Nuclide Classes
Gamma and neutron radiation are distinguished by color in numbers, dials, and
graphs. Gamma elements are black and neutron elements are blue:
Table 2: Count Rate information
Example rate
Description
Gamma counts per second (g = Gamma)
756 gCPS
Neutron counts per second (n=neutrons)
0.02 nCPS
Various nuclide "classes" are defined by their colors, which appear as labels and as
filled-in areas in spectra.

Examples
Dangerous dose rate, detector failure
Radiation alarm threshold exceeded (gamma, neutron,
dose rate)
Calibration incomplete; detector background is lower
than stored background
Calibration done, OK to ID
