3.2. The rating determines the sensitivity material thickness
To compare, evaluate the sensitivity of the method of determining the thickness of the material between Peak to Valley methods and conventional methods, we have conducted a simulation with the physical changes material thickness of two copper (8.96g / cm3) and aluminum (2.699g / cm3) with a thickness ranging from 0 to 3.5cm. Source situate the detector surface is 15cm. Beer is placed between the source - the detector and the detector surface is 10 cm. Tables 2 and 3 shows the peak to valley value and performance of 137Cs sources.
