Important Closed Building Instructions - Attn. Current Tenants and/or Homeowners

You have likely landed on this page because CNHInspections has been hired to perform a radon test in your home. In order to obtain the most accurate readings possible, and to avoid the necessity of re-testing, you are requested to adhere to the following guidelines, as required by the Nebraska Department of Health and Human Services Radon Division, to ensure that the radon monitor(s) placed in your home are not disturbed; and the conditions necessary to obtain accurate radon measurements are strictly followed for the time period requested. 

5640 N 1st HASTINGS(2).png

Please Note: Twelve hours prior to the test, all exterior windows and doors need to be closed and remain closed during the test. Normal entry and exit from the home is permitted.

​

Before the test:

  • Twelve hours prior to the test, all exterior windows and doors need to be closed and remain closed during the test. Normal entry and exit from the home is permitted.

  • If there is an active radon reduction system in this house, the radon reduction system must be operating for a period of at least 24 hours prior to beginning the test. Make sure the system is working properly and will be in operation during the entire radon test.​

 

During the Test:

  • The test must be conducted under closed-building conditions. Therefore, please keep all windows and exterior doors closed (except for normal entry and exit).

  • Please do not operate fans or other machines that bring in air from the outside. Note that small exhaust fans operating for only short periods of time, may run normally during the test. 

  • Do not operate whole-house fans.

  • You may operate the home's heating and cooling systems normally during the test. Only operate air conditioning units that recirculate interior air. For window air conditioners, operate in recirculation mode only.

  • Do not operate any type of fireplace, unless it is the primary/normal source of heat.

  • Avoid excessive operation of clothes dryers, range hoods and bathroom fans.

  • Do not disturb the test device at any time during the test. 

​​

Please be advised that if any of these guidelines are not strictly followed, the test results will be null and void, and another test at additional cost will need to be arranged and conducted in order to obtain accurate readings. 


Please note that the radon monitors placed in your home include built-in features designed to detect interference with the testing conditions, and with the testing device itself.

 

Thank you very much for adhering to these guidelines!​
