Abstract :
The techniques used to radioassay for fallout nuclides, in particular 137Cs, by gamma ray spectrometry are described. Details are given of the computer analysis of the spectra, of the internal energy standardization by the 0.511 MeV annihilation and 40K photopeaks, and of the use of smoothed background spectra. Agreement is shown between the computer method and a previously-used freehand graphical method.
