Monte Carlo simulation of the dose deposited into GAFCHROMIC® film by X-rays produced by the electron beam of PFMA-3

► Electron beam emitted backward by Plasma Focus is being studied as radiation source. ► MCNPX simulations of X-rays produced by electrons impinging on a 50 μm brass foil. ► The spectrum is analysed to estimate the penetration in and dose to human tissue. ► Doses determined from the simulations are compared with experimental values.
