1. G2p Safety Readiness Review January 17, 2012 Expected Radiation Exposure Levels from Activated Local Dump George Kharashvili, Radiation Control

2. 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:

3. 15 minutes after the end of the run:

4. 30 minutes after the end of the run:

5. 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.

6. 15 minutes after the end of the run - dump cartridge has been replaced:

7. 30 minutes after the end of the run - dump cartridge has been replaced:

8. 1 hour after the end of the run - dump cartridge has been replaced:

9. Expected radiation exposure levels at the floor 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:

12. Floor level 30 minutes after the end of the run - dump cartridge has been replaced:

13. Expected radiation exposure levels 1m above the top platform 15 minutes after 5- day long irradiation of the local dump for 20 hours per day with 100-nA, 3.35-GeV e - beam:

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

16. 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.
