Determination of activity of Cr-51 on gamma radiation measurements

摘要

A method of determining the activity of intensive distributed -sources on the measurement of the continuous spectrum of radiation, for example the internal bremsstrahlung, is developed. The recurrent formula for reconstructing of a continuous spectrum, registered in a Ge detector, at distorting it in the detector. The method of precise measurements of the spectrum of Cr-51 internal bremsstrahlung using two point sources of low activity is described.
