Calibration

Definition

Calibration is the process of adjusting and verifying the accuracy of measurement instruments or systems by comparing their outputs against a known standard. This practice ensures that instruments provide reliable and consistent readings, which is crucial in fields like radiation detection and diagnostic nuclear medicine. Proper calibration allows for precise measurements, which are essential for accurate diagnostics, effective treatment planning, and safety in handling radioactive materials.
