What type of dose-response Deterministic (nonstochastic)
relationship is characterized by an
early response to a high-dose
exposure?
What type of dose-response Stochastic (probabilistic)
relationship is characterized by a late
response to low-dose exposures?
What is described as a measure of LET (linear energy transfer)
the rate at which energy is transferred
from ionizing radiation to soft tissue?
What are two examples of radiation- Genetic effects, radiation-induced cancer, leukemia
induced conditions that follow a
linear nonthreshold dose-response
relationship?
Skin effects that result from Nonlinear (sigmoid), threshold dose response
fluoroscopic exposure follow what
type of dose-response relationship?
, What type of effects are described Nonstochastic (deterministic) effects
as: "those biologic somatic effects of
ionizing radiation that exhibit
threshold dose below which the
effect does not normally occur and
above which the severity of the
biologic damage increases?
What is the cellular component DNA
having the greatest radiobiological
signigicance?
What effect does the presence of Oxygen increases radiosensitivity
oxygen have on radiosensitivity?
Which of the following ionizing Alpha
radiations has the highest LET?
ALPHA
BETA
GAMMA
What is the term used to describe the Acute radiation syndrome
human sequence of events following
high-level radiation exposure, and
leading to death in a short time?
List three major types of acute Hematological, gastrointestinal, and CNS (central
radiation syndrome. nervous system)
Which of the three types of acute Hematological
radiation syndrome requires the least
amount of ionizing radiation dose to
occur?
