| Zusammenfassung | A new large volume metal reference standard has been developed. The intended use is for calibration of free release radioactivity measurement systems and is made up of cast iron tubes placed inside a box of the size of a Euro-pallet (80 × 120 cm.). The tubes contain certified activity concentrations of 60Co, (0.290 ± 0.006) Bq/g-1) and 110Am (3.05 ± 0.09) Bq/g-1 (Reference date: September 30, 2013). They were produced using centrifugal casting from a smelt into which 60Co was first added and then one piece of neutron irradiated silver wire was progressively diluted.The iron castings were machined to the desirable dimensions. The final material consists of 12 iron tubes of 20 cm outer diameter, 17.6 cm inner diameter, 40 cm length/height and 245.9 kg total mass. This paper describes the reference standard and the process of obtaining the reference activity values. |
