Radon Testing and Measurement
Testing for radon gas in the air is important because radon is a radioactive gas that can accumulate in buildings, particularly in areas with certain geological conditions. Prolonged exposure to high levels of radon gas can increase the risk of lung cancer. Here are some options available from Canada Radon for testing for the presence of radon gas in your home:
- 2. Alpha-Track Detectors
A long-term radon alpha detector is a device designed to measure and monitor the levels of radon gas and its decay products in the environment over an extended period.
The primary mechanism for measuring radon levels is through its decay products, specifically alpha particles. When radon gas decays, it produces solid particles known as radon decay products or radon progeny. These particles are radioactive and emit alpha particles during their own decay processes. Alpha particles are relatively large and carry a positive charge, making them easily detectable and quantifiable.

- 2. Continuous Radon Monitors (CRMs)
A continuous radon monitor is a device used to measure and monitor the levels of radon gas in indoor environments over extended periods of time. Here's how a continuous radon monitor typically works:
- Detection Mechanism: The monitor employs a detection mechanism, often based on solid-state detectors or ionization chambers. These mechanisms can sense the radioactive decay of radon and its decay products.
- Sampling: The device continuously samples the air in the environment, drawing it into the monitor's detection chamber. This allows the monitor to measure the concentration of radon gas present.
- Radioactive Decay: Radon is a radioactive gas that naturally decays into other elements known as radon decay products or radon progeny. These decay products are also radioactive and contribute to the overall radiation levels in the indoor air.
- Data Collection: As the radon and its decay products are detected, the monitor records the data and calculates the radon concentration in the air. This concentration is measured in becquerels per cubic meter (Bq/m³).
- Display and Reporting: Many continuous radon monitors come equipped with display screens that show the current radon levels in real-time. Additionally, these monitors often store historical data, allowing users to track radon levels over days, weeks, or even months. Some advanced models might even have wireless connectivity, enabling remote monitoring and data reporting.
- Alarms and Notifications: For safety reasons, some monitors are equipped with alarms that go off when radon concentrations exceed certain predefined thresholds. This alerts occupants that action may be needed to mitigate radon exposure, such as improving ventilation or implementing radon reduction systems.
Continuous radon monitors are preferred in situations where accurate and ongoing radon level monitoring is required, such as in homes, schools, workplaces, and other indoor environments. By providing real-time data and historical trends, these monitors enable individuals to make informed decisions about indoor air quality and take appropriate steps to reduce radon exposure if necessary.
- 3. Well Water Radon Test Kit
A radon well water test kit is a diagnostic tool used to measure the levels of radon gas in well water. Radon is a naturally occurring radioactive gas that can dissolve into groundwater and then be released into the air when the water is used for various household purposes, such as drinking, cooking, or bathing. A radon well water test kit typically includes the following components:
- Collection Vials or Containers: These containers are used to collect water samples from your well. They are designed to seal tightly to prevent any gas from escaping during transportation.
- Instructions: Step-by-step instructions on how to collect water samples properly and safely.
- Laboratory Analysis: After collecting the water samples, you send them to a certified laboratory that specializes in radon testing. The laboratory will analyze the samples to determine the concentration of radon in your well water.
- Test Results: Once the laboratory completes the analysis, you will receive a report detailing the radon levels in your well water. This report will indicate whether the radon levels are within safe limits or if mitigation measures are necessary.
It's important to note that radon levels in well water can vary significantly from one location to another, so it's a good idea to test your well water if you live in an area where radon is known to be a concern. If elevated radon levels are detected, you may need to consider installing a radon mitigation system to reduce the risk to your health.
