What does the minimum detectable concentration refer to?

The minimum detectable concentration (MDC) is a critical concept in radon measurement, referring specifically to the lowest concentration of radon that can be reliably detected by a particular measurement instrument or method with a specified level of confidence. In this case, a 95% confidence level indicates that there is a high degree of certainty that the measurement is valid and accurately represents the concentration present in the environment.

This parameter is essential for ensuring the reliability of radon testing and making informed decisions about mitigation and health risks. Knowing the MDC helps professionals understand the limitations of their measurement methods and ensures that they are detecting radon levels that could be significant for health assessments and remediation actions. Understanding the MDC also emphasizes the importance of utilizing appropriate technologies and methodologies in radon testing to achieve credible results.
