What is the main purpose of using duplicates in radon measurement?

The main purpose of using duplicates in radon measurement is to assess measurement precision. When conducting radon tests, having duplicate samples allows technicians to compare two measurements taken under similar conditions to gauge the variability or consistency of the results. This is crucial because it provides insight into how reliable and repeatable the measurement process is. If the results from the duplicate samples are close together, it indicates high precision in the measurements. This practice helps in ensuring that the radon levels reported are not only accurate but also consistent across repeated tests, thereby building confidence in the testing methodology and outcomes.

While it is true that using duplicates can contribute to enhancing overall accuracy and can indirectly indicate device calibration status, the primary function of duplicates is specifically aligned with precision assessment in measurement practices.
