  • Log into your online account and go to your Radon Test Results page. Scroll to a test that is flagged as invalid and click the “Why Invalid?” link. Here you will find an explanation as to why the test is invalid and an online submission form to submit the corrections needed.

  • Why do I receive an Invalid result if my chain of custody isn’t filled out completely or has incorrect information on it?
  • 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.

  • How do I submit corrections for a chain of custody when a test is Invalid?
  • The chain of custody is a legal document and as such all amendments or corrections must be provided in writing.  Information can be provided via your online account, email or regular mail.

    Log into your online account and go to your Radon Test Results page. Scroll to a test that is flagged as invalid and click the “Why Invalid?” link.  Provide the missing or correct information in the “Correct / Missing Data” text box, provide your first and last name in their respective text boxes, and click “Submit Corrected Data.”  Once you hit submit you will be prompted to confirm your submission by clicking “OK.”  If your submission is successful you will see a flashing confirmation that message stating “Your correction has been submitted – Thank You.”

    You can email us at invalid@radata.com. Be sure to include the test address, canister ID and the corrections that need to be made.

    You can also submit your corrections in writing by mailing them to us at RAdata, 27 Ironia Rd, Flanders, NJ 07836. Be sure to include the test address, canister ID, and the corrections that need to be made.

  • Can I give one of my Radon Test Kits to another home inspector to use at his/her company?

    Please note that there is a $5.00 transfer of custody fee for each canister that is transferred before the laboratory receives the device and a $10.00 transfer of custody fee for each canister that is transferred after the laboratory receives the device (payable by either party).

  • How long are Radon Test Kits good for?
  • Your Radon Test Kits are good for one year. You will find an expiration label clearly affixed to the top of each canister. Test kits expire at the end of the month stated on the sticker. Tests need to be closed prior to the expiration date. Example: If your expiration sticker is January 2020, the test must be stopped before the end of the day on January 31, 2020.

  • How long should a radon test be run?
  • 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.

  • Why is my test Invalid due to excessive weight gain?
  • 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.

  • My test says that it’s invalid because it was received late, what does this mean?
  • 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.

  • My test says that it’s invalid because it was underexposed, what does this mean?
  • 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.

  • My test says that it’s invalid because it was overexposed, what does this mean?
  • 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.

  • Are you open on Saturday or Sunday?
  • We are open for business Monday through Friday from 8:00 AM to 5:00 PM.

  • Should I keep a copy of my chain of custody form?
  • The chain of custody contains important information about the tests you perform. We recommend that you keep a copy of the chain of custody for each property that you test for your own reference. We understand that there are times when it’s difficult to make a copy, and in this type of instance we suggest that you take a picture of it with your telephone. Keeping a copy will ensure that you have access to the property information, canister ID numbers, and test dates and times.

  • Where can I find the correct property information (municipality/city/county/zip code) for my chain of custody?
  • 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.

    Melissa Data   - Use the search box to find address.  Start typing the address and it will begin to dropdown matching properties until you find the one you are looking for.  After a certain number of searches, you must register, but it is simple and free.

    State Information Services – You need the county and street address to search in this database.

    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. If you open the result and the address shown is not the same as the address you searched it is because the owner has their mail delivered to another address. In this case, the municipality and county are correct, but you will have to use another avenue to determine correct city and zip code.

  • Can I change the test address if I make a mistake on my chain of custody?
  • When an address correction or change is requested for a report with a result that has already been issued, we are only able to make changes to the property address under certain circumstances. If both the old address and the new address exist, we are unable to change the address. 

    If a report with a result has not been issued, the address can be corrected.

  • Can I have Radon Test Kits analyzed if my license has expired?
  • In accordance with the regulations for the Certification of Radon Testers, N.J.A.C. 7:28-27.22 Renewal of Certification, if you are no longer certified you must cease all radon measurement activities.  Please note that as per this NJ regulation, any radon measurement activities conducted while you do not have a current, valid certification is a violation of N.J.S.A. 26:2D-70 et seq. (Radon Act) and its implementing regulations, and may subject you to an enforcement action, including monetary penalties.

    As of the day of your license expiration, we will remove you as a technician on our radon license as required by the NJ DEP Radon Section, and we cannot produce any radon test results for you.  If you wish to become re-certified, you must submit an initial application and fee to the NJDEP Radon Section.  If the Radon Program issues you a new certification, please send us a copy of your new license.  At that time, you will then be listed as a technician with our firm and we can begin processing radon results for you again.

    The NJ DEP Radon Section can be reached at 609-984-5425 or 800-648-0394 if you have questions on the renewal application, process, or status of your license renewal.  The NJ DEP Radon Section website is www.njradon.org .

  • My license has been renewed, why does my report say, “As per NJDEP radon regulation N.J.A.C 7:28-27.3, unlicensed person performed radon test, results invalid. Conduct another test.”?
  • As the certified measurement business, we are always required to have a valid copy of your license on file. If you renewed your license, and did not provide us with a copy, on the day of the expiration of the license we had on file we removed you as a technician on our radon license as required by the NJ DEP Radon Section, and we cannot produce any radon test results for you.

    We do send reminder notices via email notifying you that your Radon License will be expiring, as well as an email stating that you have been removed from our radon license if we haven’t received a copy of your current license.

  • How long does it take to get test results?
  • All Radon Test Kits received by 12:00 PM are analyzed on the same business day that they are received. Results are available on your home inspector portal at close of business on the day the test is analyzed.
