Uniformity is very important for radioactive reference material and should be solved in the process of preparation.Radioactive hot spot is exact the crucial factor for the kind of reference soil material which in the form of powder.Hot spot is not easy to be found,but it can cause great error in the measurement.So it is necessary to remove hot spots in the preparation process.
