2018/2019 FIRST SEMESTER EXAMINATION
Course title: Nuclear Instrumentation and Dosimetry

Instructions: Answer four (4) questions (two in each section).

Section A

Section B (answer two questions in this section)

a) Radiation energy spectra can be categorized into two main groups: those that consist of discrete energies (line spectra) and those that consist of a broad distribution of energies (continuous spectra). For each of the radiation sources listed below, indicate whether "line" or "continuous" is a better description:

- Alpha particles
- Beta particles
- Gamma rays
- Characteristic X-rays
- Conversion electrons
- Auger electrons
- Fission fragments
- Bremsstrahlung
- Annihilation radiation

Final answer:

Explanation of line spectra and continuous spectra in radiation sources


Explanation:

Line spectra consist of discrete energies, while continuous spectra consist of a broad distribution of energies.

Examples of radiation sources categorized into line and continuous spectra are:

  • Alpha particles - Line spectra
  • Beta particles - Continuous spectra
  • Gamma rays - Continuous spectra
  • Characteristic X-rays - Line spectra

Understanding these distinctions is crucial in nuclear instrumentation and dosimetry.
