Sample Questions

Question 1
Which radiation detection instrument is MOST appropriate for measuring low-energy beta emitters such as H-3 and C-14 in liquid samples?
Ion chamber survey meter
Sodium iodide gamma spectrometer
Geiger-Mueller detector
Liquid scintillation counter
Question 2
What is the primary advantage of a high-purity germanium (HPGe) detector over a sodium iodide (NaI) detector for gamma spectroscopy?
Higher detection efficiency
Superior energy resolution
No cooling required
Lower cost and simpler operation
Question 3
A Geiger-Mueller detector reads 500 counts per minute at a known dose rate of 2 mR/hr. After exposure to a much higher radiation field, the instrument reads zero. What is the MOST likely cause?
The detector has experienced saturation or dead-time paralysis
The instrument is functioning correctly and the field is zero
The radioactive source has completely decayed
The battery has failed
Question 4
Which type of radiation detector operates on the principle of collecting charge carriers produced by ionization in a gas-filled volume?
Ionization chamber
Thermoluminescent dosimeter
Film badge
Scintillation detector
Question 5
What is the minimum detectable activity (MDA) of a counting system primarily dependent upon?
The energy of the emitted radiation only
The physical half-life of the radionuclide
The activity of the sample being measured
The background count rate and counting time
