Abstract

The application of Monte Carlo and point kernel techniques to absorbed dose calculation has historically been limited to shielding calculations associated with reactor, irradiator and spacecraft design. The evolution of microprocessors and associated operating systems, coupled with state-of-the-art 1-D, 2-D and 3-D direct measurement of dose distribution allow the industrial radiation processing facility to develop source construction and application strategies for use in the irradiation of commercial goods. A series of experimental versus computational exercises are reviewed covering gamma, electron beam and X-ray applications. The ongoing development process associated with the generation of standard practices is addressed. Finally, the authors explore the use of multiple microprocessor-based approaches to perform complex Monte Carlo and point kernel calculations, and broach the subject of ‘radiation processing at 10 GHz’.
