Abstract

As a radiopharmaceutical, the use of 59Fe is classified as a high pharmaceutical risk product. Therefore, a standard reference for activity measurement of 59Fe is necessary to ensure its metrological aspect. This paper describes an alternative method for primary activity determination of 59Fe for establishing a standard reference. The 59Fe solution was prepared using two different cocktails and measured by the 4-phi-beta(LS)-gamma counting system using a digital anti-coincidence-counting method with emulated live-time of the extending dead-time. A final activity results at the reference time for the two samples series are (473.32  2.55) kBq/g and (477.14  2.42) kBq/g with quoted uncertainty evaluated at k = 1. The final activity was compared to the value obtained from the other two coincidence counting method and found to be in a good agreement within its uncertainty value.
