who would have thought that the toilet that people can't live without every day will also cause personal injury. Recently, the quality spot check results released by the General Administration of quality supervision, inspection and Quarantine of the people's Republic of China showed that the quality of some toilets was extremely poor, and the content of radionuclides exceeded the standard. The reason is that in order to make the products look high-grade on the surface, some enterprises try their best to whiten the products, adding too many zirconium raw materials in the formula, and ignoring the characteristics of these raw materials with extremely high radionuclide content, so that the radionuclide content of the products exceeds the standard or the radionuclide content is close to the critical value

in fact, the problem of radioactive pollution of ceramic sanitary ware has not attracted people's attention today. CCTV once broadcast a news that a household in Shenyang suffered from nasal cancer due to radioactive contamination of ceramic sanitary ware used for home decoration. This news has aroused strong repercussions among consumers. Consumers have called the relevant departments to ask whether the toilets, basins, bathtubs and ceramic tiles used at home have radioactive pollution. Some consumers said that they had only heard that natural stones were radioactive before, but they didn't expect that sanitary ware was also radioactive

experts from the National Center for the supervision, inspection and testing of radioactive and hazardous substances in the building materials industry told reporters that ceramic sanitary wares such as toilets and basins are mainly made of clay, sandstone, slag or industrial waste residue, and some natural aids, which are formed and glazed by sintering. Especially on the ceramic surface “ Glaze ” It contains zirconium indium sand with high radioactivity. Although the firing temperature of ceramics is mostly 1100 ℃ -1300 ℃, the radioactivity of these substances cannot be eliminated, and its radioactivity depends on the radioactivity in the materials. Therefore, the content of radioactive substances in ceramic sanitary ware produced by various enterprises is also different. But it is certain that among all ceramic products, ultra white products in polished sanitary ware have stronger radiation performance. The emission rate of radioactive element radon on the surface of colored glaze products is higher than that of ordinary products, while the radioactivity of matte products is lower than that of polished products

the expert said that the radiation hazards in ceramic sanitary ware mainly include two aspects, namely, internal radiation and external radiation. Internal radiation mainly comes from radon and its daughters, a radioactive substance formed by the decay of radioactive radiation in the air. Radon is the only natural radioactive gas in nature. While acting on the human body, radon will quickly decay into nuclides that can be absorbed by the human body, enter the human respiratory system, cause radiation damage and induce lung cancer. Statistics show that radon has become the main cause of lung cancer. 5000-20000 people die from it in the United States every year, and about 50000 people die from lung cancer caused by radon and its daughters in China every year. In addition, radon also has a high affinity for human fat, which affects the human nervous system and makes people depressed and sleepy. Because radioactive substances are colorless and tasteless, without special instruments for measurement, people simply cannot directly distinguish which ceramic sanitary wares have excessive radiation in daily life
