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






2. 100 RAD






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






4. 1000 GY






5. What kind of rays does Cobalt 60 emit?






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






7. Dose required to kill bacterial spores?






8. Dose required to kill virus?






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






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






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






12. What is the half life of Cobalt 60?






13. Killing insects and eggs






14. Sprouting inhibition and

16. Dose required to kill yeast and mold?






17. Low frequency & long wave length






18. What changes take place when energy is applied?






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






20. 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






21. Gamma rays have high penetration capability






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






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






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

26. Dose required to kill a man






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






28. The common source of energy in food irradiation






29. Pasteurization of herbs and spices






30. Made into an unstable isotope by neutron bombardment






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






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






33. High frequency & short wave length
