In order to improve the accuracy and detection efficiency, reference uranium particles are needed that are similar to the particles found in swipes. The method developed at IRMM is based on the controlled hydrolysis of UF6 with a certified isotopic composition. The morphology and composition of the particles was dependent on the relative humidity of the air, the exposure to ultraviolet light and the time elapsed after formation. The particles will be used for nuclear signatures inter-laboratory measurement evaluation programs (NUSIMEP). }, title = {The Preparation of Uranium Oxyfluoride Particles for Inter-Laboratory Measurement Campaigns}, url = {http://www.inmm.org}, volume = {}, number = {}, journal = {}, pages = {1-8}, issn = {}, publisher = {Institute for Nuclear Materials Management (INMM)}, doi = {} }
