Fabrication of Sealed Source Scandium-46 (46sc) As an Alternative Calibration Standard

Cobalt-60 is usually used for calibration standard that nowadays, it hard to fabricated. This research aims to fabricate of Sealed Source 46Sc as alternative Calibration Standard. Sealed source 46Sc radioactivity was 1.17 ± 0.08 µCi, sealed with an aluminum label. Radiation exposure on the surface opened container is 19.27 ± 0.09 µSv/h, a closed is 10.78 ± 0.15 µSv/h and the distance of 1 m from an open container is 4.40 ± 0.04 µSv/h whereas closed has 2.40 ± 0.04 µSv/h. Multi-channel analyzer γ-spectrometry showed the 46Sc gamma spectrum similar with characteristics from standard 60Co source.
