The number of electric pulses is recorded in counts per seconds CPS.

X-ray downhole tool with at least diagraphis targets and at least one measurement detector. The light is detected by the photomultiplier, which converts the energy into an electric pulse with amplitude proportional to the gamma-ray energy.

Isotopes with shorter halflifes mainly exist as decay products from longer lived isotopes, and, as diagraphe C14, from irradiation of the upper atmosphere. Gamma radiation spectral logging system and method for processing gamma radiation spectra. Natural radioactivity is the spontaneous decay of the atoms of certain isotopes into other isotopes. In addition, all radioactive phenomena are random in nature.
