The photon fluence rate is 10^7 photons mm^-2 sec^-1 for a beam of gamma rays. One fourth of the photons have energies of 100keV, one half have energies of 80 keV and the remaining quarter have energies of 20keV. What is the energy flux density (energy fluence rate) of the beam? If the photon photon flux density (fluence rate) is constant, what is the energy fluence over an interval of 40 seconds?
