In recent years, with the increasing variety and style of ceramic tiles, ceramic tiles have been selected by consumers as an essential part of home decoration. However, the results of the State Administration for Industry and Commerce's monitoring of the radioactive dose level of tiles on the market show that some products still have excessive radiation. Expert Interpretation: Long-term inhalation of a large amount of sputum in the human body will cause changes in cells. According to Jiuzheng Building Materials Network, there are two main aspects of the radiation of ceramic tiles to consumers: internal radiation and external radiation. Radiation in the body mainly refers to the radiation of cockroaches on the human body. 氡 is a kind of radioactive natural substance, colorless and odorless, easy to spread, soluble in water, and very soluble in fat. The cockroaches emitted from the tiles are mainly derived from a chemical called radium. Radium will produce sputum after decay. After entering the human respiratory tract, some of it can still be exhaled with respiratory activity before it decays. The other part is adhered to the respiratory tract and absorbed by the body. In addition to being mainly inhaled from the respiratory tract, a few can also be The throat enters the digestive tract with swallowing action, causing radiation to the human body and destroying the human respiratory system. Because cockroaches have a high "affinity" for human body fat, if the body inhales a large amount of cockroaches for a long time, it will also affect the human nervous system, making people feel weak and drowsy. If the human body inhales a large amount of cockroaches for a long time, its radiation inside the human body will cause the cells to change, which may lead to lung cancer. γ, β rays will destroy the body's lymphocytes, reducing human immunity The external radiation of ceramic tiles on humans is mainly derived from chemical elements contained in raw materials, such as gamma and beta rays produced by decay of radium and thorium. The penetration of gamma rays is very strong. It will penetrate the human body and collide with cells in the body, which will destroy the lymphocytes of the human body, thus reducing human immunity. The β-ray has a shorter range and has a greater impact on children, but because its penetration is relatively weak, a book can block its penetration. If the tile in the home is damaged, it is best to repair it in time, because the damaged tile particles are not easily found in the food, and the broken tile powder is more likely to enter the human body through the respiratory tract, causing harm to the human body. Expert advice: do not tile in children's rooms Due to the relatively high density of cockroaches, it is usually suspended within one meter of the ground from the ground. The lower the concentration of strontium, the smaller the concentration of cockroaches. Therefore, children's rooms should not be tiled as much as possible. At the same time, because the height of the bed is generally low, people are lying on the bed, just in the strong radiation range of the cockroach, we can open more windows every day to make the air circulate and keep fresh, which can also reduce the radiation of the tile to the human body. Do not use strong acid cleaner Do not use strong acid cleaner when cleaning tiles. This will cause accelerated aging and surface chalking of the tiles, which will increase the probability of the body inhaling the tile powder and endanger human health. However, the radioactivity of the tiles will not be caused by the chemicals generated by the detergent. Increase the reaction. Among all the tiles, the ultra-white bricks in the polished tiles have stronger radiation, and the precipitation rate of radioactive elements on the surface of the glazed tiles is higher than that of ordinary bricks. If you want to choose bricks, it is best to choose matt bricks. Because radioactive materials are colorless and odorless, people in daily life can't directly discern which tiles will exceed the standard, so try not to decorate the interior with tiles. If you want to choose bricks, it is best to choose matt bricks; if you use polished tiles, usually try to open small lights in your home, try to avoid direct light or affect the eyes through reflection. So, how do consumers buy ceramic tiles? First, pay attention to their resistance to glaze cracking and strength. Good quality tiles have low water absorption. When the consumer chooses, the water droplets can be placed on the back of the tile to observe the degree of diffusion, and the water absorption is slower. The second is to pay attention to whether the surface of the tile has uneven pinholes. Tap the tile when you buy and listen to the sound. The more fragile the sound, the higher the texture density of the tile and the better the hardness. It is also possible to scratch the surface of the tile with a hard object. If a scratch occurs, it means that the glaze is insufficient. The third is to compare the color difference. If the tiles have a noticeable color difference, the effect of the decoration will be affected. Since the number of tiles purchased is large, it is necessary to compare and compare the products of each package, and observe the change of the color difference, and the color difference is generally not selectable. Tips At present, the qualification rate of ceramic tiles is basically around 90%. As long as consumers buy them from regular manufacturers, the radiation of ceramic tiles on the human body is still relatively small. In fact, the more serious is the radiation from the stone. Under normal circumstances, the radioactivity can be judged from the color of the stone. Its radioactivity is red, green, flesh red, grayish white, white and black from high to low. However, there are special cases that do not meet the above color laws. For example, "Cuckoo Green" is the stone product with the highest radioactive content.
