Radiological Analysis: RADON

Maxxam has provided analysis for radon in air for over 25 years.

Radon in Air

For rapid assessment, we recommend the short-term electret detectors. These are put in place for 2 to 5 days and allow for a rapid evaluation of the radon level.

Radionuclide Method Detection Limit
Radon-222 Electret Ion Chamber 10 Bq/cu.m

For longer term evaluation (one to six months), we recommend the “LT electret detectors” – using the same method, and with the same detection limit but over a longer time period.

Radionuclide Method Detection Limit
Radon-222 Electret Ion Chamber 10 Bq/cu.m

The Health Canada regulatory guideline for residences recommends retesting with a view to possible remedial action if the level is above 200 Becquerels per cubic metre.

Radon in Water

Radionuclide Method Detection Limit
Radon-222 Gamma Spectrometry 10 Bq/L

This analysis requires special containers for collection and appropriate sampling methods. There are also specific requirements for Ontario drinking water. Please contact the laboratory at rad@maxxam.ca before collecting water samples.

Results are reported as of the time of collection.
