[ Chinese wardrobe net ] When it comes to decoration pollution, everyone will think of formaldehyde pollution and benzene pollution. In fact, we also need to prevent another type of pollution - æ°¡ pollution. Radon is a radioactive substance that attaches to inhalable particles and enters the body through the respiratory tract, causing damage to the respiratory system.æ°¡ is one of the environmental carcinogens recognized by the World Health Organization and is recognized as the second largest cause of lung cancer other than smoking. Its health hazard is also manifested in the lack of energy and fatigue. Compared with formaldehyde and benzene, the colorless and odorless property makes it difficult for residents to detect its existence. It can only be found by detection. The cockroaches in the living room are mainly from stone building materials and rocky soil under the base of the house. As a result, rooms with cracked walls, rooms with large amounts of rock-like decorations, and rooms with low floors (bathrooms and basements, semi-basements) have a relatively high radon content. To prevent and reduce the hazards of cockroaches, the following should be done: 1. Minimize the use of rock-like decorative materials and reduce the possibility of sputum contamination from the source. 2. Purchase stone and other decorative materials that have been radioactively tested and meet national standards. 3. Apply varnish or other materials to the cracks in the wall to prevent the spread of cockroaches by physical isolation. 4. Frequently open windows to ventilate the pollutants to the outside. Experiments have shown that opening the window for 1 hour can reduce the strontium content to about 30%.
