Assessment is the only way for you to know the radon level at home.
As human body will not develop immediate symptoms against radon and generally health problems will only appear gradually after a few years, US Environmental Protection Agency, American Lung Association and American Medical Association, etc recommend citizens to measure the radon level at home. |
| |
| After assessment, if the radon concentration at home is higher than the acceptable level (4 pCi/l), improvement projects are needed to protect health. |
|
| As the main sources of indoor radon can be different, we need different solutions to reduce the indoor radon concentration. |

1.Source: Rock (soil) under the base
Solution: Install ventilation system specially designed for radon to the buildings
The ventilation system specially designed for radon is composed of fans and pipelines. It can absorb radon in the soil and then release it at the level higher than the building in order to let outdoor air dilute the radon. This can prevent radon from entering and accumulate at home. This method is particularly suitable for low-rise structures with less than 3 storeys. |

2.Source: Indoor construction materials (e.g. granite or ceramic tiles)
Solution: Paint the floor, wall and ceiling with anti-radon latex paint
After using the anti-radon latex paint, the surface of the floor, wall and ceiling will form a layer of protective coating, which provides effective sealing to prevent radon from entering into the home through cracks and gaps. This method mainly targets at radon produced by indoor construction materials. Therefore, this is suitable for any types of buildings.
