Title: Double activation analysis: a new application of established techniques. [/sup 56/Mn]

Abstract

Water samples show a drop from 9.8 ..mu..g Mn/mL immediately after /sup 55/Mn-/sup 56/Mn addition to 1.8 ..mu..g Mn/mL after 6 h. Root samples show an increase from 750 ..mu..g Mn/g soon after introduction of the tracers to 1400 ..mu..g Mn/g after 2 h, achieving a maximum of over 4000 ..mu..g at 10 h. The initial activation of stable Mn provided radiomanganese-/sup 56/Mn for immediate tracer study. The second activation (double activation) activated some of the stable Mn which escaped the initial activation, providing radiomanganese-/sup 56/Mn for long-term tracer study. The over-lapping data points shown as open and closed circles and the continuation of data points for up to 20 days establish the usefulness of the double activation analysis technique for short-term and long-term tracer studies.
