Instructions:
  • Answer 33 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Made into an unstable isotope by neutron bombardment






2. The quantity of radiation that results in the absorption of 100 ergs per gram of food






3. The food category - the purpose of irradiation - and the dose permitted in KGY






4. Dose required to kill a man






5. Food treated with ionizing radiation (IR) is said to be






6. Utilizing (IR) to achieve biological stability of food by inhibiting or minimizing spoilage reactions






7. What changes take place when energy is applied?






8. Determines how far the MWs penetrate into the food and it is affected by the above two parameters plus others






9. What kind of rays does Cobalt 60 emit?






10. Sprouting inhibition and






11. These rays have no penetration depth hence it will only achieve surface inactivation of microorganisms






12. Traditional unit of measuring the amount of energy absorbed by food






13. Determines the amount of heat generated from the absorbed energy






14. 100 RAD

21. The common source of energy in food irradiation






22. 1000 GY






23. High frequency & short wave length






24. Killing insects and eggs






25. Dose required to kill virus?






26. Indirect Effect- ionization of molecules that produces ion pairs (by knocking off an electron) and free radicals (by breaking bonds) result in chemical reactions that interrupt biological functions






27. -the more complex the biological system is the less amount of IR required to induce changes






28. Determines the affinity of a food system to absorb microwaves






29. Dose required to kill bacterial spores?






30. Direct Effect- a bullet-like effect with high energy particles impacting the vital parts of the cell






31. Which waves vary in frequency and are closer to Radio waves frequencies






32. Is also used in limited extent in food irradiation.






33. Low frequency & long wave length
