Radiation damage to electronics in accelerator tunnels may require using long cable runs to locations where radiation is sufficiently reduced. hen constraints such as cable capacitance, high voltages, and/or frequency response suggest having electronics in the tunnel, a study of the radiation loss environment may help identify suitable locations. Using Al Tag activation techniques, we measure the fluence of hadrons in regions of interest in the MI600 - MI100 tunnel locations. We lso have placed Al Tags adjacent to three gas ionization beam loss monitors which allows us a new calibration of their response.
