Are Granite Countertops Radioactive
Granite has radiation to human body, but very faint, this part of radiation can be ignored basically.
1. Compared with other sources of radiation inside and outside the house, the radioactivity of granite countertops poses little risk to human body.In the past few years, with respect to natural granite countertops for residential use, the radioactivity of granite countertops poses little risk to the human body for other sources of radiation inside and outside the home.
2. Granite is a kind of stone with high possibility of radioactive elements, but not all granite is highly radioactive.General condition granite won't decorate material as the bedroom inside, the stone material that interior decorates is marble more, the possibility that content of its radioactivity element exceeds bid is small.
3, in fact, the stone is generally radioactive, the key to see how much radioactive element content.Test data should be the basis for scientific treatment.As long as the stone does not exceed the "building materials radionuclide limit" (gb6566-2010) standard provisions, are safe.
4. This standard divides natural facing stone into three levels according to the radiation intensity.Class A decoration materials production and marketing and use scope is not limited, can be used in any place decoration.
5. Class B decoration materials shall not be used for the interior decoration of civil buildings, but can be used for the exterior decoration of civil buildings and the interior and exterior decoration of all other buildings.
6. Class C decoration materials can only be used for the exterior decoration of buildings and other outdoor purposes, and shall be restricted from sale, that is, only used for outdoor decoration.
7, according to the test, the different colors of the stone radioactive is different, generally high dark radiation, light radiation is low.The highest are red and green, and the lowest are white and black.Accordingly, should choose red, green carefully or the granite breed that contains gules big spot.
