The results of this work suggest reconsidering the risk due to alpha emitters present in the packaging or in the constituent materials of power devices in causing SEB failures. Finally, given the simplicity and economy of the procedure, radioactive alpha sources might come into consideration to be...
In this paper it is shown experimentally that single alpha particles emitted from radioactive sources can produce Single Event Burnout failures in silicon and silicon carbide power devices at blocking bias levels below 90 % of the breakdown voltage. Silicon carbide devices have been shown to be mor...

Particulate matter (PM) emitted during laser additive manufacturing with stainless steel powder materials has been studied in detail. Three different additive manufacturing techniques were studied: selective laser melting, direct metal deposition and laser cladding. Gas flow and temperature fields accompanying...
“NRC”) has not declared any other material as SNM. SNM is only mildly radioactive, but it includes some fissile material, uranium-233, uranium-235, and plutonium-239, that, in concentrated form, can be the primary ingredients of nuclear explosives. These materials, in quantities greater ...
