Question

How can treating food with ionizing radiation help keep it from spoiling? UV is not very penetrating. What else could be used?

a) Ionizing radiation kills bacteria and preserves food.

b) UV penetrates sufficiently to prevent spoilage.

c) Ionizing radiation induces heat, preventing spoilage.

d) Microwave radiation is a better alternative for food preservation.

Answer 1

Treating food with ionizing radiation kills harmful bacteria and prevents spoilage. UV radiation is not as effective in preventing spoilage as ionizing radiation. Properly irradiated food is not radioactive and is safe to consume.

Step-by-step explanation:

Treating food with ionizing radiation can help keep it from spoiling by killing harmful bacteria that cause sickness. This process involves exposing the food to ionizing radiation, which destroys parasites, insect pests, and bacteria. However, it is important to note that viruses are not affected by the radiation treatment.

UV radiation is not very penetrating and may not be effective in preventing spoilage. Instead of UV radiation, ionizing radiation is used to provide a more thorough treatment. It is important to mention that properly irradiated food is not radioactive and does not pose any harm to consumers.
