Tile radiation does exist
First of all, the raw materials of the ceramic tile are mineral powder such as stone powder, quartz powder, long sand powder, zircon powder, etc., which emit a special kind of radiation during the metamorphosis process, thereby generating radiation.
Secondly, in order to make the tiles more beautiful, various materials are added in the processing, such as glazed tiles, which are applied with a layer of glaze on the tile base. Most of these glazes are from potassium-containing minerals such as feldspar, mica, etc. These minerals contain certain radioactive materials such as uranium and potassium.
Low tile radiation
Generally, there are traces of radioactive radiation in ceramic tiles, but the radiation of generally qualified ceramic tile products is controllable within the safety range allowed by the state.
Although tile radiation is inevitable, there is no need to panic too much, because qualified tiles are basically harmless to human health. Related experts said that the radiation effect of ceramic tiles on the human body is not as great as the radiation generated by talking on the mobile phone for one minute.
In addition, consumers should pay attention to the selection of a class standard products when purchasing home-made ceramic tiles. In the course of use, it is also necessary to arrange the paving position reasonably, paying attention to ventilation and ventilation.
National regulations on the degree of radiation of ceramic tiles
The standard of excessive radiation of ceramic tiles, this kind can not be used for interior decoration. The radioactive products of ceramic tiles are not measured by simple pass or fail, but are divided into three categories: a, b and c:
a. The level of radioactivity is the lowest, and its production, sales and use range are not limited.
b. Classes are not applicable to the interior finishes of Class I civil buildings such as houses, hospitals, schools, etc., but can be used for the exterior finishes of Class I civil buildings and the interior and exterior finishes of all other buildings.
c. Classes can only be used for exterior finishes of buildings and for outdoor use.
How to reduce the radiation hazard of tiles in life
1. It is best not to lay tiles in children's rooms: the density of cockroaches is large, and it is usually suspended within one meter of the ground from the ground. The lower the concentration of cockroaches, the greater the concentration of cockroaches. Therefore, children's rooms should not be tiled as much as possible.
2. It is best to choose matt bricks: try not to decorate the interior with tiles when decorating. If you want to choose bricks, it is best to choose matt bricks.
3. Select tiles that meet the Class A criteria: When purchasing tiles, it is best to note whether the package indicates that the product meets Class A criteria.
4. Buy ultra-white bricks to be wary of excessive zirconium silicate: In the production process, in order to achieve the effect of whitening, the amount of zirconium silicate will be added in an appropriate amount, while some enterprises add excessive amounts of ultra-white bricks, which may lead to excessive radiation of ceramic tiles. .
5. If polished tiles are used, usually try to open small lights at home, try to avoid direct light or affect the eyes through reflection.
6. Daily windows should be opened more to allow air to circulate and keep fresh, which can reduce the radiation of tiles on the human body.
7. Do not use strong acid cleaner: although the radioactivity of the tile will not increase due to the chemical reaction generated by the detergent, if the tile is cleaned with a strong acid cleaner, it will cause accelerated aging of the tile and surface powder, increasing the human body. The chance of inhaling ceramic tile powder is harmful to health.
8. After the tile is damaged, it should be repaired in time: the damaged tile particles are not easy to be found when they fall into the food, and the damaged tile powder is more likely to enter the human body through the respiratory tract, causing harm to the human body.
What are the common radiation items in life?
The widespread use of household appliances, while bringing convenience to people's lives, the electromagnetic radiation generated by them is also a potential threat to human health.
Microwave oven, hair dryer, TV, computer, refrigerator, air conditioner, electric blanket, mobile phone, washing machine, electric iron, humidifier, rice cooker, etc.
In general, the radiation of microwave ovens is among the highest in home appliances. Microwave radiation can disturb the central nervous system, causing headaches, dizziness, memory loss, insomnia and other symptoms.
Do not look directly at half a meter away from use, especially pregnant women should pay more attention.
The use of very high frequency mobile phones, the radiation intensity is also very large. When using it in daily use, you should try to make a long story short, and then get it to your ear and answer it. It is recommended to use headphones.
The smaller hair dryer is the "radiation king", especially when it is turned on and off. And the greater the power, the greater the radiation. When the hair dryer is used close to the head, it can cause central nervous system dysfunction, leading to sub-health symptoms such as dizziness, fatigue, memory loss, loss of appetite, insomnia, and forgetfulness. The correct method should be used when using it. For example, when turning on and off the hair dryer, try to stay away from the head as much as possible. Do not use it for a long time.
The back and side of the desktop computer have a large radiation, so it is best not to open the case. The laptop is concentrated on the top of the keyboard, preferably using an external keyboard. LCD TVs and plasma TVs, although much smaller than traditional old-fashioned TVs, still have some hidden dangers. It is recommended to watch TV at least 1 meter away from the TV.
