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.
