Final Answer:
A dose calibrator is an example of 3) Scintillation detector.
Explanation:
A dose calibrator is a device commonly used in nuclear medicine to measure the radioactivity of a radiopharmaceutical. It falls under the category of scintillation detectors. In a scintillation detector, when ionizing radiation interacts with a scintillating material, it produces flashes of light (scintillations). These flashes of light are then detected by a photomultiplier tube, and the resulting electrical signals are converted into a measurement of radioactivity.Option 3 is the correct option.
The specific scintillating material used in a dose calibrator can vary, but it often involves crystals such as sodium iodide (NaI) or cesium iodide (CsI). The scintillation process allows for accurate measurement and calibration of the radioactivity in a sample. This is crucial in nuclear medicine applications, where precise dosages of radiopharmaceuticals are administered to patients for diagnostic or therapeutic purposes.
Understanding the type of detector used in a dose calibrator is important for professionals in nuclear medicine, ensuring accurate and safe administration of radiopharmaceuticals. The principles of scintillation detection provide a reliable method for measuring radioactivity and play a vital role in the practice of nuclear medicine.
