Which unit can a radiation detection device convert ionizing radiation into?

• A. Milligray Per Hour (mGy/hr)
• B. Kilovoltage Peak (kVp)
• C. Line Pairs Per Millimeter (lp/mm)
• D. Milliampere-Seconds (mAs)

Answer: (A)

The device translates ionizing radiation into a dose-rate reading, expressed as milli-gray per hour (mGy/hr). This shows how much energy is being deposited per unit mass each hour, which is what a radiation detector is designed to measure and display. The other options aren’t readouts from detectors: kVp is the tube’s peak voltage, not a radiation measurement; lp/mm is a imaging-resolution unit; mAs is the product of current and time that governs photon production, not a detector reading. So the appropriate output unit for a detector’s measurement is a dose-rate like mGy/hr.
