Then, household personalized adornment become a common trend, natural stone material with its qualitative strong and durable, color texture characteristics such as elegant has favored in random visit several large household in the mall, the author found that all kinds of stone material is widely used in example room decorate indoor floor, mesa. But news reported shortly before a young man for family stone radioactivity pollution cause infertility, let people in the news of choose and buy when can't help produce some stone worries, the home installs stone whether he can use? Suffer the stone material of radioactive pollution for how serious, how to choose to a safe home outfit stone?
Stone radiation strong look at certificate, stone material choose and buy low radiation overall belong to
These appearance elegant stone material harm how? The author interviewed at renmin university of China environment institute of anonymity, professor, in his view, the stone material harm on mainly concentrated in radioactive pollution. According to his nature in any material introduced contain natural radioactive elements, only different substances content of radioactive elements differ. Stone back to nature, containing radioactive substances is affirmative, normal. "Whether natural stone material or artificial stone, there'll be radioactive elements exist, this is inevitable."
Among them, the stone material of training-camp radioactive has mainly refers to the stone contained radium, thorium, potassium three radioactive elements in the decay of radioactive material, produced mainly for radon. "Radon is the only natural radioactive gas nature in effect at human body, radon and will soon absorbed nuclide decay adult fitness, enter the respiratory system cause the radiation damage, induce lung cancer. But this one chance in reality is small, stone material belongs generally to low radiation." Environment, professor with the school of said.
Natural stone material radioactive divided into three types
According to the natural stone radioactivity level, the natural stone products into A, B and C three types. A kind of product can be used on any occasion, including office buildings and domestic bedroom; B products than A kind of radioactive degree, not used for bedroom interior surface, can be used for all other inside and outside of the building facing; C products radioactive level higher than A, B two kinds, the only for building surface decoration. More than C standard components of natural stone material, only for seawall, pier and stones and other purposes. According to the classification standard, LiJunHua warns customer, when the choice to pay attention to choose A kind as home decoration materials.
According to understand, the national quality technology supervision bureau of national building was organization, the national 11 provinces, municipalities, autonomous regions of the 108 kind of 61 companies such as granite, marble stone radioactive conducted sampling inspection, the results 79 qualified, nine overweight, percent of pass is 73.1%. Some of them were consumer favourite products, such as cuckoo red, cuckoo green radioactive substances have higher than standard 3-5 times.
The choose and buy stone to see the test report
Since stone have clear level limit applicable range and in real life, why there are still for stone radioactive pollution and cause a harm to human body, the event this, Beijing industry and commerce college chemistry and environmental engineering college professor noted that consumers QianFeng lack the basic stone material management and operation business, choose common sense is not standard are important reasons.
The author in visit several large domestic outfit bazaar, random observed some consumers buying behavior, few of them possess professional stone material choose and buy is listening, basic knowledge of stone, and guide explain the choice also stay in surface texture, color, only a few on issues such as consumers would mention radiation problems.
In addition, the author in visit when he noticed that, most of the stone salesman lack of expertise is difficult to answer such as stone "species" "level" key information, when the author require companies to provide product inspection report or relevant certification, many salespeople both expressed their products without a problem, but refused to or with all sorts of reason avoid show.
Consumers in the choose and buy, must first stone before full some common sense, just listen to the interpretation of the gentlemen only paying attention to appearance or beautiful. And when the choose and buy require companies to provide state regulations, approved authority detects report, for some civil society organization issued certificate to want vigilant and not easily believe. If for these still don't too relieved, conscientious consumers can also take some samples to countries set inspection institutions, such basic can trust to purchase.
In addition, remove carefully choose healthy, safe home outfit, materials, the "keep indoor and ventilated good all the radioactive substances is to eliminate the most simple and effective methods. Just note indoor and ventilated, maintain indoor air fresh, like every morning wake up and before I go to sleep at night every window half an hour to an hour, many pollution problems can be solved easily.
