What radon is, in one paragraph
Radon is a naturally occurring radioactive gas produced by the decay of uranium in soil and rock — and Colorado's geology produces a lot of it. It's colorless, odorless, and tasteless, so the only way to know your level is to test. Long-term exposure to elevated radon is the second leading cause of lung cancer in the United States, according to the EPA. The risk is real but entirely manageable: test, and if levels are elevated, mitigate.

No — not on its own. Colorado's health department states that caulking and sealing cannot stop radon by itself; sealant dries out over time and it's impossible to seal every entry point. Sealing is done as part of a mitigation system, never instead of one.
Most residential systems are installed in a single day — typically 4–8 hours. A follow-up test a few days later confirms the system brought your level down.
