A robust conversion method of radioactivities between plastic and NaI scintillation well counters for long-term quality control and quality assurance.

Purpose: The purpose of this study is to specify a simple procedure for a robust data conversion of radioactivity value between plastic scintillator (PL) and NaI scintillator (NaI) devices.

Materials And Methods: The radioactivity estimate of 100 blood samples was measured by the two devices. The two radioactivities were plotted on the same graph.
