Emergency procedure
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 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.
Emergency procedure 1. Determine the unsafe area by on-site measurement.
2. Cordon off the concerned area by yellow tape or rope and post international radiation warning
signs.
The shutter cannot be switched to the "OFF" position.
In this case the radiation source container must be unbolted from its mounting position.
CAUTION
!
Dismounting
‣ Point the emission channel towards a very thick wall (e.g. steel or lead) or mount a thick plate (e.g.
steel, lead) in front of the emission channel.
‣ Personnel should at all times be behind the source housing, not in front of the emission channel.
The radiation source is outside from the source container.
In this case, the radiation source must be placed at a safe location or additional shielding must be
applied.
CAUTION
!
Handling of the source
‣ The source should only be handled via pliers or tongs and held as far away from the body as
possible.
‣ The time needed for the transport should be estimated and minimized by rehearsal without
radiation source prior to execution.
Notification to authority 1. Make necessary notifications to local authorities within 24 h.
2. After thorough assessment of the situation, the responsible radiation safety officer, in conjunction
with local authorities, shall agree a remedy to the specific problem.
NOTICE
National regulations may require other procedures and reporting obligations.
