Exam Questions and Answers
100% Pass
Radiation detectors - CORRECT ANSWER:-Converts radiant energy into an
electronic signal 'transducer'.
Gas filled detectors, Scintillation detectors - CORRECT ANSWER:-2 types of
radiation detectors.
Gas filled detectors - CORRECT ANSWER:-- Radioactivity interacts with gas
molecules inside the detector which results to ionization, creating voltage potential,
translated into the measure of radioactivity.
- Filled with air on inert gasses such as argon or xenon
Basic Ionization chamber, Geiger muller counter - CORRECT ANSWER:-2 Types
of gas filled detectors:
Gas filled detectors - CORRECT ANSWER:-depends on ionization
Scintillation detectors - CORRECT ANSWER:-depends on excitation
Basic ionization chamber - CORRECT ANSWER:-cutie pie, Dose calibrators
, Geiger muller counter - CORRECT ANSWER:-contamination and survey meter
Survey instrument - CORRECT ANSWER:-- Instrument that locate
contamination or detect radioactive material. Radioactive material detected in the
attached probe causes electronic pulses that move the meter needle and make an
audio response.
- The meters read out in counts per minute 'cpm' and can be calibrated to report
mR/hr. There is a large selection of survey instrument available, designed for the
detection of a specific type of radiation. One of the most common survey meters,
can be used with various probes, depending on your needs and radionuclide.
- Make sure you have the right probe, such as pancake or scintillation probe.
Geiger muller counter - CORRECT ANSWER:-- is a device used for the detection
and measurement of all types of radiation: alpha, beta and gamma radiation.
Basically it consists of a pair of electrodes surrounded by a gas. The electrodes
have a high voltage across them. The gas used is usually Helium or Argon.
- When radiation enters the tube it can ionize the gas. The ions (and electrons) are
attracted to the electrodes and an electric current is produced. A scaler counts the
current pulses, and one obtains a "count" whenever radiation ionizes the gas
Radiation survey meter - CORRECT ANSWER:-is a portable radiation detection
and measuring device to measure the "Ionizing Radiation Field" in Dose or Dose
rate
