1. Is there radiation when wearing headphones?
Radiation is everywhere in life. As long as it is an electronic product, it will radiate more or less after being powered on, but most of them are within the safe range and will not cause harm to the body. Listening to music with headphones has certain radiation, but it is within the safe range, so don't worry too much.
The main harm of headphones to human body is not radiation, but noise and sound waves, so when wearing headphones, you should control the volume and the time of wearing headphones to avoid hearing damage.
2. Can pregnant women wear headphones?
Many people have doubts that headphones are electronic products with radiation, so can pregnant women wear headphones?
In fact, pregnant women can also wear headphones to listen to songs. The radiation of headphones is very small, which can be basically ignored and will not affect the health of the fetus, so pregnant mothers can wear headphones with confidence.
attention! It is best not to wear headphones in a noisy place for pregnant mothers. When wearing headphones, the mobile phone should not be close to the belly. The radiation of the mobile phone is greater than that of headphones. Especially in the first three months of pregnancy, the fetus has not yet formed, and long-term use of mobile phones will have some influence on the fetus. Therefore, it is necessary to control the time of wearing headphones.
3. Does the Bluetooth headset radiate more or is it a wired headset?
In order to promote the Bluetooth headset, some businesses have put out the slogan "Bluetooth headset radiates less than wired headset", which is actually nonsense. Although the radiation of Bluetooth headset is one-tenth of that of mobile phone, and the radiation intensity is within the safe range, it does not mean that the radiation of Bluetooth headset is smaller than that of wired headset.
Bluetooth headsets transmit power by themselves, while wired headsets only have the function of receiving. In this case, the radiation of Bluetooth headset will be a little bigger.
4. How to avoid earphone radiation
The most effective way to completely avoid earphone radiation is not to wear headphones, but this is obviously unrealistic. So here I give you a few suggestions to minimize the impact of radiation on the body when wearing headphones.
1. Wear headphones, and choose wired headphones as far as possible
2. Choose high-quality and qualified headphones
3. Control the time to use headphones well
4. When listening to music with headphones, try to keep your mobile phone away from your body
5. Microwave damage in daily life
1. Microwave ovens
When they were first introduced, many people lost their jobs. Now the microwave oven is safe as long as it is one meter away.
2) Cell phone
When talking, electromagnetic waves close to the ear will harm the brain.
3) Commuter tram
Car _ Many people use mobile phones, and the tram becomes a mobile microwave oven.
4)IH△ conditioning furnace
It is dangerous for pregnant women to use! Electromagnetic waves can lead to miscarriage or an increase in deformed children.
6. What are the electrical appliances with high radiation?
First place: Radiation index of shaver
When the switch of shaver is turned on, the radiation value instantly reaches 19.59μt, which far exceeds that of microwave ovens, induction cookers and other electrical appliances, so all men and friends must try to reduce the use of shavers ~
Second place: Radiation index of hair dryer
The radiation value is 15.5 cm away from the outlet of hair dryer. Near the fuselage of the hair dryer, the radiation value reaches 18.49 μ t. If the hair dryer is used for a long time, it will also bring certain radiation damage to users.
3rd place: radiation index of the skimmer
The radiation of the skimmer reaches 18.29 μ t. Because the skimmer is used close to the body, and the use time is usually 1-2 minutes, the radiation impact is also very great.
4th place: radiation index of electric blanket
When the electric blanket is turned on, the radiation value is 16.69μt, and it will also generate great radiation when it is running. Therefore, users are advised to turn on the electric blanket as early as possible when using it, and it is best to turn off the electric blanket when sleeping, so as to avoid its high radiation.
5th place: mobile phone radiation index
When the mobile phone is in standby, the radiation value of the mobile phone is basically . During the call, the radiation value of the mobile phone instantly reaches about 3μt, which is far greater than the safety value of .2 μ t. Because the mobile phone is usually attached to the head at close range, the long-term call has a greater impact. It is recommended that users use headphones to answer.
6th place: radiation index of induction cooker
When the induction cooker is in operation, it exceeds the safe radiation standard (.2μt, the higher the radiation, the greater the radiation), of which 19.74μt is at 1 cm. However, as the distance is extended, the electromagnetic radiation rapidly decays, and it has already met the safety standard at 4 cm. Therefore, it is recommended to keep a distance of half a meter when using the induction cooker, so that it can be guaranteed.
7th place: radiation index of microwave oven
When the microwave oven is running, the radiation value at the distance of -65cm from the main entrance decreases sharply, and the radiation value at the distance of 7cm from the main entrance is zero. Therefore, it is suggested to stand one meter away from the microwave oven when using the microwave oven, so as to effectively avoid the harm caused by microwave radiation.
8th place: radiation index of desktop computer
When testing the LCD screen, the radiation value is zero at a distance of 1 cm from the screen, and it is .23μt close to the screen, which basically meets the safety standards, so the radiation of the LCD screen can be ignored.
the radiation value is zero at a distance of 2cm from the chassis, but the radiation value close to the chassis is more than 1.3μt, which is far higher than the radiation standard. Therefore, in daily use, it must be at least 2cm away from the chassis to ensure safety.
9th place: the radiation index of notebook computer
The radiation value shows zero at a distance of 3 cm from the notebook computer, and it still shows zero at a distance of 15 cm when approaching the notebook computer. When approaching the edge of the notebook computer, the radiation value shows 1.6μt, and the radiation amount meets the safety standards.
However, when the radiation instrument is located above the notebook keyboard, the radiation value quickly climbs to 13.96μt, and the radiation value close to the LCD screen reaches 14.61 μ t. Although the radiation value exceeds the safety standard, as long as we keep a distance of more than 2 cm when using the notebook, there will be no radiation hazard.
1th place: radiation index of drinking fountains
During the heat preservation or heating process of drinking fountains, the radiation of drinking fountains rose from zero to .3μt, which was completely within the safe range.
