Emergency procedure
9.1
Objective and overview
This emergency procedure shall be put into effect immediately to secure an area in the
interests of protecting personnel where an exposed source is known, or suspected, to exist.
Such an emergency exists when a radioisotope is exposed either by it becoming separated
from the source container or a source container cannot be put into the "AUS/OFF" position.
This procedure will safeguard the personnel until the responsible radiation safety officer
will attend site and advise on corrective action.
The custodian of the radioactive source (the customer's designated "authorized person") is
responsible for observing this procedure.

In this case the radiation source container should be unbolted from its mounting position
and

towards a very thick wall, or
• in case the radiation emission channel is located vertically: put the source container on
its device base on the ground
