What do quality control spikes measure in radon testing?

Quality control spikes are used in radon testing to assess the accuracy of the measurement process. By introducing a known quantity of radon into the environment, testing professionals can evaluate how closely the results from the radon measurement devices align with the established known value. This process helps to ensure that the measurement instruments are functioning correctly and providing reliable results.

While precision refers to the reproducibility of measurements under the same conditions, quality control spikes specifically target the correctness of those measurements compared to a known standard, which is why they measure accuracy. Understanding the accuracy of measurements is crucial in radon testing, as it directly impacts the reliability of assessments for health risks associated with radon exposure.
