Yes in that webpage is quoted: "where it appears that the average secondary electron liberated by 6 MV photon has 1-to 2 MeV" and I have looked at Johns & Cunningham where similar calculations have been done, but cannot find anywhere where the above data came from. May thanks anyway A Visioli

My recollection is that the 1.2MeV average/mean comes from the spectrum of probabilistic energies of accelerated electrons. Now that you ask, it is definitely true for photons, but I can't ever recall a curve for electrons. specifically. Others might have a more specific answer.

I am trying to work out what happens in tumour when hit by 4 - 6 MV beam in the presence of gold nanoparticles. Hence my interest in section 8.3.2 (webpage above) where it appears that the average secondary electron liberated by 6 MV photon has 1- 2 MeV. Could anyone please give me the references where all this data (energy of secondary electrons page 8.3.2 ONLY) comes from, as I need to quote it for possible PhD presentation. Many thanks for your hep and any input.
