Bruce and others:
This right on.
"Radiological Safety Aspects of the Operation of Electron Linear
Accelerators", Technical Report Series No.188, IAEA, Vienna 1979 by
William P. Swanson.
Also helpful may be, "Accelerator Health Physics", Academic Press, 1973,
by Patterson and Thomas. This is out of print but your university
library should have a copy.
