Figure 7

Scattering angular distribution. The figure shows the angular distribution P(θ) of single scatterings of a primary ray that drops its energy in the window (115, 140 keV) and (50, 150 keV) for99mTc and90Y, respectively. The incident beam hardening is neglected (scatter and primary emission point close together).
