Question

Select the statements about ionizing radiation that are true. (NOTE: Please change all question marks to checkmarks for correct answers or empty boxes for incorrect answers.) It causes food to become toxic. It can be used to reduce spoilage organisms on food. It may cause changes that make food carcinogenic. It can be used to sterilize medications. It can be used to sterilize medical equipment. It causes food to become radioactive.

Answer 1

Statements that are true:

• It can be used to reduce spoilage organisms on food.
• It can be used to sterilize medical equipment.

Explanations:

Ionizing radiations (i.e, gamma irradiation, electron irradiation and x-ray irradiation) causes the death of micro-organisms which are present in food and thus cause food spoilage. Therefore, Ionizing radiation reduces food spoilage. Also, the micro-organisms present in the medical equipment can also be eliminated and thus, it is also widely used for sterilization purposes.

The other statements are false.

Explanations:

Ionizing radiations (i.e, gamma irradiation, electron irradiation and x-ray irradiation) does not affect food items to cause carcinogenic effects or induces radioactivity in it. It has no toxic effects on food. Also, medications are not sterilized by inducing ionization radiation.
