   Summary: The behaviour of technetium in the geosphere is important in nuclear fuel waste management studies because this manmade element has a long half-life and, under ambient conditions in the laboratory, is not readily sorbed on geological materials. Fourier transform infrared spectroscopy studies have shown conclusively that the reaction between TeO; and Fe304 at room temperature occurs via a surface reduction of TcO4 to TcO2, the latter being precipitated at the Fe304 surface. These results confirm that technetium can be contained effectively by magnetite in the geosphere, provided reducing conditions can be maintained.
