We are developing a new, well spatially resolved (millimetric resolution), high sensitivity and high quantum detectivity, large size pixellized CdTe(Zn) camera for high energy (> 1 MeV) flash radiography applications. Energy deposition Monte Carlo si

We demonstrate that high porosity anodically porous silicon is radioluminescent. Interests of this study are double. Firstly: is the construction of porous silicon X-rays detectors (imagers) possible? Secondly: is it necessary to protect silicon poro

Quantitative measurement of X irradiated object requires calibration of the film. When the scattered radiation level is low enough, we suggest calibration of the film by means of a stepwedged series of holes carved out in the collimator periphery. In

An analytical model of the scattered radiation obtained in flash radiography is described. Scatter is related to the areal masses of the object through a function depending on the energy and the object-to-receptor distance. Some particular cases are

The purpose of this paper is a new application of the already known in optics half-filter bootstrap method in the frame of radiography in order to calibrate X film pack detectors. The key to this method is the practical calculation of a "grey filter"
