Abstract

The accurate Monte Carlo (MC) simulation of scattering X-ray intensity is crucial in high energy flash radiography. On the basis of introducing the calculation method of exposure, a way for experimentally testifying the MC scattering simulation is proposed according to the main seattering source. The key is to construct a pair of correlated experiments which have the same direct component and different seattering component, so their image gray difference is related to their scattering difference X, where G can be measured experimentally and X can be calculated by MC simulation. G and are measured and calculated in three different radiography models. It is found that in all the three models the G have similar distribution with X, and the ratio G/X is nearly same as 4.95. This confirms the validation of the method and also confirms the correctness of the MC scattering simulation results.
