7 Maintenance and fault rectification
7.1
Cleaning
Clean the instrument in regular intervals. Note the following points:
•
Clean the instrument of substances that can impair the safety
function
•
Remove deposits of medium or other substances that could impair
or prevent the source holder from switching over
•
Take care that the lettering remains legible
•
Clean the adhesive labels and the connection box (version with
pneumatic switching ON/OFF) only with water (e.g. with slightly
damp rag)
•
Avoid creating electrostatic charges on the instrument. Never rub
with dry cloth when cleaning
Warning:
Take note of all safety instructions in this operating instructions
manual when cleaning.
7.2
Maintenance
If the device is used properly, no special maintenance is required in
normal operation.
Along with the regular inspections of the system, we recommend the
following checks:
•
Visual check for corrosion on the housing, the weld joints, the
outer parts of the source insert, the lock, the lock washers
•
Test of the mobility of the source insert (switching ON and OFF
function)
•
Assessment of the legibility of all labels and warning signs
•
Stability and firm attachment of the source holder
Caution:
If you are not sure of the proper functioning or condition of the instru-
ment, contact immediately the responsible radiation safety officer for
further instructions.
Caution:
Repairs or maintenance work beyond the scope of the usual inspec-
tion may only be carried out by the manufacturer, the supplier or
specially authorized persons.
If there are clear traces of corrosion on the source container, the local
dose rate (µSv/h resp. mR/h) must be measured in the surroundings.
If the rate is clearly above the values during normal operation, then
the area must be cordoned off and the responsible radiation safety
officer informed.
Corroded instruments and lock washers must be exchanged as soon
as possible.
