Abstract

^44gSc was produced by 16 MeV proton irradiation of unenriched calcium metal with radionuclidic purity greater than 95%. The thick target yield at saturation for ^44gSc was ²¹³MBq/μA, dwarfing the yields of contaminants ⁴³Sc,^44mSc, ⁴⁷Sc and ⁴⁸Sc for practical bombardment times of 1–2 h. Scandium was isolated from the dissolved calcium target by filtration, and reconstituted in small volumes of dilute HCl. Reactions with the chelate 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA) indicated a reactivity of View the MathML source54±14Gbq/μmol at end-of-bombardment.
