Which of the following describes the three types of radon tests?

The three types of radon tests are indeed best described as Grab Samples, Integrating Tests, and Continuous Tests.

Grab Samples refer to individual measurements taken at a specific point in time, providing a snapshot of the radon level in the environment at that moment. These tests are typically used in situations where immediate results are needed, although they do not provide information about radon fluctuations over time.

Integrating Tests, on the other hand, involve devices that collect radon data over a set period, allowing for an average radon level to be determined. These tests can span several days or weeks and give a better representation of radon exposure than a single measurement.

Continuous Tests utilize electronic monitoring equipment to constantly measure radon levels, providing real-time data and allowing for immediate response if levels exceed safety thresholds. This type of testing can reveal variations in radon levels throughout the day or week, capturing fluctuations that may occur due to changes in weather or building occupancy.

The other options, while related to radon measurement concepts, do not accurately categorize the typical approaches to radon testing in the same structured manner as Grab Samples, Integrating Tests, and Continuous Tests.
