Ace the 2026 Health Physics Challenge (PMT 102A) – Radiate Success with Every Question!

To measure gamma dose rate, you need a detector that is sensitive to gamma photons and a readout calibrated to report dose rate (in units like Sv/h or Gy/h). The UDR-13 is designed as a gamma dose-rate meter, meaning it uses a gamma-sensitive detector and calibrated electronics to provide a direct readout of how fast gamma radiation is delivering dose to the area being measured. The other devices are not configured for gamma dose-rate measurement in the same way—they are used for different measurement purposes or for detecting other types of radiation. So the UDR-13 is the appropriate instrument for gamma dose-rate readings.
