Are tiles harmful to the human body?

Ceramic tiles are available in every household. With the development of society, the types of ceramic tiles have gradually become more diverse. Now more and more people are wondering whether ceramic tiles are harmful to the human body. In fact, experts believe that some ceramic tiles are indeed harmful to the human body, and the most common harm is radiation. So how does ceramic tile radiation cause harm to the human body? Let's learn about it together below.

Internal radiation mainly refers to the radiation of radon to the human body. Radon is a natural radioactive substance that is colorless and odorless. It is easily diffusible, soluble in water, and extremely soluble in fat. The radon emitted from tiles mainly comes from a chemical substance called radium, which is contained in the raw materials of tiles, such as slag, and zircon sand used as an emulsifier (the main function of which is to improve the smoothness and wear resistance of tiles).

When radium decays to produce radon, after radon enters the human respiratory tract, before it decays, part of it can be exhaled out of the body with breathing activities, while the other part adheres to the respiratory tract and is absorbed by the body. In addition to being inhaled mainly from the respiratory tract, a small amount can also enter the digestive tract through the throat with swallowing movements, causing radiation to the human body and damaging the human respiratory system. Because radon has a high "affinity" for human fat, if the human body inhales large amounts of radon for a long time, it will also affect the human nervous system, making people lack energy and drowsiness. If the human body inhales large amounts of radon for a long time, the radiation inside the body will cause cells to mutate, leading to lung cancer.

The external radiation of ceramic tiles to humans mainly comes from the gamma and beta rays produced by the decay of radium, thorium and other elements contained in the raw materials. Gamma and beta rays can destroy human lymphocytes and reduce human immunity. The penetrating power of gamma rays is so strong that they can penetrate the human body and collide with cells in the body, destroying the body's lymphocytes and reducing the person's immunity. The range of beta rays is shorter and their impact on children is greater, but because their penetrating power is relatively weak, a book can block their penetrating power.

If there are broken tiles in your home, it is best to repair them in time, because the particles of broken tiles fall into food and are not easy to be found, and the powder of broken tiles can more easily enter the human body through the respiratory tract and cause harm to the body.
