  • RO-2
  • None of the above

Which type of detector is ideal for dose rate measurements?

  • Ionization Chamber (correct)
  • Recombination
  • RO-2
  • None of the above

What are the advantages of detectors operating in the ionization chamber region?

  • Accuracy, response proportional to dose rate, high levels of radiation measurement
  • High levels of radiation measurement, stay time and dose assessment
  • Stay time and dose assessment, less regulated power supply needed
  • Accuracy, response proportional to dose rate, less regulated power supply needed (correct)

Flashcards

Recombination Detectors?

Detectors relying on recombination are not used in radiation detection.

Best Detector for Dose Rate?

Ionization chambers are ideal because their output is directly proportional to the intensity of radiation.

Advantages of Ionization Chambers?

High accuracy, a response proportional to the dose rate, and less stringent power supply requirements.
