|
True of false. RNA contains uracil. | True.
| True of false. RNA contains deoxyribose sugar. | True
| What are the 3 types of RNA? | tRNA, mRNA, and rRNA
| a large D subscript o represents (radiosensitivity/radioresistance) | radioresistance
| In a linear nonthreshold dose response curve, the curve exhibits a (deterministic/stochastic) effect. | stochastic
| 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
| 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.
| in a sigmoid, threshold dose-response curve, the curve exhibits (deterministic/stochastic) behavior. | deterministic
| 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
| True or false. Cancer is a long term somatic effect. | true
| True or false. Cataracts are a long term somatic effect. | true.
| True or false. Life span shortening is a long term somatic effect. | true
| What are the three dose modifying factors of late radiation effects? (hint one is dose) | dose, dose rate, and species variation.
| What are the 3 stage of lethality or response? (think whole body exposure, syndrome stages) | prodromal, latent, manifest.
| Why do hydrogen and hydroxyl ions present minimal danger of biologic damage? | They can easily recombine to form a water molecule.
| The measure of cell radiosensitivity on a survival is curve is the definition of what? | Do
| The dose of radiation that will kill 63% of the irradiated population is the definition of what? | D37
| The maximum sublethal damage, measured on the shoulder of the cell survival curve is the definition of what? | Dq
| Hemopoietic syndrome is an (early/late) effect. | early
| Erythema is an (early/late) effect. | early
| Childhood malignancy is an (early/late) effect. | late
| Bone cancer is an (early/late) effect. | late
| Nausea and vomiting are an (early/late) effect. | early
| Prenatal death is an (early/late) effect. | early
| Cataracts are an (early/late) effect. | late
| As radiosensitivity increases, LET (increases/decreases) | increases
| As the mass of a particles increases, LET (increases/decreases) | increases
| As LET increases, RBE (increases/decreases) | increases
| As radiosensitivity increases, OER (increases/decreases) | increases
| Radioprotectors (increase/decrease) sensitivity of the tissues. | decrease
| As dose rate decreases, RBE (increases/decreases) | decreases
| As the extrapolation number decreases, the cell's radiosensitivity (increases/decreases). | increases. The extrapolation number measures the cell's capacity to withstand damage.

| Death occurs within 4-10 days (Hematopoietic/GI/CNS) | GI
| Decreased blood count is a key factor (Hematopoietic/GI/CNS) | hematopoietic
| Drastic decrease in fluids (Hematopoietic/GI/CNS) | GI
| Infection and death of crypt cells are a key factor (Hematopoietic/GI/CNS) | GI
| Burning sensation of the skin (Hematopoietic/GI/CNS) | /CNS |
