✓ Isotope classification screen.
The Isotope Classification screen is shown in figure 4.13 below. To access the screen, touch tab menu along
the bottom of the Identification screen as shown in figure 4.12, and swipe left or right or press left/right
function button on the handle.
In this mode, the real-time Dose Rate measurement of identified nuclides is graphically displayed in a
horizontally oriented bar graph. If multiple isotopes are identified, SAM III PeakAbout II will place the most
significant isotope (highest contributing dose rate) as the top-most bar, and the remaining isotopes in
descending order to the least significant isotope (lowest contributing dose rate). Each bar will be named and
displayed with the corresponding classification color as shown in figure 4.13.
