Is marble harmful to human body?

Marble is harmful to human body, and artificial marble is radioactive.

Marble, also called marble, is named for its best quality produced in Dali, Yunnan. At present, marble commonly used in the market is divided into natural and artificial.

Because natural radioactive element radium exists in natural marble, granite, gypsum and other substances, artificial marble is also filled with natural marble or granite gravel.

Therefore, when it is used as a building material for indoor decoration, the radioactive gas radon decayed from radium and its daughters will produce radiation. Radon has been listed as one of the carcinogens of 19 by the World Health Organization and the main indoor carcinogen by the International Agency for Research on Cancer.

The research shows that the indoor radon concentration in China is on the rise. The application of marble in home decoration should be minimized, and the radioactive radon concentration of marble should be detected before decoration.

We can also reduce the indoor radioactive radon concentration by replacing low radioactive stones, opening windows frequently for ventilation, using air purifiers and negative ion generators.

Extended data:

Marble pay attention to the following points:

First, go to regular businesses to buy, especially artificial marble, manufacturers must issue relevant test reports;

Second, when identifying natural and artificial marble, you can drop a few drops of dilute hydrochloric acid. The foaming phenomenon of natural marble is serious, while the foaming of artificial marble is weak, even not foaming.

The third is to identify the quality of marble, which can be tapped by hand. The sound of loose marble is low, while the sound of high-quality marble is clear when struck.
