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. Low frequency & long wave length






2. 1000 GY






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






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






5. Made into an unstable isotope by neutron bombardment






6. Dose required to kill insects?






7. High frequency & short wave length






8. Dose required to kill a man






9. Dose required to kill bacterial spores?






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






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






12. Gamma rays have high penetration capability






13. What is the half life of Cobalt 60?






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






15. The common source of energy in food irradiation






16. Sprouting inhibition and






17. What kind of rays does Cobalt 60 emit?






18. Pasteurization of herbs and spices






19. What changes take place when energy is applied?






20. Dose required to kill yeast and mold?






21. Killing insects and eggs






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






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






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






25. 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






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






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






28. 100 RAD






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






30. Dose required to kill virus?






31. Describes a continuous range of radiation energy having an electric and a magnetic component






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






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