专利汇可以提供Radiation measuring apparatus专利检索,专利查询,专利分析的服务。并且PURPOSE: To prevent statistical errors from changing with measurement values by making the radiations etc. applied to a detector to a fixed quantity through feedback controlling.
CONSTITUTION: Radiation exposure from a radiation generator 11 causes the sample 3 to emit radiation or light according to its composition. These are then detected with a detector 5 and the characteristics of the sample 3 are displayed on indicator by way of a does rate meter 7. In this case, the output of the dose rate meter 7 is so controlled that the input to the detector 5 becomes of a fixed quantity by feedback-controlling the device 11 through a feedback circuit 19. Hence, the occurrence of statistical errors corresponding to the measurement values is prevented and accurate measurement is accomplished.
