At present, the personal decoration of homes has become a general tendency of the middle class in the city. It was originally used as natural stone in the public spaces of building facades, residential lobbies, and buildings, and began to enter the private home space. While the high-grade stone has natural patterns and beautiful colors, it can provide a wide range of creative elements. However, in daily use, many people often neglect reasonable maintenance. There are also many misunderstandings in understanding.
The material world contains almost no radioactive substances, including soil, air, water, and the human body itself. According to the experts of Stone Technology, Stone is naturally taken from nature and contains radioactive material. Stone radioactive mainly refers to the radioactive material produced by decay of radioactive elements such as radium, strontium, and potassium contained in stone, and is mainly called “氡†gas. According to the “Standard for Control of Radioactive Protection Classification of Natural Stone Products†issued by the State Bureau in 1993, currently 80% of stone samples belong to Class A stone that can be used in any occasion.
Natural stone radiation is not terrible
Will the stone cause harm to the human body? Experts explained that the radioactive level of stone is low-dose radiation and cannot and will never result in a deterministic effect soon (in the short term). "Because even if it exceeds the standard stone, the radiation emitted by the body is completely absorbed by the body, and it is also a low-dose radiation, and it may not be the culprit causing infertility, nasal cancer, laryngeal cancer." It is understood that the radiation value must be for five consecutive years. 20msv, will cause greater damage to the human body. The probability of inducing cancer with the increase in dose is generally a few hundred thousand, and is not more dangerous than taking a car or taking a train.
Good ventilation can effectively prevent radiation
Natural stone is often mistaken for the only “pollution source†in the interior and removed. In fact, the emission of ground soil is also one of the major sources of indoor radon concentrations. Therefore, the radon gas content in the basement and in the basement and semi-basement of the building is relatively high. In the case of wall bricks made from coal ash residues, The content of radioactive material is sometimes higher than some granites. There are also coatings used in interior decoration, and the release of formaldehyde and benzenes are also harmful to the human body. In addition, a small amount of micro-radiation will be released like televisions, refrigerators, computers, air conditioners, and microwave ovens.
Good ventilation can effectively prevent radiation
“Maintaining good indoor ventilation is the easiest and most effective way to eliminate all radioactive substances.†In the interview, experts said that if you do not understand the status of radioactive materials contained in natural stone, or accidentally misuse “B type†stone (can be used to remove room) Interior and exterior finishes of all buildings other than the interior trim are refurbished in the family room and do not have to be panicked. According to him, as long as you pay attention to indoor ventilation and keep the indoor air fresh, such as every day after getting up early in the morning and every night before going to sleep to open the window for half an hour to one hour, many pollution problems can be easily resolved.
Myth: Judging the size of radioactive material by color
Many people believe that light-colored stone is more radioactive than dark-colored stone. Actually, this is not absolute. The radioactivity of many dark-colored stones (such as red) is not higher than the standard specified in Class A, and is lower than some light-colored stones. In fact, the source of stone radiation is mainly related to the magma formation process, which is related to the mine from which it was taken. It is related to its chemical composition, and it has no direct relationship with its color. Marbles, most slabstones, dark series (including black, blue and dark green), and gray series of granites have low radioactivity and can be identified as "A" products even if they are not tested.
