Response calibration of a PGNAA setup utilizing silica fume cement concrete specimens

Abstract

Monte carlo simulations were conducted to calibrate the response of an acceleratorbased PGNAA setup for determining the silicon concentration using silica fume cement concrete specimens the prompt gammaray yield was initially calculated as a function of specimen dimension to determine its optimum radius and length It was then calculated from cement concrete specimens containing 0 to 20 % silica fume by weight of portland cement The results of the calculations show a linear response of gammaray for silicon with increasing concentration of silica fume in the concrete specimens
