Nuclear Gauging System

Basic principles and techniques

▪ The transmitted radiation is reduced in intensity and energy.

▪ Its intensity can be calculated by:

I I = o e − ( / x ) 
en

I = intensity after passing through the material

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