Smart phone radiation on our body is still very serious, especially in the Internet and answer the time when the radiation is usually 5-6 times. So coincides with the hot days of smart watches, hi people on the intelligent device radiation problem quite interested in, then designed a few small experiments. To detect the smart watch is not there radiation?
Does smart watch have radiation?
Using the Estack ES-305A electronic radiation detector, which is a sophisticated intelligent electronic equipment, radiation measurement range, low frequency in the 0-200 volts / meter (low frequency radiation electric field strength), high frequency in the 0-2000 microwatt / square Cm (high frequency radiated power density). In terms of accuracy, the electric field strength is 0.1 volts / m and the power density is 1 microwatts / square centimeter. Frequency range of 20HZ-3000MHZ, induction axis for the single axis.
According to China’s “Environmental Electromagnetic Wave Hygiene Standard” shows that the electromagnetic radiation intensity and its frequency characteristics of the human body may cause potential adverse effects of the next bound, the ambient electromagnetic wave radiation Cartier love bracelet replica intensity standard is divided into two.
The primary standard is a safe area, which means that all people (including infants, pregnant women and sick and sick people) who live, work and live for a long time in the context of the electromagnetic wave intensity will not be affected by any adverse effects; Expansion of radio stations, stations and radar stations, etc., in its residents coverage area, must meet the specifications of a standard.
The secondary standard is an intermediate zone, which means that all populations (including infants, pregnant women, and elderly people who live and work and live) that have long lived, worked and lived under the ambient electromagnetic wave intensity may cause potential adverse reactions. Construction of factories and institutions, but not allowed to build residential homes, schools, hospitals and nursing homes, etc., have been built to take appropriate protective measures. More than two standard areas, the human body can be folder with harmful effects, in this area can be greening or planting crops, but prohibit the construction of residential and crowd activities of all public facilities, such as organs, factories, shops and theaters; In these areas already have these buildings, you should take measures, or limit the radiation time.
The transmit power of the mobile phone is microwave, and the allowable area of the primary area specified by the standard is <10 microwatts / square centimeter and the secondary zone is <40 microwatts / square centimeter.
Radiation intensity detection interface has two values, namely, the maximum radiation and instantaneous radiation Cartier love ring replica value. For the purpose of visualization, this test uses the maximum record value. When we detect, close the device to the DUT, place it for about one minute, and then read the maximum value.
Smart watch radiation test
Here to the shell of smart watches for example! Open the shell of the watch’s flight mode, the radiation detector head close to the smart watch, in the monitoring process, we have been operating the watch, a minute later, we read the value.
Fruit shell smart watch: flight mode maximum 2
Open the fruit shell smart watch wifi, connected to the company’s wireless network, because the shell does not achieve the page or microblogging Internet access, we can only switch to the real-time weather interface, and then click the update button, so the watch can ” Internet access “.
Fruit shell smart watch: connect wifi maximum value 217
Finally, the watch with the smart watch through the Bluetooth connection, so that mobile phones and watches can be synchronized through the Bluetooth information, we click on the mobile phone application GWatch time synchronization to make mobile phones and watches for Bluetooth communication, and then detect the communication process of radiation Peak.
Three test results:
Fruit shell smart watch transmit power maximum comparison (unit: microwatt / square centimeter)
Flight mode: 2
Connect wifi: 217
Connect to Bluetooth: 161
According to the test results, the watch in the flight mode when the radiation peak is very low, only 2 microwatts / square centimeter, the impact on the human body can be ignored; connected wifi Internet, the peak can reach 217 microwatts / square centimeter, Also reached 161 microwatts per square Cartier nail bracelet replica centimeter, both of which exceeded the standard secondary area.
to sum up
1, smart watches, smart phones in the use of wifi network than when the wireless network is not used when the radiation value of 80-100 times, no time to find thousands of times the situation.
2, smart watches, smart phones Bluetooth connection, the radiation is not even if the connection wifi network, but the peak than the standard secondary area, radiation safety can not be ignored.
3, smart watches, although small size, when the internal structure is very similar with the phone, radiation is almost comparable to smart phones, so remind users to wear a serious understanding of the product before the radiation and personal acceptance of radiation, such as pregnant women is not too Suitable for wearing smart watches.
