Abstract:
A method for detecting intrinsic radioactivity of radioactive samples includes: providing a sample of material to be subjected to a measurement of emission of X photons from radioactive samples, the sample being stratiform and having two main sides; placing one or more semiconductor-type or bolometer-type detectors near one or two of the two main sides of the sample, the detectors having a surface covering the whole or most of the area of the main sides; measuring the emission of X photons, respectively in the presence and in the absence of the sample, for a predetermined time interval; determining the energetic spectrum of the emission of X photons, respectively in the presence and in the absence of the sample, by measuring the number of counts produced by the emission; subtracting the measurement of the number of counts in the absence of the sample from the measurement of the number of counts in the presence of the sample, thus obtaining a useful measurement of the number of counts; estimating the X-ray detection efficiency with reference to the one or more detectors, the sample, and the energetic spectrum; determining the branching ratio (BR) of each row of the emission of X photons; determining the intrinsic radioactivity as a weighted mean value of the number of counts with respect to the measured values of detection efficiency and branching ratio within the time interval taken into account.

Claim (Index 5):
The method for detecting intrinsic radioactivity of radioactive samples according to  claim 1 , wherein said weighted mean value (Specific activity) is evaluated by means of the relation: Attivit\u00e0 \ue89e \ue89e specifica = Specific \ue89e \ue89e activity Attivit\u00e0 \ue89e \ue89e Specifica \ue89e [ Bq kg ] = CountSig t s - CountBack t B m \u00b7 \u025b \u00b7 BR where:\n CountSig represents the integral of the counts relating to each row of said emission of X photons (in the presence of the sample); \n CountBack represents the integral of the background counts within the same energy region as the X peak CountSig (in the absence of the sample); \n t S  and t B  are the sample and background measurement times; \n m is the mass of the sample to be analyzed; \n \u03b5 is said X-ray detection efficiency; \n BR is said branching ratio.
