Point Level Orientation
The version of the source container with a beam exit angle of 0° is best suited for
point level detection. Make sure the radiation is directed exactly towards the
detector mounted on the opposite side.
To use larger exit angles (15°, 30°, 45° or 60°), you must certain the beam is
horizontal.
To make sure the beam is horizontal, you have to mount the source
holder so that the implied opening of the exit channel is in a horizontal position.
Mount the SHLD 2 as close as possible to the vessel. With large measuring
ranges and small vessel diameters, a gap may exist.
If there are gaps or empty spaces around the installation, provide protective
fences or grids to keep hands away from the dangerous
area.
You must mark
such areas accordingly.
