A 95mTc tracer with an excellent quality was prepared by a simple sublimation method after α-bombardment of niobium metal. Technetium-95m produced by the 93Nb(α,2n)95mTc reaction was separated from the niobium targets in a quartz tube by heating at 1100 °C in an oxygen gas flow. Technetium-95m sublimed as an oxide was deposited on the inner wall of the quartz tube outside an electric furnace, and then collected as a pertechnetate solution by washing with water. The ICP-MS analysis of the 95mTc solution revealed its excellent quality, compared to a 95mTc solution prepared from the same targets through a wet chemical separation method and a commercial 95mTc solution. With this tracer, the precision of ICP-MS analysis of 99Tc in environmental samples are highly improved.
