Question

some foods undergo sterilization in order to kill bacteria living in and on the food. what type of radiation is used in sterilization to kill bacteria?
a. alpha
b. beta
c. fission
d. gamma

Explanation:

• Alpha radiation has low penetration and is not suitable for food sterilization as it can't reach internal bacteria well.
• Beta radiation also has limited penetration and may not effectively kill bacteria throughout the food.
• Fission is a nuclear reaction (splitting of atoms), not a type of radiation used for food sterilization.
• Gamma radiation has high penetration power, can kill bacteria (and other microorganisms) in food by damaging their DNA, and is commonly used in food sterilization processes.

Answer:

D. Gamma
