Stone with its quality and durability, color texture and other beautiful features of the decoration of the people of the favor, but the stone radioactive pollution hazards to health, so that people in the purchase of stone will inevitably lead to worry, this material can also be used as home improvement fashion building materials Use it?

At present, the home personalized decoration has become a general trend, natural stone with its quality and durable, color texture and other beautiful features such as popular in the random visit to several large home shopping malls, I found that all kinds of stone is widely used in Model room interior floor, table decoration.

Stone is generally low-radiation, stone hazards are mainly concentrated in the radioactive pollution. Any substance in nature contains natural radioactive elements, but different radioactive elements of different substances Bale. Stone taken from nature, containing radioactive material is positive, normal. "Whether it is natural stone or artificial stone, there will be radioactive elements exist, which is inevitable." Among them, much criticism of the stone radioactive mainly refers to the stone contains radium, thorium, potassium three kinds of radioactive elements in the decay Of radioactive material, mainly radon. "Radon is the only natural natural radioactive gas, radon in the role of the body will soon decay into the body can absorb the nuclide, into the human respiratory system caused by radiation damage, induced lung cancer.But this probability is very small in reality, Stone is generally low in radiation. "

Natural stone radioactive three categories, in 1993 the State Building Materials Bureau issued a "natural stone products radioactive protection classification control standards" on the stone was a very strict division of different levels of stone has a clear scope of application, consumers can choose stone as home improvement Material, but only in the choice of attention to the test report to see the level of identification, clear its scope.

According to the natural stone of the radioactive level, the natural stone products are divided into A, B, C three categories. Class A products can be used in any occasion, including office buildings and family rooms; Class B products are more radioactive than Class A and can not be used in interior furnishings and can be used for interior and exterior surfaces of all other buildings; Radioactive degree higher than A, B two categories, can only be used for the exterior of the building. More than C class standard control of natural stone, can only be used for seawalls, piers and monsters and other purposes. According to this classification criteria, Li Junhua remind consumers, in the choice of attention to choose a class as home decoration materials. It is understood that the State Quality and Technical Supervision has organized the State Building Materials Bureau, the 11 provinces, municipalities and autonomous regions of the 61 enterprises of 108 kinds of granite, marble and other radioactive radioactive sampling, the results of 79 kinds of qualified, With a pass rate of 73.1%. Some of the products that are favored by consumers, such as azalea, rhododendron green radioactive material is 3-5 times higher than the standard value.

Many of the physical damage caused by radioactive contamination of stone is on the one hand because the lack of basic knowledge of consumers, choose the wrong stone; but more important reason is the business caused by illegal business. Many businesses or illegal production of excessive products, or no product testing reports and certification qualifications, or create some false qualification certificate to deceive consumers, and thus illegal sales. For this problem, before buying stone, we must first enrich some common sense, not just listen to the guide to explain or just pay attention to the appearance of the beautiful. At the same time in the purchase of business requirements to provide state regulations, recognized the authority of the test report, for some civil society organizations issued a certificate to be vigilant, can not easily believe. "If these are still not too relieved, careful consumers can take some samples to the country to set the detection agencies to detect, so that the basic can be assured to buy.

There is a problem with radioactive contamination of stone. Many of the pollution in the room is caused by a single source of pollution. For radon, radon, which is radiated from ground soil, is one of the main sources of indoor radon concentration. In addition, the use of coal ash slag made of wall bricks, the radioactive material content is sometimes higher than some granite. Therefore, to remove carefully and carefully buy healthy, safe home improvement materials, "to maintain good indoor ventilation is to eliminate all the radiation material of the most simple and effective way." According to him, as long as the attention to indoor ventilation, keep the indoor air fresh, such as every morning After getting up and going down to sleep every night for half an hour to 1 hour, many pollution problems can be easily solved.
