The improvements are as follows: increasing the efficiency of the detector to 11%; reducing the measurement time by simultaneously measuring and irradiating the samples; installing an automatic device for changing the samples; improving the automatic control and the irradiation safe-guards. Now the detection limit for natural uranium is about 0.01ppm. The time for measuring one sample is less than one minute. It can determine six thousand samples per month. The cost of the analysis is more inexpensive
