Radon Detectors

Our passive radon detectors are the most accurate type used, for testing domestic, schools and commercial buildings thought England, Scotland and Wales. The detectors in our radon gas test kits should be left in place for 90 days or around 3 months. Therefore, taking into account the fluctuations in indoor radon concentrations that occur over time.
Radon gas detector kits are single-use and are simply left in the same place for the full test duration.
They are posted to our 3rd party UK Health Security Agency (UKHSA) validated laboratory for analysis. The report will be emailed to you normally within 1 to 2 working days of receiving the detectors in the lab. Please allow 5 days encase of equipment maintenance

Short Term Radon Screening Testing.

When results are required quickly or to plan mitigation throughout the whole property,  a short term screening test can be carried out.  This provides a good indication as to whether high radon concentrations are likely to be an issue. Detectors need to be left in place for a minimum of 7 days. Results are averaged over the duration of the test.

How Many detectors Do I need?

For a 3 month test, two detectors are required as a minimum.  One placed in the lounge and the second in the master bedroom.
However, if you have a large property that has been extended or a basement, then we recommend extra detectors are placed because gas can leak differently in each part of the property.
For short term testing in a small property without a basement, only one detector is necessary on the ground floor.
More detectors are advised for testing houses with basements and larger floor areas.
Public Health England state, that any domestic property measuring over 200 Bq per cubic metre requires mitigation to reduce it to safe levels.
In addition on some commercial properties, the limit is 300 Bq per cubic metre.
Following testing, we then advise on the next steps, such as whether mitigation is necessary or not.
