In recent years, with the increasing variety of tile types and styles, ceramic tile has been selected as an essential part of home decoration. However, recently, the State Administration for Industry and Commerce announced the results of monitoring the level of radioactive doses on ceramic tiles on the market. The results showed that more than 10% of the products had exceeded the standard of radiation. Where did the tile radiation come from? What kind of harm will the human body suffer from over-standard radiation? Is there a way for consumers to distinguish the quality of tiles? The expert gave the reporter a scientific answer. Expert interpretation There are two aspects of human radiation on ceramic tiles: long-term inhalation of large amounts of germanium can cause cells to change The radiation of ceramic tiles to consumers has two main aspects: radiation in the body and radiation in vitro. Radiation in the body mainly refers to the radiation of cesium to the human body. Radon is a natural material with radioactive properties, which is colorless and odorless. It has the characteristics of easy diffusion, solubility in water, and being easily soluble in fat. The cesium emitted from the tiles is mainly derived from a chemical called radium, which is contained in the raw materials of the tiles, such as slag, and zircon sand as an emulsifier (its main function is Raise the roughness and wear-resistance of ceramic tiles. Both contain radium. After decay, radium will produce helium. After entering the human respiratory tract, the phlegm may be exhaled through the respiratory activity even before it decays. The other part, which is adhered to the respiratory tract, is absorbed by the body. In addition to mainly inhaling from the respiratory tract, a few can also be The throat enters the digestive tract with swallowing movements, causing radiation in humans and damaging the human respiratory system. Zhang Qi, deputy secretary-general of the Beijing Municipal Building Decoration Association's Indoor Environment Protection Committee, also stated that because of its high affinity for human body fat, if the human body inhales a large amount of warts for a long time, it will also affect the human nervous system and make people spirit. Sluggish, drowsy. If the human body inhales a large amount of sputum for a long period of time, its radiation inside the human body will cause the cells to change, which in turn causes lung cancer. Gamma and beta rays destroy human lymphocytes and reduce human immunity The in vitro radiation of ceramic tiles on humans is mainly derived from the chemical elements contained in raw materials, such as γ and β rays generated by the decay of radium and thorium. The penetration of gamma rays is very strong, it will penetrate the body and collide with the cells in the body, will destroy the body's lymphocytes, so that people's immunity is reduced. The short range of beta rays has a greater impact on children, but because of its relatively weak penetration, a book can block its penetration. Expert advice Children's rooms do not tile Due to the relatively high density of earthworms, they are generally suspended within one meter of the ground. The lower the concentration of earthworms, the lower the concentration of earthworms. Therefore, children's rooms should not be tiled as much as possible. At the same time, because the height of the bed is generally relatively low, people lie on the bed, just within the strong radiation range of the cockroach. We can open more windows everyday to keep the air flowing and keep it fresh, which can also reduce the radiation of the ceramic tile. Do not use strong acidic cleaners Do not use strong acid cleaners when cleaning ceramic tiles. This will cause accelerated aging of the tiles and surface chalking. This will increase the chance of the human body inhaling the ceramic powder and endanger human health. However, the radioactivity of ceramic tiles will not be due to the chemistry of detergents. The reaction increased. In all the tiles, the ultra-white bricks in the polished tiles are more radiant, and the precipitation rate of the radioactive elements on the surface of the colored glazed tiles is higher than that of ordinary tiles. The best choice is matte brick Because the radioactive material is colorless and odorless, if there is no special instrument to measure, people in daily life can't directly discern which tiles will exceed the standard, so try not to decorate the interior with ceramic tiles. If you want to choose a brick, the best choice for matt bricks If you use a polished tile, usually as much as possible to open a small lamp at home, to avoid direct light or through the reflection of the eyes. How to buy In March, the State Administration for Industry and Commerce issued a circular on the monitoring of commodity quality of porcelain tiles in circulation. According to the report, according to the sample tests conducted on 79 samples sold by 75 distribution companies in 11 building materials markets in 5 cities in Guangdong, Foshan, Fuzhou, Jiangsu, Nanjing, Chengdu, Sichuan and Linyi, Shandong, 70 samples of qualified samples were found, and the radioactive dose was exceeded. Unqualified sample 9 groups, the monitoring rate of 88.6%. One is to pay attention to its crack resistance and strength. Good quality tiles have low water absorption. Consumers may drop water on the back of the tile to observe the degree of diffusion and absorb water slowly. The second is to pay attention to whether the surface of the tile has uneven pinholes. Tap the tiles when you buy, and listen for the crispness of the sound. The more brittle the sound, the higher the texture density of the tiles and the better the hardness. It is also possible to scratch the tile surface with a hard object. If scratches occur, it indicates insufficient glazing. The third is to compare color differences. If the tiles have a significant color difference, the decoration effect will be affected. Due to the large number of tiles purchased, it is necessary to compare the samples and observe the changes in the color difference. Generally, the color difference can not be selected.
