Fate of Energy Absorbed by Polymers during Irradiation Treatment

摘要

E-beams, x-rays, and y-photons each interact with polymer molecules to eject orbital elections (1). Less than 0.015% of the total incident energy absorbed by the polymer is absorbed in this initial interaction (2). The remaining energy transfer occurs through a cascade of secondary interactions produced when a spray of high-energy ejected electrons produce many subsequent ionizations. Equation (1) illustrates this general process.
