The report noted that the potential effects of radiation on the human body can be categorized into two areas -- thermal and vibration. However, under the safety guidelines for cell phone radiation, the human body has a very small chance of being affected by microwave heat and a larger chance of being affected by microwave vibration.
It turns out that when the intensity of microwaves exceeds a certain standard, the body's temperature will rise, and if the temperature rises by one degree Celsius, health problems will arise. Some parts of the body less blood flow through, such as the eyes and testicles are most likely to be affected, there may be cataracts and sperm reduction, which is known as the "heat effect.
In fact, current cell phones have established microwave intensity limits, and the general amplitude of cell phones is much lower than this standard, which will not lead to cataracts and reduced sperm count.
However, the report also pointed out that the GSM frequency of cell phone system common in most countries is 900 and 1800MHz, and its vibration of electronic process has the chance to affect human health, mainly on the brain and mental state.
Many studies have shown that the vibrations can cause reduced sleep quality, memory impairment, increased blood pressure and headaches. In addition, cell phone radiation may also cause epilepsy, just as a certain frequency of flashes of light can cause epilepsy.
However, the effects don't always occur and vary according to a person's physical and mental state. For example, a person who is constantly under stress has a greater chance of being affected. In addition, the report also points out that as children's skulls are smaller and thinner, they can easily absorb the microwaves from GSM, and children's immune systems are weaker, so their chances of being affected by cell phone radiation are also higher. Therefore, the report suggests that children should use cell phones less.

Where is the lowest radiation level for a cell phone? 2005-04-04 10:32:18 Netizen Comments 84 Dialing is particularly radioactive Try to stay away from your body
With the development of wireless communication technology, more and more people are using cell phones. The health problems associated with cell phones have also attracted more attention. The radiation of the cell phone in the end how much harm to the human body, how to minimize the degree of harm, has become the most concerned about the issue of cell phone users.
When people use the cell phone, the cell phone will transmit radio waves to the transmitting base station, and the radio waves will be more or less absorbed by the human body, these waves is the cell phone radiation. Generally speaking, cell phone standby radiation is smaller, call radiation is larger, and in the cell phone number has been dialed and has not yet been connected, the largest radiation, radiation is about three times the standby. These radiations have the potential to alter human tissues and adversely affect human health.
Mobile phones do not put the pillow side
According to the China Interior Decoration Association Indoor Environment Monitoring Working Committee, Professor Zhao Yufeng, cell phone radiation on the human head is more harmful, it will be on the human central nervous system caused by dysfunction, causing headache, dizziness, insomnia, dreaming and hair loss and other symptoms, and some people's faces will also have a sense of irritation. In the United States and Japan, there have been many suspected cases of brain tumors caused by cell phone radiation. In July last year, a man in Maryland, USA, who suffered from brain cancer, filed a lawsuit against his cell phone manufacturer after he believed that the use of his cell phone had caused him to develop cancer. A study published in the European Journal of Cancer Prevention also pointed out that people who use cell phones for a long time have a 30% higher chance of developing brain tumors than those who don't. People who used cell phones for more than 10 years had an 80% higher chance of developing brain tumors than those who did not use cell phones. Therefore, when people answer the phone, it is better to take the cell phone to a distance away from the body to connect first, and then put it to the ear to talk. In addition, try not to chat on your cell phone, and be careful not to put your cell phone next to your pillow when you sleep.
Don't hang your cell phone on your chest
Many girls like to hang their cell phones on their chests, but studies have shown that hanging a cell phone on your chest can have an impact on your heart and endocrine system. Even in standby mode with less radiation, the electromagnetic radiation around the cell phone can cause harm to the human body. People with heart insufficiency and arrhythmia should be especially careful not to hang their cell phones on their chests. Some experts believe that electromagnetic radiation will also affect the endocrine function, leading to female menstrual disorders. In addition, electromagnetic radiation will also affect the normal cellular metabolism, resulting in the body of potassium, calcium, sodium and other metal ions disorder.
The cell phone is generally equipped with shielding equipment, can reduce the radiation damage to the human body, containing aluminum, lead and other heavy metals shielding equipment protection effect is better. However, women for the sake of beauty, often choose a small cell phone, this phone may not be enough to protect the function of the phone, therefore, in the absence of both small, protective function and strong cell phone, female friends best not to hang the phone in front of the chest.
Hanging on the waist affects fertility
According to a June 28 report in the British newspaper The Times, Hungarian scientists have found that the number of spermatozoa in men who regularly carry and use cell phones can be reduced by as much as 30 percent. Some medical experts pointed out that if cell phones are often hung around the waist or abdomen, the electromagnetic waves generated when sending and receiving signals will radiate to the sperm or eggs in the human body, which may affect the user's reproductive function. The British experimental report pointed out that the mouse by the cell phone microwave radiation 5 minutes, will produce DNA lesions; human sperm, eggs, long time by the cell phone microwave radiation, may also produce DNA lesions.
Experts recommend that cell phone users try to keep the phone away from the waist, abdomen, do not hang the phone on the waist or in the coat pocket. Some men tuck their cell phones inside their pants pockets, which poses the greatest threat to sperm because the pants pockets are right next to the testicles. It is best to set the cell phone aside when the user is in the office, at home or in the car. When out and about, the cell phone can be placed in a purse so that it is farther away from the body. Using a headset to answer a cell phone can also be effective in reducing the effects of cell phone radiation.
