Radioactivation analysis, which is a characteristic method for a non-destructive analysis, was applied for the measurement of metal components in the deposits collected mainly in Kei-yo industrial zone (Chiba Prefecture). The method was tested for intermediate and longlived radioisotopes of metals such as iron, zinc, cobalt, antimony, and scandium, and the method was found to be applicable for their measurements in addition to the determination of aluminum and manganese which was already reported in the previous paper. The geometrical variation in the amounts of these elements in the deposits was also discussed from the analytical data of these elements. The amount of iron in the deposits was influenced by the iron works near the sampling point. In addition, a large amount of zinc and cobalt was also estimated in iron-rich deposit samples, and this was considered to be due to the iron works. However, a clear relation between the amount of chromium and the iron works was not observed. The amounts of antimony and scandium determined in this study showed no geometrical fluctuations.
