CHAPTER 2
THEORY OF OPERATION
This chapter provides a brief description of the theory of operation
of the Troxler Model 3430 Plus and 3440 Plus Surface Moisture-
Density Gauges. The
direct transmission
and
backscatter
modes of
operation are illustrated, along with an explanation of the
cesium-137 source, americium-241:beryllium source, and detector
geometry.
