Electron beam irradiation penetrates approximately how many inches into product packaging?

Explanation:
Electron beam irradiation delivers energy to matter before the electrons are stopped, so how deep it goes depends on the electron energy and the material's density. In typical food-irradiation setups, the energy is enough to penetrate through standard packaging and into the product by only a few inches, with 2–3 inches being a common practical depth. Beyond that, electrons lose most of their energy and the dose drops off quickly, making deeper penetration impractical for this method. The other options imply depths that would require much higher energies or a different radiation source, which isn’t how electron beams are used in packaged food irradiation.
