Frequently Asked Questions

Radon

What is radon?

Radon is a radioactive gas that forms when the Uranium in natural stone decays. The gas decays into radon progeny which are radioactive metal atoms that get caught in our respiratory tracts during inhalation. Radiation emitted from the radon progeny causes lung cancer by damaging the cells in our respiratory tracts and lungs. For additional information visit our About Radon page.

Does radon smell?

Radon gas is odorless and a test is the only way to detect the gas. The amount of radon in indoor air will vary depending on structural deficiencies, ventilation, and is influenced by the weather outside. Due to these factors, it is recommended that all dwellings, schools, and workplaces be tested for radon gas.

How dangerous is radon in indoor air?

World Health Organization (WHO) states it is proven that radon, a Group 1 carcinogen, can cause cancer. Radon is the second leading cause of lung cancer after smoking and is estimated to cause 22,000 deaths a year. Lung cancer kills more people than breast, pancreatic, colorectal, and prostate cancer COMBINED.

Testing

What kinds of tests are there for radon?

Radonova offers two alpha track detectors, the Radtrak² and the Rapidos.

The Radtrak² is a long-term test that will monitor between 90 days and 1 full year. The guidelines put in place by the EPA and Health Canada are both based on a year long exposure to radon. This extremely accurate test will take into account all of the daily fluctuations in radon and provide an average concentration.

Our Rapidos detector is for shorter measurements of at least 10 days. While not a traditional short-term test, our device combines the need for a quicker test with the proven accuracy of alpha track technology. Since it is not susceptible to the vulnerabilities that typically hinder a short-term test, you can easily see your radon level while leaving worry behind.

How many detectors do I need?

The number of detectors needed varies based on the type of structure being tested.

Residences

When testing a residence there are many factors to consider. How large is the home? How many floors does it have? Are there multiple areas that make ground contact? Which separate rooms are frequented heavily? It is recommended to place a test in the lowest lived in level of the home, any additional level of the home that touches ground, and any rooms that are frequently used and relatively closed off from a main portion of the level being tested. In most instances a test will be placed in the basement, any parts of the home on a slab or above a crawl space, and in any bedrooms, offices, etc. that are separate rooms in the basement or on the level being tested. It would take thousands of webpages to explain every homes scenario and/or best testing location so if you have any questions about a specific area of your home you can contact your local department of health to see if they have any protocols for testing in your area and then contact us to assist you in determining the right amount of kits for a residence.

Buildings and Schools

For buildings and schools people should check with their local department of health for any regulations and consult the AARST-NRPP protocol for “Schools and Large Building Measurements”.

Multifamily Buildings

In multifamily buildings, some states require certification for testing and protocol in the AARST-NRPP document “Multifamily Building Measurement”, should be followed.

I got my report, what does it mean?

On your report there is a lot of information. The detector number(s), location information, and your results. The main bit of information to look at is your Average Radon Concentration. This is the radon level recorded during the time the test kit was deployed. Next to that number there will be a +/- number called the standard deviation. This number is the variance in which your radon level may have fluctuated. It will always be a small number and have little to no impact on your average radon concentration and any decisions on fixing a radon level should be made solely on your average level.

The US and Canada have each set a guideline for exposure to radon and in the US it is 4.0 pCi/l and in Canada the level is 200 Bq/m3.

RadOnline

Where can I get a copy of my report?

If you need a new copy of your report, you can login at anytime to RadOnline and using your commission number and password retrieve a copy of your report. Alternatively, you may contact Customer Service with your commission number and password and they can send you a new copy.

If you have misplaced or lost your commission and password you can contact Customer Service with your name and address and they can try and find the report for you. Looking up reports this way will take a bit longer but they will respond to you and let you know it is in process.
