Caesium

Cobalt (60Co) and caesium (137 Cs) are the most widely used sources of gamma radiation. 60 Co produces gamma rays with energies of 1.173 and 1.332 MeV and has a half-life of 5.27 years, whereas 137 Cs produces gamma rays with an energy of 0.662 MeV and has a longer half-life of 30.1 years.

Caesium

Caesium gets its name from the Greek for heavenly blue. Not for its eyes (it's only an element!) but less romantically for the appearance of its emission spectrum in the spectroscope. Caesium was discovered in 1860 by Robert Bunsen (he of the burner fame) and physicist Gustav Kirchhoff.
