device to send shooting instructions to the phone to complete the shooting. There are two popular selfie sticks on the market. One is connected to the phone via a transmission line, and the other is connected to the phone via bluetooth. The first kind of selfie stick has basically no radiation, while the one connected via bluetooth generates electromagnetic radiation. The bluetooth selfie stick is connected to the mobile phone through bluetooth, and when the bluetooth is connected wirelessly, the information will be exchanged between the controller and the mobile phone. The carrier of the information is the 2.4ghz electromagnetic wave. So when you take a picture with a bluetooth selfie, you generate electromagnetic radiation.

So, is the radiation generated by bluetooth selfie stick harmful to human body?

Rong pointed out that the power of bluetooth selfie stick is very small, and the electromagnetic radiation generated by it is very small. Compared with other electromagnetic radiation we are exposed to in our daily life, it is negligible. The electromagnetic radiation equipment exempted from management in the electromagnetic environment control limit (gb8702-2014) will not cause harm to human health. So, hipsters, selfie-takers, singletons, girls whose boyfriends don't take pictures... You can feel free to use it. Try to go further and further on the way of taking selfies.

The extreme popularity of selfie sticks has led to a wide variety of selfie sticks on the market, with varying degrees of quality. In order to go further on the road of selfie, you must have a selfie stick of good quality and safety.

How to buy a good quality and safe bluetooth selfie stick?

Some countries now regulate bluetooth-enabled selfie sticks, which rely on electromagnetic waves to communicate with phones. Such sticks must be tested to ensure they do not interfere with other devices using the same radio frequency. The federal communications commission (FCC) to import and use of radio frequency devices, including computers, fax machines, electronic devices, radio reception and transmission equipment, wireless remote control toys, telephones, personal computers and other may harm the personal safety of products is also have the FCC standards, sales of bluetooth in the United States since the shaft must meet the FCC technology standards.

Currently, there is no relevant standard for the quality of selfie sticks in China, especially for electromagnetic compatibility. Therefore, rong President suggests that when you buy bluetooth selfie sticks, you'd better choose professional brand and quality products.

In life, besides selfie sticks, there are also a lot of related bluetooth products, such as remote control, bluetooth glasses, bluetooth synchronous photography products and so on. As these bluetooth products are more and more widely used, some people worry about the potential radiation threat of excessive use of bluetooth products.

Are these bluetooth products also a radiation hazard?

Chairman rong minghai clearly pointed out that since the emergence of human beings, we live in an environment full of electromagnetic radiation. With the development of social economy, artificial electromagnetic radiation sources (such as radio and television transmitters, mobile communication base stations, etc.) are more and more, and the electromagnetic radiation level in people's environment is also increasing. Of course, humans have adapted to such an environment, electromagnetic radiation environmental background level will not harm human health.

In order to facilitate our life, the emergence of bluetooth remote control, bluetooth glasses, bluetooth photography products, and so on, because these products are using electromagnetic waves for communication, so in normal work will inevitably produce electromagnetic radiation. However, these products belong to the electromagnetic radiation equipment exempted from management in the electromagnetic environment control limit (gb8702-2014), and the electromagnetic radiation generated is extremely limited. As long as the product quality is guaranteed, there is no electromagnetic radiation risk during normal use. Of course, in order to reduce the electromagnetic radiation level as much as possible, we should try to turn it off when we are not shooting during the use process, and do not leave it on for a long time.

Also now a lot of countries, venues have some rules, such as South Korea, the national Palace Museum, the French Versailles palace, Notre Dame DE Paris, Rome, Italy, New York MOMA museum of modern art, Tokyo Disney parks, the British national gallery, premier league games, etc are not allowed to use the shaft, so please follow the local rules in the process of use.
