How to Use a Short-Term Radon Testing Device

Short-term radon measurements are valuable for capturing a snapshot of radon conditions. Short-term testing identifies potential issues or can be used post-mitigation to determine the effectiveness of mitigation. Monitoring using a short-term Radon Testing Device must be conducted for two to 10 days.

Radon Test Kits Include:

  • Rental of Radon Testing Device
  • How to Use Your Radon Testing Device Instructions
  • Sample Chain of Custody Record
  • Additional Information Form
  • Return Address Sticker and Shipping Box
  • Radon Testing Report with recommendations upon completion of lab analysis

Closed Building Conditions

When short-term testing for radon, Health Canada suggests closed building conditions are followed. These conditions should be followed 12 hours prior to starting your test.

  • Windows must be kept closed and doors opened only long enough to go in and out.
  • Exhaust fans, window air conditioners, or whole-house fans should not be operated.
  • Fireplaces (unless they are the primary heat source) must not be used and the dampers must be closed.
  • Permanent radon mitigation systems, if installed, should be functioning (on) for at least 24 hours prior to and during the measurement period. In addition, measurements of less than 4 days should not be conducted during times of severe weather.
