Abstract

Abstract

Principle of flash X-ray radiography was introduced and relative mass absorption coefficient were put forward for flash radiography.Based on mono-energy model,the radiographic image was determined by path-length of object only, so the relative mass absorption coefficient could be measured from the image's optic density versus path-length curve. The relative mass absorption coefficient of tungsten was measured from the images of two triangular prism made of tungsten and Fe respectively,which is 1.23, very close to the simulating result 1.26．
