中文摘要	A remarkable systemic error which was unknown in past long time has been indicated. The error appears in the calibration methods of determining activity of /sup 238/U is used with gamma -spectrometer with high resolution. When the gamma -ray of 92.6 keV as the characteristic radiation from /sup 238/U is used to determine the activity of /sup 238/U in natural environment samples, the disturbing radiation produced by external excitation (or called outer sourcing X-ray radiation) is the main problem. Because the X-ray intensity is changed with many indefinite factors, it is advised that the calibration methods should be put away. As the influence of the systemic errors has been left in some past research papers, the authors suggest that the data from those papers should be cited carefully and if possible the data ought to be re-determined.
