Although the higher concentrations of radon are typically found at ground level or below, it is not impossible for second and third story levels or higher to also have a radon concentration above 4.0 pCi/L. Radon can move through air shafts or elevators in taller buildings. It is just a good rule of thumb to simply conduct a test to ensure that you are not unknowingly exposing yourself or your family to high levels of radon gas.
HUD lending requirements for multi-family living have recently changed. HUD now requires that if any multi-family structure, intended to be rented, is being built or refinanced with a HUD loan, the loan applicant must randomly test 25% of the ground level units. If any of the units come back with a radon concentration of 4.0 pCi/L or higher, the entire building must be mitigated, not just the unit that tested high.
If you are unsure if the apartment or condo you are renting has been tested for radon, you should ask the owner of the property. If a test has been conducted, you can ask for a copy of the test results. Another option is to have a radon test conducted for peace of mind.
If your radon test comes back with radon levels of 4.0 pCi/L or above, notify the landlord in writing and discuss the need for additional testing or mitigation.
