Phone stronger than cigarettes cause cancer or

What mobile phone radiation does not harm the human body? In this regard, marathon debate seems to have never stopped. Some time ago, the U.S. non-profit organization "Environmental Working Group (EWG)" tested the 1000 number of mobile phone SAR values (radiation absorbed by the human head, the ratio of soft tissue), discharge of the latest "top ten list of mobile phone radiation with ten difference." The results showed that the maximum radiation Motorola, Samsung cell phone radiation minimum. Among them, the BlackBerry Bold 9700 emission values achieved 1.55W/kg, received radiation "title" mobile phone in the title.

Not long ago, British experts discovered the latest research: the phone more carcinogenic than cigarettes. This has become the latest date on the phone, the most serious warning to mobile phone radiation concerns people referred to an unprecedented height.

Continuing controversy mobile phone radiation

According to statistics, about 30 million people worldwide use mobile phones, is 3 times the number of smokers. China's 1.3 billion people, mobile phone users has exceeded 700 million, that is, an average of at least one of the two people who own mobile phones. As the highest frequency of use of digital products, mobile phones a lot of people leave the body almost 24 hours.

All along, the world scientists are working on the real proven harmful levels of mobile phone radiation. They were classified into two factions, one optimistic that mobile phone radiation does not matter. The other faction is very cautious, often some of the more pessimistic news release that the phone may be hazardous to health in different degrees. Secretary-General of the World Mobile Communication Forum, said in a report Mike, the world over the past 20 years, 289 experiments have failed to find the mobile phone radiation harmful "evidence."

However, many medical experts believe that mobile phones must be to achieve the communication function to receive and transmit strong radio waves, in the process of using mobile phones, the strongest signal from the antenna is precisely the Ministry of the brain recently, it will certainly have a negative impact on the human brain. 2009 Sweden and several European countries found that, using the phone more than 10 years, may increase the risk of brain cancer and oral cancer risk. Dutch latest research also shows that mobile phone radiation is also associated with insomnia, Alzheimer's disease, child behavioral problems, infertility and other closely related.

Straight, compact, large cottage mobile phone radiation

"When people use the phone, the phone will transmit radio waves to the base station transmitter, and radio waves are absorbed by the body more or less, these waves is the mobile phone radiation, in descending order for the antenna, the Ministry of the Ministry of the handset, keyboard, and the Department of Ministry microphone. "senior electromagnetic environment experts, China Indoor Decoration Association Indoor Environmental Monitoring Committee Professor Zhao Yufeng told" Life Times "reporter:" cell phone radiation mainly from the antenna, including the external antenna and built-in antenna. "radiation intensity the distance from the body with the phone and is inversely proportional to distance double radiative decay times; shorten the distance doubles, the radiation intensity increased tenfold. View from the location of the antenna, external antenna, the radiation is larger than the built-in.

In the model of choice, straight from the head unit's antenna Recently, the radiation it the largest clamshell antenna furthest away from the head, so radiation small slide plane was somewhere in between. The function of the phone number, then no effect on the radiation intensity.

International Union of Radio Science Committee of electromagnetic noise and interference Professor Gao Yougang China Branch of the view that relatively large pocket of the mobile phone radiation. Mobile phone manufacturers in order to reduce electromagnetic radiation, usually located inside a metal cell phone shield, this layer can shield the electromagnetic radiation outside except the antenna into heat energy consumed. Phone volume is too small, the factory will be the size of the metal shield to make sacrifices, it may make it less filtering of electromagnetic radiation.

Mobile phone has become a cottage, "Radiation big." China Consumer Association Consumer Zhang Zhi, deputy director of the guidance department, said some mobile phone firms quality of raw materials, structural design, launch parameters are failed, the pursuit of power, in terms of radiation than the national standard, and some even exceeded 50 times.

Mobile phone radiation and also the distance between mobile phones and base stations, users around the geographical environment and other factors. "In previous years, relatively far distance between the base station, and city buildings of reinforced concrete structures will have a significant impact of electromagnetic waves, forcing the mobile phone and base station to increase power to get in touch, resulting in increased radiation intensity. Now the base station of a dense , the signal well, the phone do not need the original transmission power so great, the radiation is relatively reduced. "Zhao Yufeng stressed.

"Conservative usage" to reduce the radiation

In the country, people are "mobile phone radiation" does not seem concerned about the strong, the purchase of mobile phones, most people tend to pay more attention to appearance, brand, price, battery, ring tones and other "surface" factor. Zhao Yufeng, said many foreign mobile phone radiation will be marked or the instructions on the phone, but China has not the system.

Many studies have revealed that such a message: to call you inadvertently answered the phone, even in standby, mobile phone radiation are quietly hurting your body. In fact, health and convenience is not a contradiction. Several experts said the mobile phone in different states, will change the value of the radiation. Therefore, before the debate is not completely clear, "the conservative use of" potential harm can be minimized.

Long story short. Less mobile phone "talking on the phone," preparing for a long time the call should be to switch to fixed telephone or use headphones. If you have to use the phone directly to call a long time, they should be changed every 1-2 minutes with the other ear, the side of the brain in order to avoid long exposure to radiation.

Do not hang in the chest or waist. Often the phone against the waist or chest, which produces the radiation will affect people's fertility and cardiovascular function. Best to carry the phone in the package, and try to put it on the outer package. If you must carry a cell phone, make sure the keypad position toward the body, directed at the back of the body outside. Guangdong Provincial Occupational Disease Prevention Hospital Tangguo Han, MD, director of physical factors that make the phone when not placed in the 1-2 meters away from the body; sleep as much as possible should be shut down or put it in a place far away from the pillow. Heart failure, arrhythmia, especially those who can not phone hung on the chest.

Weak signal areas hit less. Differential signal power when the phone will automatically increase, resulting in the radiation intensity. For the same reason, in the elevator and other small, enclosed environment to use the mobile phone radiation will increase.

Then turn on the ear. Minimal standby mobile phone radiation, radiation when a large number of calls, while in the phone number has been allocated but not yet connected, the maximum amount of radiation is about 3 times when in standby. You should let the phone away from the head, the interval of about 5 seconds, then make a call.

Call, the phone not attached to the ear. University of Pittsburgh Cancer Institute, Dr. Ronald? Habermann suggested the body should maintain at least 5 cm distance. Mobile phone running out of power, charging is best not to call.

Do not answer the phone and moving. Do not walk around with a cell phone in the car or train, try to avoid using mobile phones. At this point try to connect phone constantly interrupt signal, will increase the maximum radiation.

Less metal wear glasses cell phone. This will obviously lead to enhanced electromagnetic fields, so that users of the radiation absorption rate increased. Best not to talk a long time, or both sides for a listen.

Using the wire headset. Although not directly use the headset, "wipe out" the radiation, but can isolate the human body and the radiation sources. In this case, the mobile phone radiation is only 1% of standard mobile phones. Phase comparison, the line Bluetooth headset radiation than the smaller.

Young people under the age of 16 is best not to use mobile phones. British researchers noted that young brain tissue fibers on the absorption of electromagnetic waves higher than adults, more susceptible to radiation damage.
