Claim:
1. A method comprising: depositing a controlled stream of a biomass material, in particulate form, on a covered vibratory conveyor using a spreader; exposing the biomass material on the vibratory conveyor to ionizing radiation in the form of a scanning electron beam through an opening in the conveyor cover, and during exposure to the electron beam, causing the vibratory conveyor to vibrate the particles of the biomass material during irradiation, wherein the biomass material defines a substantially uniform average bed thickness across the width of the vibratory conveyor of between about 0.125 to 0.5 inches on the conveyor as it is being exposed to the ionizing radiation.
