The measurement of the output spectrum of a cobalt 60 teletherapy unit
The output spectrum of radiation emerging from a Coteletherapy unit contains a certain amount of low energy radiation in addition to the primary Co60 -rays with energies of 1.17 and 1.33 Mev. Since the beam strength is approximately 2 x 109 photons/cm2/sec at 80 cm from the source, direct measuremen...
