This book is devoted to an examination of the technologies and practical implementation techniques associated with food irradiation using accelerator sources of ionizing radiation, specifically electron beams and x-rays. Introductory chapters summarize the effects of ionizing radiation on biological organisms and the organic compounds comprising foods, and gives an overview of the food irradiation process. Subsequent chapters cover the details of the electron beam and x-ray energy deposition, electron accelerator technologies, beam scanning systems, material handling systems, shielding design, and process control considerations. Important appendices cover radiation dosimetry, induced radioactivity, and ozone generation.
