Irradiation Quiz: True or False
 

Irradiation Quiz: True or FalseOnline version

Test your knowledge on irradiation.

by DR HISHAM MOHD NOOH
1

Food irradiation preserves food with ionizing radiation without major temperature increase (“cold pasteurization”).

2

Irradiated foods do not become radioactive.

3

Gamma rays, X-rays, and electron beams are the main radiation types used.

4

Viruses are more resistant because they have less DNA compared to bacteria.

5

Cobalt-60 and Cesium-137 are common gamma ray sources.

6

Electron beams penetrate only a few centimeters, not several feet.

7

Gray (Gy) is the unit for absorbed radiation dose.

8

Low doses (≤1 kGy) inhibit sprouting in potatoes and onions.

9

High doses (>10 kGy) can sterilize food and eliminate pathogens.

10

The Radura logo must appear on irradiated retail food products.
