Which location is considered unsuitable for radon testing?

Kitchens are considered unsuitable for radon testing primarily due to their specific characteristics and conditions that can affect radon measurements. In residential settings, kitchens often have various appliances such as stoves, refrigerators, and dishwashers, which can introduce drafts and air movement. This can lead to fluctuations in indoor air pressure and airflow patterns, potentially skewing the results of radon testing.

Furthermore, kitchens commonly have higher humidity levels and might frequently have open windows or doors for ventilation during cooking, making them less stable environments for obtaining accurate radon measurements. It is essential to conduct radon tests in conditions that mimic typical living conditions, which are generally more stable in less frequently used areas like bedrooms or basements.

In contrast, areas such as dining rooms, bedrooms, and sunrooms can provide a more accurate representation of occupant exposure to radon because they are typically used more consistently and have fewer factors that can disrupt air flow or humidity levels.
