ㆍprocessing of alpha-spectra of both thin and thick sources;

ㆍconsideration of thin structure of alpha-spectra, parametrical description of the line shape;

ㆍconsideration of conversion electrons contribution. It is required if the ratio of detectors parameters to the distance

   between source and detector is small;

ㆍregistration efficiency calculation;

ㆍactivity calculation by the inserted label. It allows to take into account the a priori information for results specification;

ㆍcalculation of the radiochemical yield is calculated as the ratio between the amount of the nuclide material in the

   measured sample and theamount of this nuclide material, added to the probe).
