In this first section, an introduction to the main gamma sourcesis given,
together with their associated values, peak energies and half-lives.
After completing this section, you should be able to:
- Identify the main gamma sources from the energy position at which
the peaks appear in the spectrum;
- Identify and distinguish between gamma sources;
- List activity and main energies of a gamma source.
From these, a spectrum of a gamma ray should be energy calibrated by
the characteristic of that known gamma source.
