In recent years, marble tiles have been selling well, and whether they are radiated like natural marble has also attracted people's attention. Recently, CCTV2 "Is it true?" program through unannounced visits, actual measurements, prove that marble tiles have radiation, but the standard marble tile use is not limited.
Marble tiles are popular in the market due to factors such as the high-end atmosphere of marble. However, there are doubts about whether consumers have radiation on marble tiles. Marble tiles do have radiation
In order to verify the authenticity of the "marble tile radiation harm to health", CCTV Financial Channel "Is it true?" column group visited the large building materials market in Beijing, and visited a well-known marble tile franchise store in Foshan and several other brand stores. .
In the program, Zhu Li, executive deputy director of the Radiation Protection Office of Tsinghua University and Ph.D. in geochemistry, used professional instruments to conduct on-site inspection of the emission values ​​of marble tiles. The test results showed that the sample of the three products sampled caused a change in the indoor emission value.
However, Professor Zhu Li pointed out at the scene that the samples tested belong to Class A building materials and can be used safely. According to reports, the country's current building materials standards, strict control of radioactive control standards, divided into three levels A, B, C. The emission value is as follows in the construction materials of category A, and the scope of use is not limited and is applicable to any place.
Professor Zhu said that the degree of radiation of natural marble has a lot to do with color, but the degree of radiation of marble tiles is not directly related to color.
Ventilation eliminates radiation pollution
Marble tiles are not completely non-radiative. Pay attention to indoor ventilation and keep indoor air fresh, which has a certain effect on reducing radiation.
Taking radioactive radon gas which is harmful to the human body as an example, the actual test shows that: in a room where the door and window are completely closed for one night, the radon content in the living room has reached 151 Baker per square meter, and after one hour of ventilation through the window. The content of bismuth dropped to 49 Baker, which is in full compliance with the standard.
It can be seen that the most effective way to eliminate indoor radioactive radiation and other pollution is to strengthen indoor ventilation. After getting up every day, open the window for 30~60 minutes, so that the dirty air accumulated in the night and the fresh outdoor air can be fully circulated to ensure that the indoor air is fresh during the day and falls asleep every night. The window is still open for 30~60 minutes to ensure that the whole family sleeps comfortably and safely at night.
