End-Term Exam: Legal Inquiry and Evaluation (LRA 215)
1.As (LET) , the (RBE) .: Increases, Increases
2.Tissues is radiosensitive under high oxygen conditions and ra-
diosensitive under hypoxic conditions: More, Less
3.Tissues that are with a metabolic rate are more radiosensitive.-
: Immature, High
4.If a response to radiation is expected, no matter how small the dose,
then that dose-response is .: Nonthreshold
5.A response to radiation is directly proportional to the dose received.
: Linear
6.The low of states that the radiosensitivity of living tissue is a func-
tion of the metabolism and maturation of the tissue.: Bergonie and
Tribondeau
7.Humans are most radiosensitive during .: Fetal stages
8.Radiation induced genetic damage follows a dose-response
rela- tionship.: Linear - Nonthreshold
9.The (RBE) of diagnostic x-rays is equal to .: 1
10.The (LET) of diagnostic x-rays is_____keV/ym.: 3.0
11. is a measure of the rate that energy is transferred from
ionizing radiation to soft tissue.: (LET)
12.Which dose-response relationship can follow a sigmoid curve?: Nonlinea
- Threshold
13.Which of the following is considered the most radiosensitive?: Fetus
14. How does oxygen retention affect cell radiosensitivity?: Increases
radiosen- sitivity
15.Which of the following is a graphical representation of the relationship
between radiation dose and observed response, in which any dose may
have a potential effect, and there is a direct relationship between dose
and effect?: Linear, Nonthreshold done-response curve
16. refers to the enhancement of therapeutic or detrimental effect of
ionizing radiation due to the presence of oxygen.: Oxygen Enhancement
Ratio (OER)
17. is a measure of the energy transferred to material as an ionizing
particle travels through it. This measure is used to quantify the age effects
of ionizing radiation on biological specimens.: Linear Energy Transfer
(LET)
18.Cells which are considered highly radiosensitive include::
