COMPARISON OF ANALYSIS METHODS FOR THE CHARACTERISATION OF THE RADIOACTIVE CONTENT OF METALLURGICAL SLAG USED WITHIN THE EURAMET-EMRP JRP IND04 MetroMetal *

This paper presents the methods developed for the initial radioactive content description of a metallurgical slag sample to be used for the preparation of standard sources - reference materials within the EURAMET-EMRP JRP IND04 MetroMetal: Ionising radiation metrology for the metallurgical industry. The obtained results regard: - The comparative measurement of the natural radionuclide content of several samples of Romanian metallurgical slag, analysed in the Radionuclide Metrology Laboratory (RML), as compared with those used in the usual analyses performed on site by the Arcelor Mittal Company staff, collaborator of the project. - The proposed method will be applied for the measurement of the natural radionuclide content of processed Spanish metallurgical slag. - A comparison of the methods and results is presented.
