These supplementary instructions describe the loading and exchanging of the emitter for source containers VEGASOURCE 31 and 35.
Carefully read this supplementary instructions and the corresponding
operating instructions of the source container and carry out the work
only after you have completely understood all instructions.
It is absolutely necessary that you take note of all safety instruments,
particularly of the instructions concerning radiation safety.
Check if the source capsule fits the existing source holder of the
source container. Compare the data in the shipping papers of the
source capsule with the data of the source container.

Labelling
l All maintenance work such as dismounting or exchanging the
radioactive source must only be carried out by authorized,
qualified personnel monitored for radiation exposure according to
the local legislation or the handling permit. Take note of the
specifications of the present handling permit. All conditions on site
must be taken into account.
l All work must only be carried out from a protected location
(shielding). Avoid risk to other persons through suitable measures
(e.g. safety fence, etc.).
l Make all necessary preparations for exchanging the source to
ensure that the work is carried out as fast as possible. Get all
required tools and accessories ready before you start work.
l Before starting the work, get a suitable, shielded vessel ready for
holding the exchanged emitter.
l Observe all the instructions of this supplementary instructons
manual for emitter exchange.
l Never touch the source capsule directly, but use a suitable
gripping device or a manipulator. Keep a distance of at least 10 cm
(4 in).
l Check all O-rings and seals when exchanging the emitter and
replace them, if necessary.
l Check the function of the switching facility of the source container
before installing or exchanging a source capsule (ON/OFFswitching).
l When system inspections are carried out, always set the source
container to position OFF and secure this position with a lock
against inadvertent switching on.
l If possible, practice this procedure, especially the handling with
the gripping device or suitable manipulator, in advance.
l Pre-printed type label, stainless steel 107 x 17 mm (4.21 x 0.67 in)
l Pre-printed type label, stainless steel 55 x 45 mm (2.17 x 1.77 in)
l Pre-printed adhesive type label, 48 x 30 mm (1.89 x 1.18 in)
l 4 grooved pins
l Sealing wire and seal
l Adhesive label "Radioactive"
When loading a source container or exchanging a source, the
corresponding type labels of the source must be permanently lettered,
e.g. with punch-type letters.
With sources exceeding a certain level of activity, the warning "Highly
radioactive source" must be stated on the type label.
This is the case for Co-60 with an activity ≥ 4 GBq (108 mCi) or for
Cs-137 with an activity ≥ 20 GBq (540 mCi).
