摘要
采用等效点源法计算结晶器液面计棒状￣（１３７）Ｃｓ源的活度分布。为扩展线性响应范围，考虑积累因子的贡献。将按设计方案制作的棒状￣（１３７）Ｃｓ源安装在１２０×１２０结晶器水套上的冷试验结果表明，测程为１１０ｍｍ，线性响应范围为６５ｍｍ，在此范围内液面高度测定值的非线性误差小于±１％。
The activity distribution of the rod-like ￣(137)Cs source in the crystallizer liquidometer is calcu-lated using the equivalent point source method.The build-up factor is considered to extend thelinear response region.The rod-like ￣(137)Cs source made according to the result of the calculation isplaced on the water jacket of the crystallizer with the dimensions of 120 mm×120 mm,and theresult of the cool experiment shows that the monitoring and the linear response regions are 110mm and 65 mm,respectively.The nonlinear deviation of the level monitoring value within linearregion is less than 1%.
