Au-196 #5 irradiation
The link below will take you to an analysis of the photon spectrum observed when a mixture of Au + San in a crucible is irradiated for 1 hour using a 44 MeV, 2kW electron beam incident on a 4 mm W converter
The link below will take you to the 0.002" thick gold foil measurements
