　　The concept of Bluetooth headset

Bluetooth headset is the application of Bluetooth technology in the headset, so that users can be exempted from annoying wire, easy to talk in a variety of ways. Since the advent of Bluetooth headset, has been the action of business people to improve the efficiency of a good tool. Bluetooth is a low cost and large capacity of short distance wireless communication specification. Bluetooth notebook computer, is a Bluetooth wireless communication function of the notebook computer. The name of the Bluetooth is also a legendary story. In 10th century, the Nordic warlords hegemony, the Danish king to stand up, in his unremitting efforts, the bloody war was stopped, all parties sat to the negotiating table. Through communication, the princes animosity, become friends. Because the Danish king loves to eat blue plum, so that teeth are dyed blue, called Bluetooth king, so, Bluetooth has become synonymous with communication. Today, 1000 years later, when new wireless communication standards are introduced, people use Bluetooth to name it. 1995, Ericsson first introduced the concept of Bluetooth. The Bluetooth specification uses the microwave frequency band work, the transmission rate 1M bytes per second, the maximum transmission distance 10 meters, by increases the launch power may reach 100 meters. Bluetooth technology is open to the world, in a global scope has a very good compatibility, the world can be through low-cost invisible Bluetooth network connected into one.

　　The concept of radiation

Radiation refers to a part of the electromagnetic energy from the field source from the field source to the distant transmission, and then return to the field source of energy, electromagnetic waves or particles (such as alpha particles, beta particles, etc.) in the form of diffusion outward. All objects in nature, as long as the temperature at the absolute temperature of more than 0 degrees, are electromagnetic waves and particles in the form of constant outward transmission of heat, this way of conveying energy is called radiation.

The common radiation is solar radiation, electromagnetic waves and heat radiation. Common electrical radiation is electromagnetic radiation. Electromagnetic radiation and electromagnetic radiation pollution is two concepts, any charged body has electromagnetic radiation, when the intensity of electromagnetic radiation exceeds the national standard, it will produce negative effects, causing the human body of different lesions and hazards, this part of the standard electromagnetic field intensity of radiation is called electromagnetic radiation pollution.

　The radiation of the Bluetooth headset

A group of experts, such as the World Health Organization and IEEE, said the tests did not reveal that the radiation of Bluetooth products had an impact on the human body. Bluetooth products output power of only 1 MW, is the microwave oven power one out of 10,000, is the mobile phone (mobile) power of 1 per thousand, and, these output is only a small part of the body absorbed. Bluetooth on the human body than directly with the phone to answer the phone and trial traditional wired headphones, more green security, children and pregnant women can be assured to use.
