LRA 215 Final review
1. Tissues is radiosensitive under high oxygen condi- More, Less
tions and radiosensitive under hypoxic conditions
2. Tissues that are with a metabolic rate Immature, High
are more radiosensitive.
3. If a response to radiation is expected, no
Nonthreshold
matter how small the dose, then that dose-
response is .
4. A response to radiation is directly proportional to Linear
the dose received.
5. The law of states that the radiosensitivity Bergonie and
of liv- ing tissue is a function of the metabolism Tribondeau
and matura- tion of the tissue.
6. Humans are most radiosensitive during . Fetal stages
7. Radiation induced genetic damage follows a Linear - Nonthreshold
dose-response relationship.
8. The (RBE) of diagnostic x-rays is equal to . 1
9. The (LET) of diagnostic x-rays is keV/ym. 3.0
10. is a measure of the rate that energy is
trans- ferred from ionizing radiation to soft Linear energy transfer
tissue. (LET)
11. Which dose-response relationship can follow Nonlinear - Threshold
a sig- moid curve?
12. Which of the following is considered the Fetus
most ra- diosensitive?

14. Which of the following is a graphical representation of Linear,
Nonthreshold the relationship between radiation dose and
observed done-response curve response, in which any dose
may have a potential ef-
fect, and there is a direct relationship between
dose and effect?
15. refers to the enhancement of therapeutic or Oxygen

detrimental effect of ionizing radiation due to the pres- tio (OER)
ence of oxygen.
16. is a measure of the energy transferred Linear Energy
to ma- terial as an ionizing particle travels Transfer (LET)
through it. This measure is used to quantify
the age effects of ionizing radiation on
biological specimens.
Lymphocytes
17. Cells which are considered highly
radiosensitive in- clude:
Spermatogonia
Erythroblast
Intestinal crypt cells
18. A cytogenetic analysis of chromosomes may be accom- c. Karyotype
plished through the use of a chromosome map.
This map is called a:
a. Chromosomagram
b. Karyograph
c. Karyotype
d. Photocytogenetic plot
