What are the two concentric sleeves in a dose calibrator known as?

• A. Anode and Cathode
• B. Source and Detector
• C. Outer and Inner sleeves
• D. Input and Output

Answer: (A)

In a dose calibrator, the two concentric sleeves are referred to as the source and detector. The source sleeve is where the radioisotope being measured is placed, and the detector sleeve houses the detection apparatus that measures the radiation emitted by the source. This setup is essential for accurate activity measurements of radiopharmaceuticals. The source sleeve allows the calibrated source to be positioned correctly to ensure maximum interaction with the detector, which is sensitive to the type and energy of radiation emitted from the source. The design facilitates the measurement of the radioactivity, making it crucial in nuclear medicine for ensuring patient safety and accurate dosing. Understanding this configuration enhances the knowledge of how a dose calibrator operates and its role in PET imaging and radiopharmaceutical therapy.
