LRA 215: Legal Research and Analytical Methods Exam
Linear Energy Transfer (LET) - answers✔✔measure of the rate at which energy is transferred
from ionizing radiation to soft tissue. expressed in kiloelectron volts per micrometer of soft
tissue
Oxygen Enhancement Ratio (OER) - answers✔✔ratio of the dose necessary to produce a given
effect under anoxic conditions to the dose necessary to produce the same effect under aerobic
conditions
threshold dose - answers✔✔dose below which a person has a negligible chance of sustaining
specific biologic damage, or dose at which response to increasing x-ray intensity first occurs
interphase death - answers✔✔occurs when the cell dies before replicating
radiation weighting factor - answers✔✔factor used for radiation protection that accounts for
differences in biologic effectiveness between different radiations. formerly called quality factor
tribondeau - answers✔✔one of two french scientists, who in 1906, had a theory that became a
law, stating that metabolic and maturation state of tissues vary for being affected with
radiosensitivity
What is the formula for relative biological effectiveness - answers✔✔RBE=Dose of standard
radiation necessary to produce a given effect/ dose of test radiation necessary to produce the
same effect
, how does age affect the radiosensitivity of tissue? - answers✔✔in utero, at birth and during
childhood, our structures are still being formed which makes us more sensitive to
radiosensitivity. when you reach adulthood you are less prone to radiosensitivity. however it is
always important to make sure you're reproductive organs are covered when necessary
a dose of 10 Gy given to a patiet in 5 doses of 2 Gy per day is a _____ dose -
answers✔✔fractionated
Humans are most radiosensitive during ____ - answers✔✔fetal stages
Which dose-response relationship can follow a sigmoid curve? - answers✔✔Nonlinear-
nonthreshold
Tissue is ___ radiosensitive under high oxygen conditions and ___ radiosensitive under hypoxic
conditions - answers✔✔more, less
if a response to radiation is expected, no matter how small the dose, then that dose-response is
___ - answers✔✔linear
fraction and protraction are used for radiation therapy because they allow the patient to ___ -
answers✔✔repair damaged tissues, recover between doses, have higher total doses
the law of ___ states that the radiosensitivity of living tissue is a function of the metabolism and
maturation of that tissue - answers✔✔bergonie and tribondeau
the rbe of diagnostic x-rays is equal to __ - answers✔✔1
