Testing

One test canister is needed per 2,000 square feet of each foundation, and one additional test device for each additional foundation in the building. For example, if you have a basement and a crawlspace, you will want two radon test canisters - one for the basement, and one for the room above the crawlspace.
The minimum time needed to complete a radon test is 48 hours. Please note that this is test exposure time only. The test will need to be returned to the lab for analysis; consider possible transit times when mailing urgent tests.
As outlined in the Radon Test Instructions, test kits should be exposed for a period of 2 to 6 days (minimum of 48 hours to a maximum of 144 hours TO THE HOUR).
RAdata test kits received before 12 noon on any weekday will be analyzed and reported the same day they are received. Test reports are mailed out the following business day. Please note that test kits must be closed for 3 hours after the stop time before they can be analyzed by the lab.
Self-service radon test kits can only be performed by the owner of the home being tested and cannot be used for a real estate transaction.
Appointments are filled on a first-come, first-serve basis; typically, we can schedule your test within 3-5 business days of your call.
The test kit expires one year after its shipment date. If you have recently had a radon system installed, you should use the re-test as soon as practical (between 24 hours - 30 days after the installation).
It depends on the receipt date of your radon test. If the test is received on a business day prior to 12 noon, it will be analyzed and reported the same day. Please note that if a Home Inspector conducted your test, the report is provided to the Home Inspector and RAdata cannot release it directly to anyone else.
The Private Well Testing Act (or PWTA) requires a standardized test for private wells for all real estate transactions in NJ. For more information on the PWTA you can visit the NJ DEP PWTA Information page here.
The price varies depending on the test location. Visit here to look up the cost in your municipality.
The results are valid for 1 year from date of the sample; bacteria is required to be resampled after 6 months.
Turnaround times vary, typically results are available within 6 to 12 business days.
Our Radon Test Kits should be run for a minimum of two days (48 hours) and a maximum of six days (144 hours). Tests performed for less than 48 hours will be invalid due to being underexposed. Tests run for more than 144 hours will be invalid due to being overexposed.

Your results are invalid because high humidity has affected the device. The water molecules in the air attached themselves to the charcoal, leaving no room for the radon to do the same. If you have received an invalid result due to excessive weight gain, you’ll have to redo the test.

If there is visible moisture in the area, we recommend that you wait for the area to dry out first before testing. Running a dehumidifier prior to and during the test, monitoring the weather to avoid testing during days of high humidity and performing only a 2-day test is also recommended. This will lessen the likelihood of this happening again.

Test kits must be received and analyzed within 6 days of stopping the test. Example: If a test is stopped on a Wednesday at 9:00 AM, it needs to be received by us and analyzed no later than the following Tuesday at 9:00 AM. You can avoid a test being invalid for this reason by promptly mailing or dropping off your canisters after closing the test.
Our Radon Test Kits should be run for a minimum of two days (48 hours) and a maximum of six days (144 hours). Tests performed for less than 48 hours will be invalid due to being underexposed.
Our Radon Test Kits should be run for a minimum of two days (48 hours) and a maximum of six days (144 hours). Tests performed for more than 144 hours will be invalid due to being overexposed.

The chain of custody is a legal document that identifies the precise location of the test address, which is why all information must be complete and accurate. The following links are helpful in verifying that the information you have is correct and providing information that you do not have. Taking a moment to double check your information will help to avoid delays in your results due to an invalid caused by errors or omissions.

NJ Department of Treasury – Division of Taxation – You need to have the county field and street address field filled out to get results on this site. It will return all results that match.

The chain of custody is a legal document that contains the information used to issue a radon result for a specific test location. The information on the chain of custody serves several purposes. First, it identifies the test location, which must be complete and accurate to ensure that the result is issued for the correct location. Second, it provides information that is crucial to the calculation of the result. Third, it provides written proof that the test was performed by a licensed home inspector or a person who is permitted by law to perform the test. All information on the chain of custody holds the same weight of significance, therefore an invalid result will be issued for any missing or incorrect information.
