Natural stone, with its solemn, natural charm, has always been one of the designers like to use the materials. However, the trend of promoting environmental protection in recent years, it seems that allowing consumers prohibitive. In fact, as long as the scientific use of stone is not so terrible.
Natural stone has a certain degree of radioactivity, therefore, consumer choice, do be careful, when used to science. Below, a brief selection and use of natural stone three issues need attention.
First, the pre-selection methods and criteria to master. Stone at the level of radiation is divided into A, B, C categories, according to regulations, only the A class can be used for home decoration. Marble and granite stone are mainly two types of radiation are generally lower than marble granite, most can be used for interior decoration, and extensive use of granite should not be in the room, especially not in the bedroom, the elderly, children, the use of countertop . According to the test, put different colors of the stone of its choice of red, green or red blotches with granite varieties.
Second, the purchase invoice to sign a contract. Contracts and invoices is an important guarantee of rights, consumers should ask the seller expressly in the contract, the product name, size, grade, quantity and price, and require a clear by what standards for testing. Can ask the seller to provide the best products, proof of compliance by the legal department as the inspection reports or products of radioactive certificate. Conditions permit, it is best to test the samples for testing departments. Now, appearing on the market the so-called "international A-class", "super" in stone, some manufacturers are misleading consumers, a practice that consumers should pay attention to prevention.
Third, to be taken after the laying of diluted pollution. Harmful only 3.2 days half-life of radon, indoor radon concentration 20 minutes after the open doors and windows can be reduced to -30 minutes after the outdoor levels. Therefore, the simplest way is to enhance ventilation. Best to just renovate the room to detect substandard if the test can be used to reduce radiation lead-free paint or install shield to prevent the release of radon from building materials. If the radioactive targets too high, the stone must be replaced immediately.
