Hazards due to nuclear radiation!
Do not remove the source from the shielding!
Do not touch the source to prevent a high partial body dose. Only
touch the source with tools that allow you to grab the source easily
and safely, e.g. a pipe wrench. Do not push the pipe wrench tight
too much in prevent damage to the source. Hold the source far
away from your body and put it down, if possible, behind an auxil-
iary shielding.
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 that no mix-up with the new or other sources can occur.
Install new source Pull the new source out of the transport shielding using the pair
of pliers and place it into the working shielding.
Attach the brass cover (2) again after you have checked if the
O-ring seal is clean and undamaged.
Attach head flange again and carefully secure it with screws.
Check the proper ON/OFF function.
Carefully close the transport shielding again, after you have put
the old source into the transport shielding.
Set up the working shieldings as planned. With multi-part
shieldings be sure to observe the correct order.
Replace type label Replace the type label on the shielding or attach the new source
number.
The special regulations regarding labeling and transport of the
shielding back to the manufacturer have to be observed. If in
doubt, please contact BERTHOLD TECHNOLOGIES' Source Trans-
port Manager.
This completes the source replacement.
