Why testing matters
Radon is a naturally occurring radioactive gas that can enter a building from the soil. Any home can test high regardless of its age, foundation type or appearance, which is why measurement—not guesswork—is the useful next step.
What happens during a professional test
A testing device is placed in an appropriate location under closed-building conditions. The device collects measurements over the required period, and the results are reviewed after pickup. Occupants should avoid moving, covering or disturbing the equipment.
- Place the device in the lowest suitable level that could be occupied
- Maintain required closed-building conditions
- Keep the equipment undisturbed
- Review the measured result and recommended next step
When to schedule radon testing
Order the test when you schedule the home inspection so there is enough time for placement, measurement and retrieval before your deadline. Testing can also be useful for current homeowners who have never measured their home or after major changes to the building.
What happens if the result is elevated
An elevated result does not automatically end a purchase. Radon reduction systems are common, and a qualified mitigation contractor can evaluate the home and recommend an appropriate system. Follow-up measurement is used to verify performance.
