Radon Testing and Quality Control
Radon, a Class A carcinogen, has been proven to cause lung cancer when exposed to elevated levels over a prolonged period of time. The only way to know if levels are elevated is to test using an EPA approved test device. The devices used for a short term test is typically some type of passive charcoal canister or active Continuous Radon Monitor. How do you know if the devices used to test for radon are accurate?
Professional radon measurement providers are required to have a QAP (quality assurance plan) in place to monitor accuracy. This includes use of Continuous Radon Monitor (CRM) accuracy and charcoal canisters. . This Quality Control cross check should be done after every 10 radon tests are performed. The cross check can be done with 2 CRM’s or it can be done with one CRM and a passive charcoal canister.
Since the lab performs the analysis for charcoal canisters, the lab will have their own quality control process for checking batches of canisters prior to release for use. A professional can also cross check a batch of canisters with a CRM.
Professional radon measurement providers are required to have their CRM’s calibrated annually. Pros also go through a recertification process every two years by sending their CRM to a radioactive chamber followed by analyzing the results. Pros also have continuing education requirements to meet updated standards.
Testing your home for radon gas can be done by a professional or by purchasing an approved EPA home kit. Make sure to follow all directions carefully when testing on your own and check the test kits expiration date. If any questions arise, reach out to a pro…your health and your family’s health depends on it.
