Which of the following lists the two types of radon tests?

The correct choice identifies the recognized categories of radon testing, which are essentially categorized by the duration and method of testing. Short-term tests provide results over a brief period, usually ranging from a few days to a week, while long-term tests monitor radon levels for a minimum of 90 days, providing a more comprehensive assessment of radon exposure.

In the context of radon testing, passive and active tests are also legitimate classifications. However, passive tests require no external power source and rely on natural processes to collect radon samples, while active tests involve powered devices that continuously sample the air. Integrating and continuous tests, while they offer different methodologies, are not the standardized terms most commonly used for radon testing types.

Furthermore, room-specific and environment-specific tests do not efficiently categorize testing methods but rather indicate specific applications or conditions under which tests may be performed. Thus, the terminology of short-term and long-term tests stands as the most conventional and widely accepted differentiation in radon testing, highlighting their methodologies effectively.
