New construction property radon testing must be performed at the appropriate time for it be a valid test. Many properties when under construction are contracted before the home is completed. Nearing the end of construction coming up to closing can present a rather frenetic time for the developer to get everything completed. Trades people are going in and out of the structure finalizing installations. That being said, when should the radon testing be performed in new construction real estate?
Radon testing should NOT be done when every trades person on the job is scurrying in and out of the property to get their work completed. When the trades people have completed their work and the house is quiet waiting for final inspections is the best time. This way, “closed house conditions” can be maintained and activity is at a minimum.
Recently, I was asked to perform an electronic radon test in a home that was under pressure to finalize the basic installations. At the time of deployment, information was shared that no one would be entering the basement for the 48 hours required for a short term test and there would be minimal activity in and out of the house. The house conditions were acceptable at the time of setup however when I returned to collect the Continuous Radon Monitor, the doors were opened every 5 minutes, the basement door was closed but the basement was covered in dust and the radon machine was moved multiple times. In situations like this, the test may be invalidated as the proper conditions were not in place. The health of the new home owners is at stake if the radon test is not performed properly resulting in skewed levels.
Test Your Home, School and Workplace…Protect Your Family, Employee and Yourself!
Your home has a radon mitigation system installed because your radon levels were elevated and you chose to create a safe internal environment for your family. You are going on a family vacation for the winter school break and are unplugging or turning off your computer and some other devices to save electricity.
Should you turn off your radon mitigation system while you are away? Will you save money on electricity? The only one home is the cat after all!
The amount of power or electricity used to maintain a radon mitigation system running properly is minimal. These systems are designed to run constantly and the fan installed is actively pulling the radon from under the slab to keep levels low. That is why radon testing is recommended every 2+/- years; To make sure the fan is working properly over a long term basis.
Without the fan running, radon will build back up again very quickly. When you return home from your vacation after your home has been closed up, the radon levels will be elevated. It is recommended you leave your radon mitigation system running while you are away for vacation and come back home to safe internal environment.
Radon, an insidious Class A carcinogen, has been proven to cause lung cancer with long term exposure. AARST-NRPP is the United States of America’s professional radon organization working to save lives.
American Association of Radon Scientists and Technologist (AARST) is a professional organization that is dedicated to delivering outstanding service, the highest standards of excellence in addition to the ethical performance of radon measurement, radon mitigation and transfer of technical knowledge through superior and continued education. AARST is a not for profit trade organization.
National Radon Proficiency Program (NRPP) is the section of AARST that assists Radon Measurement Providers also known as Radon Testers re-certify their credentials every 2 years to maintain their active status. This requires taking continuing education courses to stay current with industry changes and advancements in addition to device recertification. The recertification process for analytical devices requires the Radon Measurement Provider to ship their analytical device (aka electronic method of radon testing using a CRM or Continuous Radon Monitor) to a radioactive chamber to be loaded with radon alpha particles. The chamber then returns the technician’s loaded analytical device back to them. The technician then performs the data analysis of the loaded device. The results are sent to the chamber lab and if all matches correctly from the test, the technician is re-certified once all continuing educational requirements are met.
Without re-certification, the Radon Measurement Provider cannot perform radon testing using an active device. Please watch the informational video below about why it is so important to test your home for radioactive radon gas today.
