Description
This study describes the development and experimental application of two types of suspended sediment gauges by using nuclear technique. A radioactive source Am-241 and radiation detecting system are used to measure suspended sediment concentration in this experiment. The distance between the radioactive source and detecting probe was set at 22.5 cm, while the diameter of the collimated source was 7.0 mm. From the experiment, the factor of measuring error has been analysed and a calibration curve of the count-rate and sediment concentration has been established. The range of measurement of the gauge is about 0 - 2.34 u g/cc, high enough for most equatorial stream flow. New suspended sediment gauge system also being proposed for shallow and deep water
