placement for the uptake probe, turn the uptake probe so that the collimator opening is
facing upwards towards the ceiling. Gently place the active end of the rod source onto the
middle surface of the crystal. The rod should stand freely and not lean to the side.
• To ensure that the Cs137 source rod is consistently placed in the center of the
probe face, the Rod Source Holder may be purchased from Capintec
(reference CHAPTER 15: CLEANING AND MAINTENANCE, SECTION:

• you CAN fashion a piece of cardboard, Styrofoam or paper cup into a circle

This positioning will provide reliable measurements.
Note: Never put a sharp instrument like a pen into the Well or Probe.
