RADIATION MEASUREMENT SYSTEM WITH AUTOMATIC STANDARDIZATION USING A RATE FEEDBACK SIGNAL |
摘要 |
A radiation measurement system for measuring an absorption-dependent property of a material is employed in a digital process control system. The radiation measurement system includes an automatic standardization system for performing zero and source standardization and a detector for detecting the completion of each standardization mode. A rate feedback signal is derived in each standardization mode to damp the standardizing operation.
