“…Spiking was carried out with a 226 Ra standard solution following an immersion procedure similar to that described by Shakhashiro et al [13]. Full details of the preparation, spiking and homogeneity testing by gammaray spectrometry are described elsewhere [14]. Figure 3 presents a typical source.…”

Abstract. Every year millions tons of steel are produced worldwide from recycled scrap loads. Although the detection systems in the steelworks prevent most orphan radioactive sources from entering the furnace, there is still the possibility of accidentally melting a radioactive source. The MetroMetal project, carried out in the frame of the European Metrology Research Programme (EMRP), addresses this problem by studying the existing measurement systems, developing sets of reference sources in various matrices (cast steel, slag, fume dust) and proposing new detection instruments. This paper presents the key lines of the project and describes the preparation of radioactive sources as well as the intercomparison exercises used to test the calibration and correction methods proposed within the project.
