The distance from the source shieldings to the vessel surface is
designed such that reaching into the beam path with the hand is
prevented (reference value approx. 20mm).
Figure 2-24 Distance of the source shielding from the vessel surface
The dimensional drawings show the size of the different shieldings,
see section 6.5on page 2–273.
Figure 2-25 shows a proposal for a mounting bracket for the source
shielding. The size and rigidity of the mounting bracket has to
match the size and weight of the shielding. The bracket has to be
mounted in the appropriate height, if possible, directly on the ves-
sel or via an external supporting structure.
