After 3 ~ 6 months, the radiation basically disappeared. Generally speaking, the radiation of ceramic tiles is very small. But for some polished tiles with good whiteness, a certain amount of zirconium silicate will be added to improve the whiteness.

Zirconium itself is not radioactive, but the zirconium ore produced by some radioactive elements cannot be separated technically, so the radioactivity of zirconium products exceeds the standard. In this case, you can ventilate more and let the air circulate.

Most tiles are fired at high temperature, and many radiation materials will lose their radiation ability at high temperature, so don't worry too much about the radiation of tiles.

Tiles:

Ceramic tile is an acid and alkali resistant ceramic or stone, building or decorative material, which is made of refractory metal oxide and semi-metal oxide through grinding, mixing, pressing, glazing and sintering. It is called a tile. Its raw materials are mostly clay and quartz sand, which are mixed by high temperature compression and other processes, with high hardness.

The history of ceramic tiles dates back to BC, and Egyptians began to decorate various types of houses with ceramic tiles. People dry or dry clay bricks, and then paint them with blue glaze extracted from copper.

In BC, tiles were also found in Mesopotamia. This kind of tile was decorated with blue and white stripes, and later more styles and colors appeared.

Integral brick is a kind of wear-resistant brick. Although there are varieties such as infiltrated integral brick, the color of integral brick is relatively inferior to glazed tile. Because interior design is more and more inclined to plain design, brick is becoming more and more fashionable. Full-body bricks are widely used in halls, aisles, outdoor walkways and other decoration projects, and are generally less used in walls, while anti-slip bricks are mostly full-body bricks.
