Numerous studies have shown that Radon gas concentrations can vary in different parts of the same City, on different streets, even different houses in the same neighborhood.  RadonFX recommends everyone test their home with a C-NRPP approved long term Radon Test.

As part of our Quality Assurance Protocols you may receive an extra test kit in your shipment or when we deploy tests.  These are duplicate tests and we ask that you place it within 4” (10cm) away from the other test device.  We send these to the lab separately then compare and track the results to ensure our test results are precise.

This depends on the layout of your home. If you have a bungalow or 2 story home you probably only need 1 test.  If you have a multi-level house or have both a basement and slab-on grade, you should consider 2 tests.

RadonFX follows Health Canada and the CNRPP/CARST protocols which specifies that mitigating should only be undertaken following a 91 Long Term Radon Gas Test.  

RadonFX uses Alpha Track Dosimeters.  These passive test devices “record” the number of Radioactive Alpha particles produced for any number of days from 91 to 365.  These are then sent to the lab for analysis where they count the number of strikes during the test period which then determines the level of Radon Gas measured in Becquerel’s per cubic meter (Bq/m3).  

RadonFX also use commercial “Continuous Radon Monitors” (CRM).  These are used before/during/after mitigation as a way to ensure that system is operating as it should.  They are also used in workplace environments to determine worker exposure.

Named after Henri Becquerel who, along with Marie Curie, won a noble prize in 1903 for their discovery of radioactivity.

A Becquerel is defined as “one radioactive decay event per second”.  

Bq/m3 is “one radioactive decay event per second in a space 1m x 1m x 1m 

If you have a level of 200 bq/m3 that means that in an area 1 meter cubed, you have 200 radioactive decay events happening every second.

While we have numerous methods to bring dangerous Radon Gas levels down to acceptable levels, the most widely used is known as “sub slab depressurization” . In a nutshell, we create a ventilation system that stops Radon from entering your house. In most cases Radon Gas levels can be brought down to less than 75 Bq/m3. (many times much less)

When RadonFX designs a mitigation system our protocol is to bring the level down the lowest level possible.

If you are reading this from Ontario, Canada, the great news is that, yes, in a way, your builder will pay to mitigate a house with high Radon levels.

First thing to note is you must have a C-NRPP certified test conducted.  Consumer Radon detectors are not acceptable.  

Once you complete a 91 day test, if your house has too high a concentration of Radon Gas, either your builder (in the first 2 years) or Tarion Warranty program (up to 7 years) will pay for the full cost of mitigation, up to $15,000.00  (typically mitigation is around $3500-$5000)

When Radon Gas decays it releases several forms of ionizing radiation.  If this happens while in your lungs the radioactive particle released can damage sensitive lung tissue, or more  accurately, the cells of lung tissue.  In some strikes the radioactive particle will kill a lung cell, which will regenerate, but others only damage a cell.  These are strikes that can cause abnormal mutations which can lead to lung cancer.

Approx 3200.  These are non smokers who developed lung cancer.  This does not include the smokers whose cancer was made worse by the ionizing radiation of Radon Gas decay.
