Reviewers have asked us to consider whether there will be residual radiation problems if we employ SmCo5 for a pair of vertical bending magnets in the ANU upgrade of the MI8 Line. To explore the problem we will use a simple ratio to known materials in places where we have some experience. We will describe MARS calculations performed by Igor Rakhno using two nominal neutron spectra for iron, ferrite, and SmCo5. Results of a recent residual radiation survey of the relevant portions of the MI8 line are reported and simple calculations will be carried out to relate current experience to that expected for the new vertical bend location.
