Preparing for Transportation
When the line source housing is going to be transported, e.g. being shipped from the supplier to
the customer site, the shutter is locked in the closed position. This prevents uncontrolled radiation
from the source if the shutter lever on the line source housing should be activated by mistake.
The shutter is locked by inserting two 3 mm transportation screws into the line source housing and
through dedicated holes in the shutter plate as illustrated in Figure 12.21.
