Experimental Work on Ruthenium Releases

Aim: To quantify the amount of ruthenium released from a non-radioactive solid. Overview of Task: The quantity of ruthenium that is released to the gas phase from a solid that is heated in the region 200-650 °C is to be measured. Four different solids will be assessed. Three of the solids will consist of a large number of element oxides and element nitrates from across the periodic table. Ruthenium is present in the solid at around 1% by elemental mass, but the precise speciation is not known. However, the rutheni...
