Adhesive label "Radioactive"
When loading a source container or exchanging a source, the corre-
sponding 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).
