THE STUDY ON ATTENUATION RULE OF X-RAY AND γ-RAY IN EXPLOSIVE

摘要

In order to test the explosive components by X-ray or 60{sup left}Co γ-ray non-destructive testing, the attenuation rules that X-ray and 60{sup left}Co γ-ray attenuate in pure and impure explosive must be known. 10 explosive columns are made for study. The data of X-ray and 60{sup left}Co γ-ray attenuatedt in explosive is studied on the basis of both theory and experiment. The X-ray and γ-ray attenuation in a certain explosive in different conditions are fitting through the regression analysis. The X-ray attenuation rule in this explosive is educed through analyzing the fitting results and the two kinds of results are compared. For γ-ray, the attenuation, which is calculated theoretically by the method of Monte Carlo (M-C), is compared with the result of experiment. The results indicate that the attenuation rule of X-ray in a certain explosive accords with cubic equation. The attenuation rule of γ-ray attenuation in pure explosive and impure explosive, which contains copper, iron and lead, is exponent equation. That the X-ray attenuation in impure explosive is obvious shows that it is feasible to test the explosive using X-ray or γ-ray.
