Radon Test Kit

**Semantic type:** Manufactured Object

**Definition:** A device designed to determine the radon level in a building. Passive detectors are most common and detect radon using charcoal canisters, alpha track detection, or charcoal liquid scintillation. Tests are either short-term, monitoring for radon over a 2-90-day interval, or long-term, monitoring from 90 day to 1 year.
