Miss Zhang: My living room floor and the tabletop are both made of marble. I heard that marble can emit radiation—does it affect our health? Also, after some time, the floor has lots of scratches. How should I maintain it? A: Marble available in the market is generally divided into natural and artificial types. Natural marble may contain some level of radiation, and the darker the color, the higher the radiation tends to be. However, this doesn’t necessarily mean it’s highly radioactive or harmful. If you choose natural marble, look for stones that have a national environmental certification, such as Class A for indoor use. In the past, when marble was commonly used as flooring, radiation levels were more strictly controlled. Now, it's often used for countertops or decorative surfaces, and in most cases, it's safe for indoor environments. If your space is very large, make sure the room is well-ventilated to reduce any potential concerns. Artificial marble, on the other hand, doesn't emit radiation at all. It’s softer in texture and less heat-resistant, but it’s usually more durable than some natural varieties. The price is typically a bit higher, though. For maintenance, marble requires regular cleaning and protection. Since it's a porous material, it can easily absorb liquids and get stained. When cleaning, use minimal water and avoid harsh chemicals. You can wipe it with a slightly damp cloth and a mild detergent, then dry it with a clean, soft cloth. For tough stains, you can try using lemon juice or white vinegar, but be careful—leave it on for no more than 1–2 minutes. Don’t let it sit too long, as it might damage the surface. If needed, repeat the process and then rinse and dry thoroughly. For minor scratches, there are special marble cleaners and sealants available. If the marble is old, expensive, or heavily damaged, it’s best to consult a professional stone care specialist. Regular maintenance can help keep your marble looking beautiful for years to come.
