Are there any damage to the granite at home?
In the light-colored series of green granite, sometimes with a brightly colored green, emerald green, basket of green special minerals one day river stone. Tianhe stone itself is composed of weak radioactive yuan purple potassium, voltage, chain, and therefore contains this kind of mineral trade green granite, the radiation intensity may be too large.
Potassium-containing minerals Potash feldspar is the main component of red granite, while potassium isotope potassium-40 (40K) itself is a radioactive element. So the more potassium-containing minerals (pale pink, pink, etc.), the more likely to be strong (large). In addition, in the red granite, including gneissic granite and granite gneiss. This ancient rock, which was produced two or three billion years ago, contains not only potassium-containing feldspars, but sometimes also contains a beautiful color (purple, red, purple, etc.) special minerals - zircon (Zr A Sio4). Zircon mineral is often mixed with uranium, thorium and other radioactive elements, so that the red granite red more brilliant at the same time, then also increased the intensity of the radio, which is the famous "Indian red" and "South Africa red" roll intensity is too large (High) the reason.
Mainly granite in the white granite. Whitehead is produced in the later stages of condensation of underground turbulence, and its main component is silica (Sio2, quartz), up to 73% to 77% in rock. This stage of rock formation (ie, the later stage of magma condensation) is also the stage of the relative accumulation of uranium, thorium, rubidium, cesium, potassium and other radioactive elements in underground magma. Since the distribution of all elements (including radioactive elements) in the earth is extremely uneven, if the distribution of radiation elements in a region is relatively slightly (geologically called "background high"), then this The area of the production of white rock radiation intensity may be too large.
Granite is a good material for the building, but some areas of granite will overflow radon, radon is a natural radioactive gas, will make people suffering from lung cancer.
For the white, red, green and plaque granite in the light-colored series, it is not possible to think that the radioactive radiation intensity is large, and the radioactive radiation intensity may be too large in the following cases.
