Cordless phones and mobile phones, which are less harmful to the human body?
It is reported that the National Radio Management Committee at the end of last year has dealt with a number of high-power cordless phones, which are foreign, there are domestic brand-name manufacturers, among them, some models up to 3 watts of output power is about 50 times more than the national standard, cordless phones will not only seriously interfere with radio service normal, caused by electromagnetic pollution, but also to the user's health also have adverse effects, therefore, buy cordless phone or choose well-known brands at home and abroad as well
We might all use GSM mobile phone and cordless telephone on a mobile phone, most of the transmit power of 2 watts, the frequency is 900 MHz, the transmit power of the mobile phone is 100 times the cordless phone, and the use of high frequency transmission. There is no definite scientific basis for whether cell phone radiation will cause harm to humans, and the use of cordless phones with negligible power radiation is almost unnecessary.
Cordless phones are very small compared to mobile phonesThe larger the transmitting power of the cordless phone, the farther the calling distance is, the greater the radiation of the electromagnetic wave; and the cordless telephone, which meets the national standard, will not affect the human body. China Radio Management Committee clearly stipulates that the transmitting power of cordless telephone set, the machine shall not exceed 20 MW, the open call distance of about 300 meters, and the frequency between 45 to 48 MHz for cordless phone use, radiation power is so small in the low frequency range is very small.
