Through long - term test and experiment,a simplified determinantion of gross a and gross β radioactivity for coal mine drainages was suggested in this article. To raise the accuracy of the method, the characteristics of coal mine drainage were fully considered in the course of preparation of standard comparature samples. this method will greatly facilitate the clarification and utilization of coal mine drainages.
