What is Radon?
Radon is a naturally-occurring radioactive gas that comes from radioactive decay of uranium and radium deposits in soil, rocks, and well water. You cannot see it, taste it, or smell it. Radon gas atoms decay into solid radioactive atoms called “
Radon daughters” (sometimes referred to as “Radon progeny”). It is the Radon daughters in inhaled air that can deposit in our lungs and cause health problems.
Can Radon really affect my health?
YES!!! The U.S. Environmental Protection Agency (EPA) and the International Agency for Research on Cancer (IARC) confirms that radon is the leading causes of lung cancer: smoking, radon and secondhand smoke – in that order.
Where can I be exposed to Radon?
How Radon tends to accumulate in tightly-sealed homes and other buildings. The main source of high-level Radon pollution in buildings is surrounding uranium or radium-containing granite, shale, phosphate, and pitchblende. Radon enters a home through cracks in walls and foundations, basement floors, and other openings. It may also contaminate the water supply especially in groundwater (boreholes and wells).
How do I know if my home has a high level of Radon in the air?
The only way to know is to test. Testing a home is inexpensive and easy. You can contact the National Nuclear Research Institute (NNRI) , Dr. Hannah Affum or Dr. Irene Opoku-Ntim of NNRI.
Are there Areas in Ghana that have high radon levels?
Research show that some areas Ghana is said to have a major fault line stretching from the McCarthy Hill area in Accra westwards towards the Central Region and eastwards towards the Akuapim Ridge all the way to the Volta Region. The epicenter of the fault line is said to be located around the McCarthy-Weija Dam catchment area. These areas are said to be radon-prone.
What can I do if the Radon level in my house is high?
The action level recommended by WHO is 100Bq/m3 and The U.S. EPA established an action level of 4 picocuries of Radon per liter of air or 148Bq/m3. By action level, it simply means that is the level at which WHO /EPA recommends that action be taken to reduce the Radon concentration. If necessary, the level of Radon in a home can be reduced using several methods, but just ventilating a house more or using an air cleaner will greatly improve the situation.
What is normally done to seal homes better against Radon?
Radon levels can be lowered through a variety of repairs from sealing cracks in foundations, floors, and walls to changing the flow of air into the building. Sub-slab depressurization uses pipes and fans to remove Radon gas from beneath the concrete floor and foundation before it can enter the building. Radon is then vented above the roof where it safely disperses.
