Barry, B.J.; Baker, D.B. 1996 Density profiling of thin samples . Lower Hutt: Institute of Geological & Nuclear Sciences Institute of Geological & Nuclear Sciences science report 96/21 [11] p.
Abstract: Density profiles of fibre and filler through cardboard samples have been determined by attenuation measurements of a dual energy beam from a radioactive source. Improvements to the design of such a profiler for thin card are described. Results are presented for a suite of previously studied samples. Features of the measurements are discussed along with possible use of deconvolution techniques to improve the resolution. (auth)
