Source Rod Positions
As shown below, the source rod can be placed in the SAFE
position, background (BGD) position, backscatter position, or the
direct transmission position. When not taking measurements,
keep the source rod in the SAFE position at all times.
Figure 4. Source Rod Positions
In the backscatter position (position below background), the tip
of the rod sits flush with the bottom of the gauge, so no drilled
hole is necessary.
In the direct transmission positions, the source rod extends into
a pre-drilled hole described in the next chapter.
