In some countries, radon gas is the second leading cause of lung cancer etiology. According to the average level of radon gas in the country, there are 3-14% of lung cancer caused by radon gas. Radon gas is more likely to make smokers into lung cancer, in addition to the main cause of lung cancer in nonsmokers. Radon gas forcing lung cancer at low concentrations, are not at high concentrations, because there is a low concentration of indoor radon gas in contact with many people at home. Home radon gas concentration is low, the risk is also smaller.
What is The Radon Gas?
Radon gas is a naturally occurring radioactive noble gas, it colorless, tasteless, odorless. It produces radioactive natural uranium found in rocks and soil. Radon gas can also be found in the water.
Easy radon gas out of the ground and released into the air by decay of short-lived radon-called sub-nuclear radon or radon decomposition. Gas sub-nuclear radon or radon emits radioactive alpha particles, these particles can be attached to the aerosol in the air, dust and other particles. When we breathe, sub-nuclear radon can be deposited on the cells lining the airways, while the alpha particles can damage the DNA and potentially cause lung cancer.
Radon gas in the home
For most people, most of the contact with radon gas from the house. The concentration of radon gas in the home depends on:
- Fill uranium from rocks and soil
- The entry of radon gas on the way home
- Exchange of indoor air and outdoor, it depends on the construction of the house, ventilation habits of the inhabitants and closing a window
Radon gas into the home through:
- Cracks in the cement floor and between walls
- Gaps in the floor
- A small hole in the wall
- Septic tanks and sewers
- Radon levels are usually higher in basements, warehouses basements or other structures in contact with soil zone
Reduce radon gas in the home
Available through the following methods to reduce the levels of radon gas in the house:
- Increase of ventilation
- Avoid gas radon from the basement into the living room
- Increased ventilation under the floor
- Installing a radon gas storage system in the basement
- Close the floor and wall
- Installation of positive pressure ventilation or positive supply systems
In new home construction, especially areas with high radon gas, it is necessary to consider safety. In Europe and the United States, including protective measures in new buildings has become routine, and in some countries has become a mandatory procedure. Passive radon gas mitigation systems have been shown to reduce levels of indoor radon gas up to 50%. When adding the vent radon, can further reduce the level of radon gas.
