Why Purchase a Radon Gas Detector?

Radon gas is a natural, radioactive gas that occurs due to uranium breakdown deep within the Earth.  As the gas is created, it rises through the ground, and can enter your home through cracks in the foundation, your sump pump, pipes, or windows. 

When you’re outdoors, radon gas is dispersed by natural airflow.  However, in a home, where ventilation is variable, radon can become trapped in areas like crawl spaces and basements, and accumulate to dangerous levels over time.

Radon is odorless, colorless, and tasteless, so it is impossible to detect radon without a monitoring device.  Unfortunately, radon in high levels is extremely dangerous.  Radon poisoning is very real, and is the second-highest cause of lung cancer in the United States and Canada.

The good news is that there are various actions you can take to reduce radon accumulation in your home, including sealing your foundation or installing a radon fan.  Monitoring levels with a radon gas detector is the best way to ensure radon levels stay low, for the health of you and your family. 

It is normal for radon levels to fluctuate, so don’t be alarmed when your radon level changes slightly.  In fact, experts recommend frequent testing with a detector or detection kit, especially after action has been taken to reduce radon levels within your home.  A radon mitigation contractor can help you decide exactly what needs to be done to best protect you and your family from harmful radon gas

What Should I Consider When Purchasing a Radon Gas Detector?

There are two basic types of radon gas detectors:  active and passive.

  • Active detectors –  tend to be more expensive, but provide continuous monitoring of radon gas within the home. They typically require a power source, such as a battery set or electricity, and display both long-term and short-term radon values.  These are valuable investments for constant protection from dangerous radon levels.
  • Passive detectors – are a lower-cost option. These detectors are set up within the home for a specific period of time, then shipped to a lab, where the results are analyzed.  Some tests measure radon levels of a short period of time, such as 48 hours, while others can be placed within the home for more than 90 days to provide a long term readout. 

Once you have decided which type of radon gas detector you would like to use in your home, you’ll want to choose the best location for testing, unless you choose a portable monitor.  Since radon rises through the ground, you may wish to install the sensor in your basement.  If you do not have a basement, you can choose to place the radon detector on the first floor of your home. 

Radon accumulates in areas with less air flow, so you may choose to gather readings from the least-ventilated area in your home, or restrict ventilation during the testing period.  Always consult the user’s manual for instructions and best practices for set up, since accuracy is key when detecting radon gas. 

Frequently Asked Questions

What is a safe level of radon gas?

The ideal level of radon gas is zero.  The World Health Organization measures radon levels in Becquerels per cubic meter.  The average outdoor measurement of radon gas is between five and fifteen Becquerels per cubic meter.  If your home radon levels are above 100 Bq/m3, the World Health Organization recommends taking immediate action to mitigate the gas accumulation.

My neighbor’s house was tested for radon, and it was fine.  Do I need to test my home?

Radon is a gas created from the breakdown of uranium deep within the Earth.  It is impossible to contain it, predict it, and levels fluctuate constantly.  Though your neighbor’s house may be within the appropriate levels of radon gas, it is highly recommended every homeowner check for this poisonous gas before it harms your family.

How can I get rid of radon in my home?

The simplest step for reducing radon is ventilation.  Unfortunately, simply opening windows and running fans isn’t always cost effective, practical, or helpful for removing constantly created gas from your home.  After all, keeping windows open during a harsh winter will certainly have a negative effect on your heating bill!

Instead, there are several progressive mitigation methods you may wish to explore.  A professional radon specialist may be a great resource for determining the best course of action for your home.  This may include caulking or sealing any cracks in the foundation or basement, specialized radon fans which use suction to remove the gas from the home, or even pressurized sub-slab solutions. 

How do I know if my radon mitigation system is working?

Since radon is odorless, tasteless, and colorless, you won’t notice any changes in air quality when action is taken to reduce radon.  Therefore, it is recommended that you continue to monitor your home with a radon gas detector. 

Final Thoughts

Protecting your home from harmful radon gas levels is key for preventing radon poisoning and even lung cancer.  A radon gas detector will help you monitor these levels, giving you the opportunity to take action before you or your family become ill.
