Comparison of Experimental Data Versus Computer Modeling of a Radiation Detecting Personnel Safety System Ion Chamber


The purpose of this paper is to present experimental data to demonstrate the validity of a computer-designed safety system, based on an ionization chamber, used in the detection of electron beams. The first section of the paper describes the safety system, from the radiation producing beam line to the electronic safety system monitoring modules. The second section of the paper describes the radiation simulation modeling program, EGS4. This computer code predicts where the beam-generated radiation, commonly known as a "shower," deposits its energy after colliding with beam line devices (e.g., collimators, stoppers, etc.). This allows for the best placement of safety devices to protect these beam line devices.
