In order to test the explosive components by X-ray or 60 Co ? -ray non-destructive
testing, the attenuation rules that X-ray and 60 Co ? -ray attenuate in pure and impure explosive
must be known.
10 explosive columns are made for study. The data of X-ray and 60Co ? -ray attenuatedt in
explosive is studied on the basis of both theory and experiment. The X-ray and ? -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 ? -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 ? -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 ? -ray.
