FIELD: measuring equipment.
SUBSTANCE: using for measuring the energy spectrum. Essence of invention consists in the fact that in one embodiment of the invention, the method includes transmitting electromagnetic radiation through the fluid and obtaining a portion of the electromagnetic radiation by the detector. This method also includes measuring the energy spectrum of a portion of the electromagnetic radiation produced by the detector, and application of the measured energy spectrum and the physical model of the detector response to electromagnetic radiation to reveal the intensity of the signals for the discrete energy levels of a part of the electromagnetic radiation obtained by the detector. In addition, additional systems, devices and methods are disclosed.
EFFECT: ensuring the possibility of reliable determination of signal strength for different types of sources.
