10.3.1 Source Replacement Procedure
Fig. 10-4 Dismounting rod source shielding
Unscrew the head flange (1) using a suitable Allen key.
Open the locking cover (2).
Health hazards due to radiation!
Do not remove the source from the shielding!
Do not touch the source to prevent a high partial body dose. Touch
the source only with a tool that allows you to hold the source easily
and safely, for example, with a pipe wrench. Do not press the pipe
wrench too hard to avoid damage to the source. Keep the source
far away from your body and set it down behind an auxiliary shield-
ing.
Remove source from shielding Pull out the rod source (4) using the brass extension bar (3),
hold it with two pairs of pliers and insert it into a transport-
shielding. Unscrew the extension bar(3) first using two pairs of
pliers.
If necessary, clean and grease the thread on the source holder
and the shielding.
Pull the new source out of the transport shielding so much that
the brass extension bar can be fixed at the top with screws.
Make sure not to mix up the parts, especially when working
with multi-part sources.
Make sure the source is not mixed up with the new or another
source.
