There are two main aspects of radioactive hazards: in vivo radiation and extracorporeal radiation. In vivo radiation mainly comes from the radioactive substance strontium and its daughters formed by the decay of radioactive radiation in the air. Earthworm is the only natural radioactive gas in nature. It acts on the human body and quickly decays into a nuclides that the body can absorb. It enters the human respiratory system and causes radiation damage, which induces lung cancer.
In addition, cockroaches also have a high affinity for human body fat, which affects the human nervous system, making people feel uncomfortable and drowsy; external radiation mainly refers to the direct irradiation of the body in the natural stone (stone decoration effect diagram) It produces a biological effect that causes damage to the blood-forming organs, nervous system, reproductive system and digestive system in the human body. 1. Beta and gamma rays can destroy human lymphocytes and reduce human immunity.
1. 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.
2. The β-ray has a shorter range and has a greater impact on children, but because of its relatively weak penetrating power, a book can block its penetration.
3. 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.
Second, there are two main aspects of the radiation of ceramic tiles to consumers: internal radiation and external radiation.
1. In vivo radiation mainly refers to the radiation of cockroaches on the human body. æ°¡ is a kind of radioactive natural substance, colorless and odorless, easy to spread, soluble in water, and very soluble in fat.
2. The enamel 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 The role is to improve the smoothness and wear resistance of the tiles.
