Radon gas is a naturally occurring Class 1 carcinogen and the second leading cause of lung cancer, immediately behind cigarette smoking. An odorless and colorless gas, radon can only be detected by detectors designed to react with and record radon activity. Levels in a home, workplace or school will vary based on many factors including composition of the ground beneath the home, foundation age and types, and ventilation throughout the tested environment.
Being there is no definitive set of contributing factors that will yield a high or low indoor radon level, the Environmental Protection Agency, Health Canada, and the World Health Organization agree that ALL homes be tested for radon. For more information, visit our About Radon page.
The first step in assuring a healthy indoor environment is to perform a radon test. Circumstances usually dictate what kind of test, length of test, and frequency of testing should be performed and these are some general practices.
Short-term tests, like Radonova’s Rapidos detector, are performed over the course of a few days, with the Rapidos needing at least 10 days. A great preliminary test, short-term tests will allow you to see an immediate radon level in the home and make an early determination if an extremely high level needs to be fixed or if a borderline result needs additional testing. For workplaces and schools, the Rapidos allows for an easy deployment and retrieval schedule that can fit nicely within the site’s business hours and company work schedules eliminating unit loss and the need for redeployment due to over exposure.
Long-term tests, like Radonova’s Radtrak2, will be performed for at least 90 days and up to 1 year. Collecting a years’ worth of data will yield a result directly compareable to the 4.0 pCi/l (200 Bq/m3) yearly exposure guideline. Whether testing a home after getting a borderline short-term result or performing yearly follow-up tests after installing a mitigation system, a long-term test is ideal. In workplaces and schools, long-term tests are acceptable but due to longer exposure times, not always recommended. Schools typically have long periods when the buildings are not occupied, and workplaces want quick results when levels can potentially affect hundreds of thousands of workers.
Even if you have tested for radon before, contributing factors to higher and lower radon levels are always changing. It is advised that a radon test be performed every two years on a home or building that initially had a radon level below the guideline. Homes or buildings that have been fixed due to an initially high level, should be tested once a year to ensure that remediation efforts performed continue to keep radon levels below the guideline. Many states have other testing requirements for homes and buildings and should be consulted before starting any major radon project.
