Testing should be done by a third party, therefore you may want to have a radon test done by a qualified certified radon tester instead of doing it yourself. A qualified tester can:

• Evaluate the home and recommend how to test it.
• Explain how to keep your home in the proper condition during the radon test.
• Analyze the data and provides an independent test result.

A radon tester should be able to verify that the following steps have been taken. If this is not possible, a new radon test should be performed.

• Prior to testing, occupants were notified regarding the importance of proper testing conditions, and given written instructions or information explaining directions.
• That he or she is a certified radon professional. The tester’s Certification ID number should be clearly visible on the radon report.
• The EPA recommends that radon testing be performed under closed-house conditions. This means all windows were kept closed and except for normal entry and exit, exterior doors have been shut.
• Fans or other machinery bringing air in from the outside should not be running (unless part of an existing permanent radon mitigation system). The home’s heating and cooling systems should operate normally during testing, using air conditioning units that only recirculate interior air. Evaporative coolers (such as swamp coolers) are to be off, in addition to “whole” house fans should be off.
• Closed-house conditions must be maintained for at least 12 hours before and the entire time during the testing. Test devices should not be disturbed at any time during the test.

The Nevada Division of Public and Behavioral Health recommends that all citizens test their homes with a radon device that has been shown to be proficient, to protect their family’s health. If high radon levels are found, a home should be remediated by a competent and proficient mitigation contractor.
