The radiation hardness graph allows you to estimate at any time which energies dominate in the gamma-ray spectrum (low, medium, high). The application includes a built-in table of hardness coefficients with reference values from ionizing radiation sources. This table helps determine which isotope best matches a specific hardness value.

The identification of isotopes is conditional. For instance, if the application determines that the radiation hardness matches the reference radiation hardness of, say, caesium-137, it only suggests that the radiation hardness is similar to that of the caesium-137 reference source.

Additionally, pseudo-determination of isotopes will not be effective if multiple radionuclides are present in the sample or gamma field.

In the graph settings, you can select which isotopes from the table will be included in the pseudo-determination and which will not. This allows you to hide rare isotopes, reducing the likelihood of incorrect determination.
