Abstract

Background: The accuracy for multi-parameter of long range alpha detector(LRAD) system needs to be improved.Purpose: To overcome the nonlinear effect on accuracy and have the measurements corrected.Methods: Key-parameter characteristics that affect open LRAD monitoring inside on-site pipes were analyzed.Based on the 352 groups of data from key-parameter characteristics analyzing

this paper adopted BP neural network to train and predict the measurements.Results: The predicted result has a good consistence with measurement

and the mean percentage error of the result is less than 5%.Conclusions: Using BP to predict the analysis result of LRAD has a good accurate

and besides

overcomes the impact of the system of nonlinear basically on condition of satisfying the radioactivity measurements of the law of statistical fluctuations.
