Which of the following procedures is NOT typically included in field operations for using CRM devices?

Statistical analysis is generally considered a post-field operation task rather than a procedure performed during field operations with Continuous Radon Measurement (CRM) devices. Field operations focus primarily on the direct measurement and collection of radon data, which involves procedures like instrument checks to ensure the devices are working correctly, field duplication to confirm the accuracy of measurements through repeated tests in similar conditions, and comparison checks among different instruments or measurement sites to validate results.

In contrast, statistical analysis occurs after data collection and involves interpreting the gathered data to draw conclusions, identify trends, or assess compliance with radon level standards. Thus, while statistical analysis is critical to understanding and utilizing radon measurement data effectively, it does not fall under the scope of field operations conducted with CRM devices.
