6.2 Visual inspection
The visual inspection must be carried out by persons who are at least employees
with general knowledge at the following intervals:
•
before initial commissioning
•
with every repair that may be required
•
regularly at least every six months
•
before dispatch
When determining the intervals for the visual inspection, the following
conditions are to be considered:
•
ambient conditions (outdoors, rain, sunlight, wind)

•
operating conditions (degree of utilisation of the plant, misuse)
Performing the visual inspection:
1. Check the shield for obvious damage (dents, cracks, holes etc.) and corrosion.
2. Only before dispatch: Check if the shield is in closed position and if the
padlock as well as the transport securing device are installed.
Tip
If there is any doubt regarding the actual position of the locking mechanism:
Check the dose rate at the shield using a dose rate measuring device. If the
shield is closed, the dose rate in the direction of the beam may not be
significantly higher than at other parts of the shield.
3. If any defects are identified during visual inspection, inform the radiation
safety officer who will initiate the measures required for repairing the
defects.
For further information, please contact the manufacturer.
6.3 Leak test
Depending on the supervisory authority responsible for the area where the
source is used, regular leak tests must be carried out. These tests are to be carried
out at the discretion of the competent supervisory authority either by an
authorized expert or by the manufacturer. For this test, the corresponding source
documentation must be made available.
