In order to ensure an accurate test of the radon level in your home, you'll need to adhere to the conditions outlined below for a full 12 hours before the test begins, as well as during the test:Įntry doors should be kept closed, with the exception of normal entry and exitĪny fans that exhaust air outside or bring outside air into the house should be left off. This includes high-volume attic fans, whole house fans, and window fans. There are some exceptions, however: air conditioning systems that recycle indoor air, air-to air heat exchangers, and furnaces.Īny ceiling fan, dehumidifier or air cleaner within 20 feet of the monitor should not be used prior to or during the test period. Unless a fireplace is a primary heat source, it should not be used during the test period and the flu damper should be closed.Ĭlothes dryers, oven range hoods and bathroom exhaust fans can be used in moderation. If a radon mitigation system is already installed at the house, it should be running for at least 24 hours before the test and continuously during the testing period.

If a home is vacant, the heating or air conditioning system should be set between 67-77 degrees fahrenheit with the fan in AUTO mode.Because there are so many factors, it is not possible to predict the radon level in a home the only way to know your radon level is to test. Soil characteristics: Radon concentrations can vary enormously depending on the uranium content of the soil.The amount of radon in a home will depend on many factors including: The levels can vary dramatically even between similar homes located next to each other. The greater the source, the greater the potential that radon could enter a building.

Occupant lifestyle: The use of exhaust fans, windows and fireplaces, for example, influences the pressure difference between the house and the soil.Foundation condition: Foundations with numerous cracks and openings have more potential entry points for radon.Construction type: The type of home and its design affect the amount of contact with the soil and the number and size of entry points for radon.In addition, radon flows more easily through some soils than others for example through sand versus clay.

This pressure difference can draw radon indoors and influences the rate of exchange of outdoor and indoor air.

Weather: Variations in weather (e.g., temperature, wind, barometric pressure, precipitation, etc.) can affect the amount of radon that enters a home.

My radon level is quite high, what do I do next?

Home testing is only part of the solution, there is no reason to fear a high radon test result. No matter your level, there are radon mitigation methods that can successfully reduce your home to a safe level. If you’ve tested your home, and the radon concentration is above the Canadian guideline of 200 Bq/m3, Health Canada recommends that you take action to lower the concentrations. The higher the radon concentrations, the sooner action should be taken to reduce levels to as low as practically possible.
