What is the primary challenge of placing detectors in kitchens and bathrooms?

The primary challenge of placing detectors in kitchens and bathrooms is high humidity levels. High humidity can significantly affect radon measurement devices. It can lead to false readings or fluctuations in the radon concentration indicated by the detectors. When humidity is high, the moisture can interfere with the sensor's ability to accurately detect and quantify radon levels in the air.

In addition to influencing readings, high humidity can also cause condensation, which might damage certain types of detectors designed for radon measurement. This makes it crucial for radon testers to avoid placing detectors in these areas or to use specialized equipment that can handle high moisture levels. Thus, ensuring accurate radon levels require careful consideration of environmental factors like humidity, particularly in spaces such as kitchens and bathrooms where moisture is prevalent.
