A passive monitoring and measurement device incorporates a polymer film that is sensitive to radon gas. The presence of radon gas progressively changes the composition of the film. Laboratory analysis techniques measure any changes and determine the level of gas present.
Measurements are usually taken in the most widely used rooms of a dwelling – the lounge and bedrooms for example.
Radon levels in a building can vary significantly over time due to local weather conditions and seasonal changes and so tests run over several months deliver the most accurate results. A standard test should cover at least a three month period. Fast track services are offered if assessments are urgently required; for example for a surveyor’s report as part of a house purchase process.
Airtech offer a 10 day rapid review service or a 90 day comprehensive test.
Our radon gas detection kits contain two pods which are small and unobtrusive. They’re easy to use and come with full instructions on placement. Usually one is placed in the lounge and the other in a bedroom. After 10 days or 3 months remove your gas detection pods, complete the form included with the kit and return it with the detectors directly to the independent laboratory for analysis using the pre-addressed and postage paid envelope provided.
You should receive your test results within a couple of weeks. If your radon levels are reported to be above the government recommended Action level of 200 Bq m3 you should consider taking remediation measures.
