What method can help reduce radon entry into a home?

• A. Opening all windows
• B. Closing and caulking all cracks
• C. Using an air purifier
• D. Installing a ventilation fan

Answer: (B)

Sealing and caulking all cracks in a home is an effective method for reducing radon entry. Radon is a naturally occurring radioactive gas that can seep into buildings through cracks and openings in the foundation, walls, and floors. By closing these gaps, you can significantly decrease the pathways available for radon to enter the home. This approach is particularly beneficial as it targets the specific points of entry and creates a barrier that limits the amount of radon that can accumulate indoors. In contrast, opening windows may temporarily reduce radon levels by increasing ventilation, but it is not a viable long-term solution for preventing radon entry. Air purifiers may help in reducing indoor air pollutants but do not specifically target radon, which requires focused mitigation strategies. Installing a ventilation fan can improve air circulation but may not address the root cause of radon entry unless combined with sealing efforts. Thus, sealing and caulking cracks provides a direct and effective means of controlling radon levels in the home.
