PREDICTING DEVICE FOR CONCENTRATION OF AIR CONTAMINATION IN WORKING ENVIRONMENT

摘要

PURPOSE:To enable more close prediction to the true values by storing each concentration value of air contamination obtained through working experience in periodical inspection works and the like of unclear power stations, to a data bank, and by applying the values to predict the concentration of air contamination in wider working conditions. CONSTITUTION:At a data bank 1, each concentration value of air contamination obtained through working experience in periodical inspection works and the like of unclear power stations, are stored along with element data such as radiation source conditions and content of the works in the works. In case of prediction of the concentration value of air contamination in newly planned works, information regarding the elements to affect the concentration of air contamination, that is to say, radiation source information indicating the source condition in the works, information of working environment indicating extent of affection to the radiation source by the works and information on evaluation point thereof, are input from an input device 2. A deduction engine 3 extracts the data corresponding to the input informations from the data bank 1 and thereby statistically treats all the concentration values data of air contamination in order to obtain the predicted values in the object works and finally outputs the values through an output device 4.
