Answer :
Final answer:
Dose calibrators use an Ionization chamber to measure radiation dose, which quantifies collective ionization from ionizing radiation.
Explanation:
The type of radiation detector used in dose calibrators is the Ionization chamber. This device is designed to measure the dose of ionizing radiation directly, which makes it well-suited for calibrating doses in nuclear medicine and other radiological applications. Unlike the Geiger-Müller counter, which detects individual radiation events, and the Scintillation detector, which measures radiation through light flashes produced by a scintillator, the ionization chamber measures the collective ionization of a gas caused by incident radiation. This allows for the precise quantification of radiation dose.
