Overall effect of intensity averaging on dualenergy Gamma ray ash gauge reading
GU Wen-hao
Abstract：For dual energy Gamma ray coal ash gauge, the error induced by inten sity averaging is consisted of two parts, the error caused by thickness change and by ash content change The magnitudes of the two errors are compared using app roximate analytical expressions under a simplified change pattern. Numerical cal culation shows that the error induced by thickness change is dominant. A system that regulates sampling time according to countrate level therefore can reduce this error significantly and its performance is verified by MonteCarlo simulati on.
