100 Krad is the maximum permitted dose of irradiation for fruits and vegetables. Poultry may receive 3 x 100 Krad, red meat may receive 4.5 x 100 Krad, frozen meat may receive 7 x 100 Krad, spices receive 30 x 100 Krad. Therefore this calculation is a low estimate if people eat a diet containing irradiated meat and poultry as well as fruits and vegetables. 7.5 ounces is a large serving of fruit or one piece of fruit and one serving of poultry or meat.

Irradiation depletes anti-oxidant vitamins in food, which help regenerate the liver.
Even at one-tenth the concentration of radiolytic products known by the FDA to be formed by irradiation at 100 Krad, irradiation of foods in the human diet represents predictably unacceptable risks to the public's health. Finally, our estimates of URPs may be exaggerated. This rationale is based solely on an estimate of the concentration of individual URPs produced by the radiation dose to the food, and pertains even if a high proportion of the total human diet is irradiated at 100 Krad. Final report, July 1980. Calculation of number of molecules of RPs produced by 7.5 ounces of irradiated food.
