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:


1.     Alpha-Track Detectors

These devices contain a piece of plastic that is sensitive to alpha particles emitted by radon and its decay products. The plastic darkens as it is exposed to radiation. The detectors are placed in the test area for a designated period (usually 3 months) and then returned to a lab for analysis.


2.     Continuous Radon Monitors (CRMs)

These electronic devices provide real-time measurements of radon levels. They measure radon levels hourly or at shorter intervals. CRMs are more expensive than passive methods but offer immediate results.


3.     Well Water Radon Test Kit

A radon well water test kit is a specialized tool used to measure the concentration ofradon gas in well water. Radon is a naturally occurring radioactive gas that can dissolve into groundwater and potentially pose health risks when it is released into the air during water use, such as showering or doing dishes.


After testing, if radon levels are found to be above recommended guidelines (usually 200 Bq/m3 in Canada), mitigation measures should be considered. Radon mitigation techniques can include improving ventilation, sealing cracks in the foundation, installing a radon mitigation system, and more.
