I perform an activation study to estimate the residual dose rate from the activation drum. I use 241Am-Be with the energy sampled of the respective spectrum (I set the distribution to be isotropic in the BEAM card). Again, I have neutron emission rate (n/s) obtained using the relation from literatur…

As neutron irradiation profile, you do not need to input specific intensities for different neutron energies (which is not possible in the IRRPROFIle card), rather the neutron emission rate (neutrons per second) integrated over the energy spectrum, as @agerbers indicated above. In parallel, you need…

Dear @Motlatsi_Vincent,

in addition to Alex’ answer, I would like to point you to this topic:
