With the development of the types of ceramic tile, ceramic tile has already become an important article for people to decorate the house. However, some ceramic tiles with poor quality can cause radiation to threaten the physical health of people. It is important for people to distinguish the good or poor quality of ceramic tile and prevent the harms caused by the radiation effectively. 

The radiation of ceramic tile includes internal radiation and external radiation. The internal radiation refers to the radiation caused by to the human body. Radon is a kind of radioactive substance without color and taste. It can be dissolved in water and fat. The radon released by ceramic tile comes from a kind of chemical substance called “radium”. The disintegration of radium can produce radon. Radon can be absorbed by the respiratory tract to cause radiation inside the human body, which can destroy the respiratory tract and threaten the physical health. In addition, radon can be accumulated in the fat inside the human body. Therefore, the long-term absorption of radon can also affect the nervous system to make people depressive.

What’s more, the external radiation of ceramic radiation mainly comes from the γ ray and β ray produced by the disintegration of radium and thorium. Radium and thorium are both the chemical elements contained in the raw materials of ceramic tile. The former can penetrate into the human body to destroy the lymphocytes and decrease the human immunity. The latter has a relatively short gunshot and its radiation can be easily prevented.

People should repair the broken ceramic tiles in time, as the ceramic powders can be easily absorbed by the human body to cause serious harms. What’s more, parents should not floor the children’s room with ceramic tiles, which can decrease the harms of radiation and maintain the physical health for their children. When people are cleaning the ceramic tiles, they should not use highly acidic cleaner. The highly acidic cleaner can accelerate the aging of ceramic tiles and increase the risk of absorbing ceramic powders for the human body. People should often open the windows to maintain the ventilation so as to reduce the harms of radon. Without any professional measuring devices, people can not precisely distinguish the quality of ceramic tile. Therefore, people should not floor the whole house with ceramic tiles. In addition, compared to polished ceramic tile, honed ceramic tile is a better choice.
