The U.S. Environmental Protection Agency recommends that indoor radon levels be below what threshold?

2 picocuries per liter of air
4 picocuries per liter of air
10 picocuries per liter of air
8 picocuries per liter of air

The correct answer is: 4 picocuries per liter of air

The U.S. Environmental Protection Agency (EPA) recommends that indoor radon levels be below 4 picocuries per liter of air. This threshold is set based on health assessments that indicate prolonged exposure to radon at levels above this guideline significantly increases the risk of lung cancer. The EPA's stance is that while no level of radon is completely safe, keeping levels at or below 4 picocuries minimizes potential health risks. On the other hand, levels above this recommended threshold, especially at higher concentrations, warrant immediate action such as testing and mitigation efforts to ensure indoor environments remain safer for occupants. This guideline is based on extensive research into the impact of radon exposure on health, making it key knowledge in the context of real estate and leasing practices involving residential properties.
