Choosing the Room to Test
The test should be done in the lowest lived-in level of your home. This means an area that people are in at least 4 hours per day. For some, this may be a basement with a family room, play room, or basement bedroom. For others, it will be the ground level floor.
Placing the Radon Test kit
For best results, the test kit should be away from walls, ceilings, and other large objects that would prevent good air flow around the kit. It should be at least 16 inches (30 cm) from interior walls and 20 inches (50 cm) from exterior walls and the ceiling. It should be 3 feet to 6.5 feet (0.8 m – 2 m) from the floor, at the height of a normal breathing zone. Examples of where to place the kit are on table or on top of a dresser. You can also hang the test kit from the ceiling on a 20 inch string or strap. You can attach the string or strap to the test kit with a piece of stick tack or tape.
Do NOT place the test kit:
- On the floor
- In a kitchen or bathroom
- In a crawl space, closet, or cupboard
- Near a sump pump
- In direct sunlight
- Near heat sources such as stoves or fireplaces
- In drafty areas or near vents
- In a laundry room or furnace room
- Near electrical appliances
- Directly next to anything that would prevent good air flow around the test kit. For example, do not place the kit right next to a stack of books or a standing picture frame.
