QR Challenge: Radiation Biology Final Review

Created using the ClassTools QR Treasure Hunt Generator

Teacher Notes

A. Prior to the lesson:

1. Arrange students into groups. Each group needs at least ONE person who has a mobile device.

2. If their phone camera doesn't automatically detect and decode QR codes, ask students to

• Download a QR reader (e.g. I-Nigma | NeoReader | Kaywa) onto their mobile devices
• Bring these devices into the lesson.

3. Print out the QR codes.

4. Cut them out and place them around your class / school.

---

B. The lesson:

1. Give each group a clipboard and a piece of paper so they can write down the decoded questions and their answers to them.

2. Explain to the students that the codes are hidden around the school. Each team will get ONE point for each question they correctly decode and copy down onto their sheet, and a further TWO points if they can then provide the correct answer and write this down underneath the question.

3. Away they go! The winner is the first team to return with the most correct answers in the time available. This could be within a lesson, or during a lunchbreak, or even over several days!

3. True of false. RNA contains deoxyribose sugar.	True
4. What are the 3 types of RNA?	tRNA, mRNA, and rRNA
5. a large D subscript o represents (radiosensitivity/radioresistance)	radioresistance
6. In a linear nonthreshold dose response curve, the curve exhibits a (deterministic/stochastic) effect.	stochastic
7. True or false. In a sigmoid, threshold dose-response curve, there is no recovery associated with lower doses.	false. There is partial recovery. Bushong 484
8. True or false. In a sigmoid, threshold dose-response curve, usually there is an upward point at the highest dose.	false. There is a downward turning point.
9. in a sigmoid, threshold dose-response curve, the curve exhibits (deterministic/stochastic) behavior.	deterministic
10. True or false. In a sigmoid, threshold dose-response curve, you have to reach a certain dose before you will get a specific effect.	true
11. True or false. Cancer is a long term somatic effect.	true
12. True or false. Cataracts are a long term somatic effect.	true.
13. True or false. Life span shortening is a long term somatic effect.	true
14. What are the three dose modifying factors of late radiation effects? (hint one is dose)	dose, dose rate, and species variation.
15. What are the 3 stage of lethality or response? (think whole body exposure, syndrome stages)	prodromal, latent, manifest.
16. Why do hydrogen and hydroxyl ions present minimal danger of biologic damage?	They can easily recombine to form a water molecule.
17. The measure of cell radiosensitivity on a survival is curve is the definition of what?	Do
18. The dose of radiation that will kill 63% of the irradiated population is the definition of what?	D37
19. The maximum sublethal damage, measured on the shoulder of the cell survival curve is the definition of what?	Dq
20. Hemopoietic syndrome is an (early/late) effect.	early
21. Erythema is an (early/late) effect.	early
22. Childhood malignancy is an (early/late) effect.	late
23. Bone cancer is an (early/late) effect.	late
24. Nausea and vomiting are an (early/late) effect.	early
25. Prenatal death is an (early/late) effect.	early
26. Cataracts are an (early/late) effect.	late
27. As radiosensitivity increases, LET (increases/decreases)	increases
28. As the mass of a particles increases, LET (increases/decreases)	increases
29. As LET increases, RBE (increases/decreases)	increases
30. As radiosensitivity increases, OER (increases/decreases)	increases
31. Radioprotectors (increase/decrease) sensitivity of the tissues.	decrease
32. As dose rate decreases, RBE (increases/decreases)	decreases

38. Death occurs within hours to 3 days (Hematopoietic/GI/CNS)	CNS
39. Death occurs within 4-10 days (Hematopoietic/GI/CNS)	GI
40. Decreased blood count is a key factor (Hematopoietic/GI/CNS)	hematopoietic
41. Drastic decrease in fluids (Hematopoietic/GI/CNS)	GI
42. Infection and death of crypt cells are a key factor (Hematopoietic/GI/CNS)	GI
43. Burning sensation of the skin (Hematopoietic/GI/CNS)	/CNS
