Large Sample Neutron Activation Analysis: Developments and Perspectives Open
Most of the available analytical techniques do not comply with the need for direct trace element analysis of samples of mass exceeding the order of grams. Instead sub-sampling methods are used to obtain representative sampling of the studi…

Distribution of radionuclides in an iron calibration standard for a free release measurement facility Open
A Europallet-sized calibration standard composed of 12 grey cast iron tubes contaminated with (60)Co and (110m)Ag with a mass of 246kg was developed. As the tubes were produced through centrifugal casting it was of particular concern to st…
