Accidents, Loss, Damage, Fire, Theft
Remember the principles of health and safety in such situations:
time, distance and shielding. In case of one of the above situations:
• Limit access to the area.
• Report the incident to BERTHOLD TECHNOLOGIES; who will
advise what further immediate precautions to take and arrange
for quick support from a licensed person.
In case of loss or theft, notify the regulatory authority.
If the sealed radioactive substances are no longer contained, the
supervisory authority must be notified immediately; moreover,
steps have to be taken to ensure that the contamination cannot be
dispersed.
Proper handling and disposal of possibly leaking radioactive
sources or contaminated parts of the equipment must be coordi-
nated with the supervisory authority.
6.6.1 Malfunctions and Accidents
The Radiation Protection Regulation defines malfunction as an
event which for safety reasons prohibits continuation of the opera-
tion of the facility.
Malfunction
Malfunction means, that a device necessary to guarantee safe
operation of the facility, e.g. the seal of the active radiation beam of
the shielding, no longer functions properly.
Accident
An accident is an event which could expose persons to a radiation
dose which exceeds the permissible limits, or could cause contami-
nation by radioactive substances.
In terms of safety, malfunctions and accidents are very serious
events and appropriate steps must be taken immediately to pre-
vent hazards to persons as well as facilities, or to reduce them as
much as possible.
It is therefore important that the personnel is aware of preventive
measures and is prepared for possible accidents or malfunctions of
the facilities, so that dangerous consequences can be ruled out as
far as possible by a proper reaction of the personnel.
In any case, the Radiation Safety Manager who checks the situation
at site and takes all necessary steps to prevent unnecessary radia-
tion exposure of the personnel must be notified immediately.
The Radiation Safety Manager will then take appropriate measures
and will inform the official authority concerned, and, if necessary,
get further information from the manufacturer.
The necessary steps should be taken in the following order:

Locate source.

Check the function of the shielding.

Check effectiveness of shielding by measuring the dose rate.
