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.

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).
