Tile radiation cancer cause exaggeration of facts can not be trusted

Since 2009, “tiles have radiation” and “tiles have caused cancer” have become popular. The AQSIQ announced the results of sampling inspections involving 8 provinces in Hebei, 272 ceramic tile manufacturers, and 364 ceramic tile products. Spot checks found that the three kinds of products "radioactive radionuclide limit" failed. Scientific research shows that long-term exposure to relatively large doses of ionizing radiation can cause discomfort to the human body. In fact, "adding a small amount of zirconium silicate into the production process of porcelain is a modern production process. It has a history of more than ten years in China and the technology is relatively mature." Senior Engineer of Ceramics and Stone Inspection Department of National Building Material Testing Center Hu Yunlin said that the radioactivity of ceramic tiles is minimal, and the amount of radiation absorbed in one year in a normal home environment is far less than an X-ray inspection, so there is no need to worry about it. In this regard, Wang Bo, the deputy secretary-general of the National Building Sanitary Ceramics Standardization Technical Committee, also stated that the radiation effects of ceramic tiles on the human body are not as great as the radiation effects caused by using a mobile phone to talk for one minute.

So, is the phenomenon of excessive addition of zirconium silicate common? Hu Yunlin pointed out that the excessive addition of zirconium silicate is generally rare. “Companies are profit-oriented, and zirconium silicate is very expensive, many small-scale production companies are reluctant to use, large enterprises control the use of zirconium silicate is very strict, there is little problem of excessive addition.” Hu Yunlin continued to explain: “ At present, China has not issued a specific standard for the use of zirconium silicate. Different production batches of zirconium silicate contain different amounts of radionuclides and are difficult to regulate.” Hu Yunlin reminds us that, in fact, we live naturally. There is a small amount of radiation in the environment itself, "does not constitute any health **", as long as the tiles are qualified for testing, you can rest assured that use.

Well-tested tiles do not interfere with health. Although "radioactivity" can always be associated with negative topics such as cancer and death, and even the discoloration of the smell, radioactivity in real life is ubiquitous. Not only is it inevitable, but it is also inevitable. Needless to avoid. Because only when the radionuclide reaches a certain amount and has long-term effects, it will be harmful to the human body. As far as radioactivity is concerned, stone and metal products are not mentioned, even though computer and cell phone supplies are far more common than ceramic tiles. So far, Foshan, Foshan, Jiangxi Jingdezhen, Hebei Tangshan and other ceramic producing areas, have not found any frontline workers because of constant exposure to ceramics and related medical cases. The workers who have been immersed in this work atmosphere for a long time are still so, let alone ordinary citizens.

Look again at the standard on which the quality inspection report is based - "Radionuclides for Construction Materials." Its limits on natural radionuclides and radioactive specific activities of radium, thorium and potassium in building materials are quite low and almost negligible compared with stone radioactive limits. The radioactive stone products can still be used in various occasions, let alone radioactive ceramics! The reason why this standard is formulated is due to the self-discipline and protection of the ceramic industry. For the moment. On the other hand, foreign countries do not only have no restrictions on relevant industry standards. On the contrary, when foreign brands encounter relevant restrictions when exporting to the Chinese market, they regard this standard as a trade barrier. In addition, relevant experts also stood up and spoke many times and considered that “the construction of sanitary ceramic products is harmful to human body” lacks medical basis.

There are alternatives but the high cost of domestic ceramic tile dispute endlessly, but the foreign ceramic industry related standards is what? Italy, St. Augustine ceramics factory representative Chen Guowei told reporters, Italy and other major ceramic producing countries in the world tile detection of radioactive There is no indicator requirement because this is the most basic requirement. For setting the radioactivity standards for ceramic tiles, we can't simply say that there is good and no, it is not good. Chen Guowei also revealed that the foreign tile inspection focuses on environmental protection, including the industrial environmental protection index in the production process and the environmental protection factor in the production process.

Since the excessive addition of zirconium silicate leads to an increase in the radioactive content, is there a high safety raw material to replace zirconium silicate? Liang Yiliu, director of the inspection office of the Guangdong Provincial Technical Supervision Quality Supervision and Inspection Station, said that high brightness whitewashing mud The same "whitening" function, but 10 times the washing mud can achieve 1 times the effect of zirconium silicate, and the refining process of washing mud is complicated, so that the cost of the tile is soaring. Therefore, he suggested that consumers should not blindly pursue whiteness when buying ceramic tiles, and try to pick yellowish and grayish ceramic tiles.

From "carcinogenic to tile" to "carcinogenic to white tiles", the topic of radioactivity on ceramic tiles has been mentioned again and again. First of all, people's lack of understanding of "radioactivity" has always had some extremely negative effects. Second, ordinary people have insufficient knowledge of ceramic tiles and the entire ceramic industry. The high degree of participation and low attention of the industry itself often results in the consequences of “good things do not go out and evil things go a long way”. What is more worrying is that not only ordinary consumers lack sufficient knowledge about the industry, knowledgeable design and sales staff are also deluded by the “white tile cancer-causing theory”. It does not even rule out the existence of interested interest groups who intentionally misrepresent the concept, mislead consumers, and use unfair competition methods to smash opponents. Therefore, in terms of enhancing social understanding and popularizing industry knowledge, both practitioners and related media can be blamed.
