Nuclear Gauging System

▪ Some portion of the radiation can also be reflected and backscattered.

▪ The reflected and backscattered radiation also loses energy and intensity.

▪ The intensity of reflected and backscattered radiation can be calculated by:

I I = o 1 ( − e − ( /  )x )
en

I = intensity the scattered radiation

I = initial intensity before entering the material
o
2 -1
µ /р = mass absorption coefficient of the material (cm g )
en
-2
x = density thickness of the material (g cm )

▪ The radiation can also react with a material and produce secondary radiation.
