Safety Measures
When designing the installation of radiometric measuring systems,
the possibility that a fire breaks out must be considered. Flammable
substances must not be stored in the proximity of radioactive sub-
stances. They should be covered and protected properly to prevent
a possible spreading of the fire to the radioactive sources. It is man-
datory to coordinate all preventive measures against fire with the
local authorities, primarily with the fire department, which must be
informed about the type, scope and place of application of the radio-
active substances used, in order to be prepared in the event of fire.
When devising alarm plans, possible special features of the radio-
metric measuring system have to be mentioned; the Radiation
Safety Manager to be notified in the event of an emergency has to
be included in those plans as well, and also the address and phone
number of the regulatory authority.

Protection against Theft
Radioactive substances or facilities containing radioactive sub-
stances must be secured against unauthorized use. Fixed installa-
tions are, by their nature, protected against unauthorized use.
If facilities working with radiometric measuring systems are taken
out of service for a longer or indefinite period of time, the radioac-
tive sources together with their shieldings should be dismantled and
secured until the facility is taken into operation again.
Portable measuring systems, on the other hand, have to be pro-
tected by keeping them under constant supervision, or, if they are
not in operation, by keeping them in a locked room or container
which can be guarded against unauthorized access.
This is especially true for low activity test sources which are used,
for example, to check the function of dose rate measuring instru-
ments.
In the event that radioactive substances are lost, the Radiation
Safety Manager and the regulatory authority have to be notified
immediately.
In case of theft, the police must be informed as well.
