摘要

A fundamental investigation of the PIXE method applied to ^e?ent of trace elements in wood samples, is described in this work. Yields ofthe elements added to a sugi (Cryptomeria japonica D. Don) specimen, were almost constant after they were bombarded with radiation up to_600(xC Yields of certain elements in the early wood and the late wood mthej annual ring of the sugi were compared. The yields of Ca, Cu, Zn, RbancISr in the late wood were the same or slighdy higher than those m the eari wood, but Fe and Mn yields in the late wood were higher than.to*^m fe early wood. The concentration profiles of Ca, Mn, Fe, Zn and Sr a radial direction in the stem of the sugi were also determined.
