What is the primary function of a dose calibrator in nuclear medicine?

The primary function of a dose calibrator in nuclear medicine is to assay the amount of radioactivity in a sample. This instrument is essential for ensuring accurate measurement of radioactivity before radiopharmaceuticals are administered to patients. It provides reliable quantification of radioactivity, which is crucial for determining the appropriate dosages required for diagnostic or therapeutic procedures. The calibrator works by measuring the emissions from the radioactive material within a specific geometry, allowing for precise and consistent activity measurements.

Accurate dosimetry is vital not only for patient safety but also for the effectiveness of the nuclear medicine procedures being performed. By ensuring that the correct amount of radioactive material is used, healthcare professionals can optimize the diagnostic or therapeutic outcomes while minimizing potential risks associated with radiation exposure.
