Buffon needle method of track counting
Abstract
A technique of quantitative track counting, the Buffon needle method, is advanced. It is based on random sampling of the solid state track recorder (SSTR) surface. This method extends quantitative track scanning to track densities well up into the track pileup regime. It is shown that the Buffon needle method possesses a reduced dependence upon both track density nonuniformity and track size distribution. Sources of experimental error arising in the Buffon needle method are assessed. The validity of the Buffon needle method is demonstrated down to at least the 10% uncertainty level by manual sampling of high fission track density mica SSTR observed with scanning electron microscopy.
