Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that radon mitigation systems effectively reduce indoor radon levels in homes?

Yes. The CDC and a Wikipedia reference state that proven radon reduction systems, such as soil depressurization with vent pipes and fans, effectively lower indoor radon levels in homes. Additional studies address mitigation in schools, basements, or ventilation experiments, supporting the general principle in narrower settings.
