Abstract
Technetium volatilization during preconcentration of deposition samples (containing rain and solid matter) with different concentrations of elements was studied by tracer experiments. During evaporation of the samples to dryness, hardly and Tc contained in them was volatilized. However, when the same evaporation experiment was carried out with a deionized water sample, unexpected behaviour of Tc was observed, i.e. a part of the Tc was lost during preparation of the dried-up sample. The major elements, which are present in large amounts in deposition samples, affected Tc stability.
