Frequently Asked Questions
Q: What is radon, and why should I care?
A: Radon, is the second leading cause of lung cancer, and the first leading cause among non-smokers. It is a radioactive, colorless, odorless, tasteless noble gas, occurring naturally as a decay product of radium. Radon comes from the ground, and is everywhere in our atmosphere. However, its concentration can vary widely in buildings where it can build up in the interior air. For more info on radon gas, read the Wikipedia page here.
Q: Our radon test came back at over 4.0 pC/l. Should we be concerned?
A: Any radon level above the EPA recommended action level of 4.0 pC/l can be mitigated with a radon reduction system. These systems are not complicated or expensive. So, there should be no need for major concern if this involves a property being prepared for sale. But, after a mitigation system is installed, the radon levels should be tested again to make sure that the system is effectively keeping the radon level below the EPA recommended action level.
Q: Our radon test shows a concentration below 4.0 pCi/l. What does that mean?
A: A radon average that is less than the EPA recommended action level of 4.0 pCi/l does not require a mitigation system. A homeowner can always decide and choose to have a mitigation system installed, even with a radon test average below 4.0 pCi/l. That is just a choice for the homeowner to make.

Q: There is a unit on my property that says "Radalink" on it. What's going on?
A: It is possible that your property is being tested for radon gas by your property inspector. Please do not touch or move the unit, or change the closed house conditions of your property. That is, do not change the status of heating or air conditioning, and do not open doors or windows, except to enter or exit quickly from the first floor doors. Contact your property inspector if you have additional questions about the status of your radon test.
Q: Does the monitor emit radiation or anything harmful?
A: Our monitors only take readings and do not emit any radiation or chemicals, and are in no way harmful to people or pets.
Q: What exactly does the Radalink radon monitor record?
A: Our monitors record radon concentration, temperature, barometric pressure, and relative humidity once per hour for the duration of the test. Our monitors also have a sensor that detects if the monitor has been moved during a test.
Q: Can we open our windows during the test?
A: All doors and all windows on all levels of the house must be kept closed, except for normal entry and exit through first floor doors. Heating and air conditioning equipment should operate normally. Window or wall mounted air conditioners may be used if the fresh air damper is set to the closed position. Fireplaces and wood stoves may not be used unless they are the primary heat source for the house. Whole house fans may not be used during the test.
Q: How long does the radon test last?
A: Tests take a minimum of 48 hours to complete. Radalink radon monitors can collect data for up to 5 days.
Q: How much does it cost to have my property tested for radon?
A: Radon test costs can vary, depending on the size of the property, the state requirements of the testing process, and the pricing offered by the inspector that you hire to conduct the test. Typically prices range from $75 to $250 per test.
Q: Where can I find an inspector to conduct a test at my property?
A: You can search for Radalink licensed radon inspectors by zip code, and other advanced methods, using our online search tool found here.
