Gammaspectrometric techniques for identification, characterisation and quantification include both high and low resolution methods. The aim of this work has been to study the quality in the identification of radionuclides with low resolution techniques. The study has included radionuclides used in industrial and medical applications and also special nuclear material (SNM). In the study three low resolution detectors have been used. They are icx identiFINDER, Exploranium GR-135, both with NaI(Tl) and icx identi- FINDER with LaBr3(Ce). In some cases reference spectra with the high resolution Ortec Detective EX have been taken. With each of the three low resolution detectors measurements have been taken of the different nuclides. After the measurements the instruments identify-function have been used to give a nuclide proposal. The instruments have internal nuclide libraries and a presumption for a correct identification is that the specific radionuclide is in the library chosen. To demonstrate the importance of this the identification was made with different libraries in some cases. The result shows some examples where the identification was wrong and where different choices of libraries gave different answers. The results indicate that the instruments do not use all the spectral data when evaluating and also that despite the better resolution in the LaBr3 detector compared to the NaI, the identification results are not noticeably better. Based on the results our opinion is that a user must either has the expertknowledge to, in a critical way, evaluate and analyse the results and spectra given by the instrument, or have access to a competent reach-back organisation.
