Radiation from nuclear power plants is terribly terrible. The radiation of household appliances cannot be ignored. In a family, the health of the family has always been our concern. In addition to televisions, refrigerators, washing machines, and microwave ovens, our home appliances include cell phones, telephones, and tablet computers. How much radiation do they have? Will it affect our physical health? The author will then discuss with you the issue of the radiation of household appliances. Interested friends may wish to find out.

What is the radiation intensity the human body can withstand?

Scientists currently believe that it is safe to have long-term exposure to electromagnetic radiation below 2 milligauss (approximately 20 μW/cm2). However, any form of artificial electromagnetic radiation has an effect on human cells. In order to prevent electromagnetic radiation pollution and protect public health, since the 1990s, the National Environmental Protection, Health, and other departments have successively formulated and issued seven regulations and national standards such as “Sanitary Standards for Environmental Electromagnetic Waves”, and stipulated grading standards for electromagnetic radiation:

A standard (safety standard, no effect on the human body) High-frequency radiation less than 10 μW/cm2

Low-frequency radiation less than 10 V/m

Secondary standard (middle zone, which has a detrimental effect on the human body) High-frequency radiation less than 40 μW/cm2

Low frequency radiation less than 25 V/m

In understanding the above radiation values, let us first understand the conversion of the radiation value, 100μw/cm2 = 10 milligaussian = 1μt, this time we measured the value of the radiometer is "μT" as a unit, so less than 0.1 μT is an absolute safety range, and 0.1μT-0.4μT is in the secondary standard range, but it can have harmful effects on the human body.

The household appliances in our home are mainly magnetic radiation, and the frequency bands are divided into industrial and radio frequency bands. The work frequency bands mainly include televisions, computers, hair dryers, refrigerators, etc., and the unit is μT. The radio frequency bands mainly include mobile phones, microwave ovens, and the like, and the unit is μW/cm2. In the next evaluation, we will perform tests and numerical conversions based on the corresponding frequency bands. The following are the radiation star types of various types of home appliances and electronic equipment: (five stars, is a serious violation, to pay attention; Samsung above, is beyond the scope, but also to attract attention; a star, safe, can be used with confidence), hoping to cause people Attention.

Five-star home appliance radiation: ★★★★★

1. Microwave oven: The radiation at the door seam is the largest, the radiation at the start is the maximum, and the cooking should not be too close. The radiation range can reach 7 meters.

2. Electric blanket: After the electric blanket is energized, it will produce an electromagnetic field and produce electromagnetic radiation. If pregnant mommy uses electric blankets for a long period of time, these electromagnetic radiations will most likely affect the fetus's brain, nerves, bones, and heart and other vital organs and tissues.

3. Humidifier: The radiation of the humidifier, which is particularly favored by women, is so large that it should never be placed too close to the body. It is close to 100 milligauss and drops to 1 milligauss after leaving 1m.

4. Vacuum cleaner: 50 milligauss at 30cm, 70cm can be reduced to 2 milligauss. Stay away from being better.

5, fat exercise machine: the front of the conveyor belt radiation is large, exercise time should not be too long, to minimize radiation.

Four-star home appliance radiation: ★★★★☆

1, high-power equipment: the moment of radiation when connected, do not put on the bed.

2, hair dryer: Although small, but the radiation is great, use should be away from children. When opening and closing the hair dryer, try to stay away from the head. When using it, it is best to keep the hair dryer perpendicular to the head. Do not use it for a long period of time.

3, CRT TV: that is, ordinary television, behind the radiation is greater, need to maintain a certain distance when viewing, especially children. It is best to maintain a distance of 2 meters when watching TV. There is proper lighting in the room. Do not watch TV for more than two hours continuously. After watching the TV wash your face, clean up the radiation absorbed by the facial skin.

4, home theater: usually refers to the video player plus audio system, as little as possible, if you want to sing best go to KTV.

5, subwoofer speakers: Most computer speakers are very close to the computer, experts recommend using at least half a meter away from the body to keep at least half a meter distance, especially connected to the computer's subwoofer speakers, should not be placed near The position of the human brain.

6, infrared tube heater 7, fan: use time not too long, and maintain a certain distance.

8, Induction Cooker: Now more and more families like to cook with electromagnetic oven, but pay attention to the use of time not too long.

9, the iron: the temperature once heated in place, use a while to continue heating, do not heat while ironing clothes. Keep away from children when using.

Three-star home appliance radiation: ★★★☆☆

1. Plasma TV: For traditional CRTs, the radiation of LCD TVs and plasma TVs is much smaller. However, there are still some adverse effects. It is recommended that the use time should not be too long.

2, desktop computer host: the host's rear, side radiation is large, it is recommended not to facilitate the heat dissipation, open the use of the chassis, reduce radiation damage to the human body.

3, wireless mouse and keyboard: Because it is a wireless mouse and keyboard, it will generate radiation when transmitting and receiving operating signals.

4, electric foot basin 5, air purifiers weaker electrical intensity is what?

Two-star home appliance radiation: ★★☆☆☆

1, range hood: Note that when using not too close.

2, electric baking pan 3, treadmill star radiation: ★ ☆ ☆ ☆ ☆

It also has low electromagnetic waves when not in use.

4, refrigerator 5, ozone disinfection cabinet 6, rice cookers: Although radiation is small, but as far as possible away from children.

Industrial Router

What is an industrial router? Which industries are they mainly used in?

With the continuous development of the network and the continuous progress of various industries, some new concepts and development directions have actually emerged during the period. For example, from the current point of view, many enterprises in the development process in order to have good efficiency and speed, as well as the use of more functions, gradually began to use industrial routers. Of course, for this type of router, we also have a lot of problems, so today we will discuss to see, what is an industrial router? Which industries are they mainly used in?

What is an industrial router?
From the basic concept, an industrial router is a wireless data transmission function that provides users with wireless data transmission through a public wireless network. For example, we use mobile phone data to transfer things to another mobile phone or computer, in fact, the principle is very simple. Of course, the specific usage operation is different. In the process of use, the industrial router has the advantage of allowing multiple users to use the same integrated network system to access the network, which is also very convenient in the work. In fact, at present, industrial routers are gradually widely used in different industries, and the practicability is also very strong.

Industrial routers are mainly used in what industries?
The first is some of the contents summarized for the concept and basic principles of industrial routers, and for the use of industrial routers, it is also some of the issues that we are concerned about. From the current point of view, the first is widely used in intelligent transportation, such as in the application of high-definition electronic bayonet, road wireless video surveillance, vehicle monitoring or security monitoring, etc., which is also very important; Secondly, it is also widely used in the financial industry, such as the use of wireless atm self-service terminals, wireless pos machines or other applications; In addition, it is the application of the power industry, such as transformer remote monitoring management, circuit line video surveillance and substation video surveillance and so on. In short, the use of industrial routers is also more extensive.

How to choose an industrial router?
Although the industrial router is widely used now, the choice we made at the beginning is still more tangled, from the feedback of the market, Movingcomm router is actually very good. According to the needs of the industry environment, based on SD-WAN+ Internet of Things, intelligent networking can then be formed into a large local area network through the cloud platform router in many places. Therefore, the focus of security monitoring can also be concentrated to complete the work of remote video surveillance, but also to meet the needs of remote working, for some of the industries we mentioned earlier, the practicality of this program is also very good. Moreover, the technology of remote networking and intelligent networking is also very mature, and the security and stability are also good. In short, the advantages of Movingcomm router are still many.
