Preparation for Sample Measurement
The transition from radiochemical separation described in Chapter 6 to instrumental radiation detection in Chapter 8 is source preparation for counting. The analyst wants to prepare a source that represents the radionuclide in the collected sample, can be measured reliably by its radiation, and is stable. The analyst selects a detector that is sensitive to the radiation that characterizes the radionuclide, stable as defined by its QA program, and calibrated for efficiency and—if needed—energy. Source preparation concerns are addressed here for the four types of detectors that are described in Chapters 2 and 8, but these considerations can apply to sources prepared for measurement by other detectors.
