Application of mathematical modeling technologies to industrial radiation processing

The application of Monte Carlo and point kernel techniques to absorbed dose calculation has historically been limited to shielding calculations associ ated with reactor, irradiator and spacecraft design. The evolution of micro processors and associated operating systems, coupled with state-of-the-art I-D, 2-D and 3-D direct measurement of dose distribution allow the industri al radiation processing facility to develop source construction and applica tion strategies for use in the irradiation of commercial goods. A series of experimental versus computational exercises are reviewed covering gamma, e lectron beam and X-ray applications. The ongoing development process associ ated with the generation of standard practices is addressed. Finally, the a uthors explore the use of multiple microprocessor-based approaches to perfo rm complex Monte Carlo and point kernel calculations, and broach the subjec t of 'radiation processing at 10 GHz'.
