Non-destructive measurement using back scatter of neutron

We present the method for non-destructive measuring the inside scale of sealed container. We have constructed the devices by the use of proposed method, and we have inspected the most suitable location with object of measurement, when scale is measured. And we showed that this devices was capable of measuring water level. The result of the evaluation experiment, devices was capable of measuring thickness of clay, and difference of measuring location had a significant effect on measuring result. We developed the application of analysis and diagnosis, and water level was measured by using devices, the fine data within 88.9% correct answer rate was obtained.
