9 Radiation Protection Volume 1
9.3 Testing the Shutter Mechanism
The Radiation Protection Ordinance requires that regular functional
testing and maintenance are carried out on the shielding and the
inspection is documented. In establishing the testing interval for
periodic functional testing and maintenance of the source shielding,
the ambient and operating conditions of the measuring device, the
legal regulations and the permit conditions must be considered. The
functional checks and maintenance have to be carried out, however,
at least once a year.
The functional test is to ensure that the locking mechanism is work-
ing properly. It must be ensured that:
the closure moves easily and freely
the locking mechanism does not get jammed at any point in the
range of rotation
the beam path can be closed completely
If you notice a failure or you have doubts, please contact the
BERTHOLD TECHNOLOGIES service department.
