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. Dose required to kill insects?






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






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






5. Dose required to kill a man






6. Pasteurization of herbs and spices






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






8. Dose required to kill bacterial spores?






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






10. Dose required to kill virus?






11. 1000 GY






12. Dose required to kill yeast and mold?






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






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






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






16. 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

18. 100 RAD






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






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






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






22. The common source of energy in food irradiation






23. Sprouting inhibition and






24. What is the half life of Cobalt 60?






25. High frequency & short wave length






26. What changes take place when energy is applied?






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






28. What kind of rays does Cobalt 60 emit?






29. Gamma rays have high penetration capability






30. Killing insects and eggs






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






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






33. Made into an unstable isotope by neutron bombardment
