Radiation is the most harmful factor of building materials to people because the radiation comes from abnormal radioactive elements. The existing home decoration stones are granite, composed of quartz, feldspar and mica, and the other is marble. These two kinds of stone contain some radioactive elements, such as radium, uranium, etc. These elements will produce radioactive substances such as radon during the decay process. Long-term breathing of high-concentration air containing radioactive substances will cause radiation damage to the human respiratory system, especially the lungs, and cause a variety of diseases, such as chest pain and fever. In severe cases, it can also lead to cancerous changes in some human cells, which is life-threatening. . In addition, ceramic sanitary wares used in building decoration may contain excessive amounts of radioactive materials, which may have adverse effects on human health.
