What type of food irradiation is ideal for processing whole chickens and turkeys?

• A. Electron Beam
• B. X-rays
• C. Gamma Rays
• D. Ultraviolet

Answer: (B)

For large, whole poultry, you need an irradiation method that can penetrate through the entire carcass and deliver a uniform dose. Ultraviolet can only disinfect surfaces, so it won’t reach inside thick birds. Electron beams deposit most of their energy near the surface and don’t penetrate deeply enough through bones and dense tissue, leading to uneven treatment. Gamma rays do penetrate well, but relying on radioactive sources brings ongoing safety, regulatory, and logistics challenges.

X-rays generated by linear accelerators provide deep, uniform penetration similar to gamma rays, but without needing radioactive materials on-site. They can be turned on and off as needed and are well suited to processing bulky items like whole chickens and turkeys on a conveyor, ensuring the interior tissues receive the intended dose. That combination of effective penetration and flexible, clean operation makes X-rays ideal for this application.
