Expected radiation exposure levels at beamline level 5 minutes after 5-day long irradiation of the local dump for 20 hours per day with 100-nA, 3.35-GeV e- beam:

Expected radiation exposure levels in the area adjacent to the local dump –This area will have to be accessed in order to replace the cartridge.

Top platform 30 minutes after the end of the run - dump cartridge has been replaced:

Conclusions:
• In general, radiation safety issues are expected to be comparable to a typical high current experiment;
• High Radiation Areas expected around the dump – physical access controls may be required;
• Radiation areas are expected in several meter radius around the local dump at the floor level and the top platform level;
• Routine access to target chamber at both platform levels will likely require a standing RWP.
