Systems and methods for improved analysis of electromagnetic spectra

A system comprising:

• at least one computer hardware processor, and
• at least one non-transitory computer readable storage medium storing processor-executable instructions that, when executed by the at least one computer hardware processor, cause the at least one computer hardware processor to perform a method comprising:
• identifying, using radiation spectroscopy information obtained over a measurement time period, one or more energies associated with electromagnetic radiation emitted by a measured material by:
• dividing the measurement time period into two or more subperiods;
• identifying, for each of the two or more subperiods, measured radiation energies in a subset of the radiation spectroscopy information associated with one of the two or more subperiods;
• and
• selecting, from the identified radiation energies for each of the two or more subperiods, radiation energies identified in at least two of the two or more subperiods;
• and
• identifying, using the selected radiation energies, one or more radioisotopes present in a composition of the material.
