Report of APMP comparison of the activity measurements of Fe-59 (APMP.RI(II)-K2.Fe-59)

The international comparison of activity measurements of 59Fe, APMP.RI(II)-K2.Fe-59, was carried out within the framework of the Asia-Pacific Metrology Programme (APMP). Nine institutes took part in the comparison, and eight institutes of them undertook absolute measurements. One ampoule prepared using the same radioactive solution as that used in the comparison was sent to the BIPM/SIR in order to link the comparison to the BIPM key comparison reference value (KCRV).
