J. R. Macdonald Laboratory Tandem/LINAC Accelerator
Attended Operations Policy
(Revised: 30 November 2000)
To ensure the safety of laboratory personnel and provide protection
for laboratory equipment, the following guidelines are provided:
-
If an operation produces an area with a radiation level greater than
2 mrem/hr (other than the area inside the Tandem tank chains and inside
the LINAC shielding wall), at least one person familiar with the
operation must be in the lab during the operation.
-
If the Tandem accelerator terminal voltage is greater than 5 MV, at
least one person familiar with Tandem operations must be in the
laboratory during accelerator operations.
-
If none of the items above apply, then the operation may be left
unattended provided that a method for contacting the person responsible
for the operation is posted on the status board.
