Barry, B.J.; Baker, D.B. 1996 Wood fibre density measurement with 238Pu radiation. Lower Hutt: Institute of Geological & Nuclear Sciences. Institute of Geological & Nuclear Sciences science report 96/16. [9] p.
Abstract: The form of the curve of attenuation by wood fibre of the X radiation from 238Pu has been determined. An exponential function containing a term second order in the areal density of the fibre described the curve accurately. The effect of scatter is negligible, even with an uncollimated radiation beam.
