LEXCheck Long-Term Radon Test Kit (Double)

2-pack of Alpha Track Detectors - perfect for larger homes or multiple rooms/floors, providing you with a higher level of confidence in the safety of your home.

This LEXCheck Test Kit contains two RSKS Alpha Track Detectors, a Canadian National Radon Proficiency Program (C-NRPP) approved radon measurement device.


Alpha Track detectors measure radon concentration by detecting the alpha particles coming from its decay process. The main component of the RSKS Alpha Track detector is the CR-39 chip that is invisibly damaged by each alpha particle. The CR-39 chip has a measuring range of 2-20,000 Bq/m3. When the Alpha Track detector is returned to our C-NRPP approved lab, the tracks on the chip are developed by an etching process. As a result, the tracks become visible and are then counted by fully automated equipment to calculate the average radon concentration of the testing location.


We offer a pack of two detectors so that two tests can be done simultaneously in houses that have more than one occupied room on the lowest level, and/or for testing rooms on multiple floors. Health Canada recommends that a radon measurement should be done in each room on the lowest lived-in level of the home that is occupied for more than 4 hours a day. Potential measurement locations include family rooms, living rooms, dens, playrooms and bedrooms on the lowest occupied level of the home. 


Long-term radon tests are recommended by Health Canada because they provide an accurate representation of annual average radon concentrations. Long-term tests are performed for a minimum of 90 days, usually during the winter when houses are sealed up and radon concentrations are at their highest. The long-term test will yield results that can be compared to the Health Canada guideline (200 Bq/m³) to determine if mitigation is recommended.


Included in the purchase of a kit:

  • Two C-NRPP approved RSKS Alpha Track Detectors.
  • Deployment and online registration instructions.
  • Laboratory analysis fees.
  • Final radon report.

The test results will be sent as a report to the email associated with your account approximately 2 weeks after the detector has been returned to our laboratory for analysis. 


Radon detectors are not refundable under any circumstances due to quality control protocol.


Pre-addressed return labels can be purchased with the test kit for an additional fee. See related products below.
