Question

A variety of radiation detectors are employed in radiation measurement for specific applications. For each of the following applications, describe which detector is best employed and give your reasons for this selection.

a. Exposure rate measurement in a gamma field from several different radionuclides.

Answer 1

For measuring exposure rate in a gamma field from various radionuclides, a scintillation counter is ideal due to its accurate detection and measurement capabilities of different gamma radiation energies.

Step-by-step explanation:

When measuring the exposure rate in a gamma field from several different radionuclides, the best detector to employ is a scintillation counter (scintillator). This choice is due to the scintillator's ability to detect and measure different energies of gamma radiation effectively.

The scintillation counter works by using a scintillator material that luminesces when excited by ionizing radiation, coupled with a sensor that converts the emitted light into an electric signal, thus allowing for precise measurements of radiation levels.
