Bushong Chapter 33 and Chapter 34
correctly answered to pass graded A+
Stem Cells - correct answer ✔✔Cells that are most sensitive to radiation
Acute Radiation Syndrome - correct answer ✔✔Sequence of events that follow
high-level whole-body radiation exposure leading to death within days or weeks.
Deterministic Radiation response - correct answer ✔✔Responses that exhibit
increasing severity with increasing radiation dose.
Early effect of radiation exposure - correct answer ✔✔A radiation response in
humans within a few days to months, the dose must be substantial
Deterministic dose response relationship - correct answer ✔✔Nonlinear
Diagnostic x-ray beam - correct answer ✔✔always result in partial body exposure
which is less harmful than whole body exposure.
Syndromes that are acute radiation syndrome are: - correct answer
✔✔Hematologic death, gastrointestinal death, and central nervous system death
CNS death - correct answer ✔✔requires radiation doses of 50 GY or 5000 RAD
,Prodromal Period - correct answer ✔✔immediate response of radiation sickness
which would require a dose of 1 GY or 100 Rad
Symptoms of early radiation sickness - correct answer ✔✔nausea, vomiting,
diarrhea, and a reduction in white blood cells of the peripheral blood (leukopenia)
Radiation dose of 10 GY or 1000 rad - correct answer ✔✔symptoms are more
violent
Higher radiation doses - correct answer ✔✔the duration of the prodromal
syndrome becomes shorter until it is difficult to separate the prodromal period or
the period of manifest illness.
Latent Period - correct answer ✔✔time after radiation exposure during which
there is no sign of radiation sickness.
Hematologic syndrome or Bone Marrow Syndrome - correct answer
✔✔Characterized by a reduction in white blood cells, red blood cells, and
platelets.
Manifest Illness - correct answer ✔✔characterized by possible vomiting , mild
diarrhea, malaise, lethargy, and fever.
GI Death - correct answer ✔✔GI death occurs principally because of severe
damage to the cells lining the intestines.
, GI Radiation doses - correct answer ✔✔10 to 50 GY (1000-5000 RAD)
Prodromal period of GI - correct answer ✔✔vomiting and diarrhea occur withing
hours of exposure and persist for hours to as long as a day.
Manifest illness of GI - correct answer ✔✔begins with a second wave of nausea
and vomint followed by diarrhea. Loss of appetite, and becomes lethargic.
Latent period of GI last how long - correct answer ✔✔3 to 5 days
Intestinal Cells renewal time - correct answer ✔✔Need 3 to 5 days to renew
themselves
CNS Syndrome radiation dose - correct answer ✔✔Radiation dose in excess of
approximately 50 GY(5000 RAD)
CNS Symptoms - correct answer ✔✔severe nausea, vomiting begins within a few
minutes of exposure
Latent period of CNS - correct answer ✔✔12 hours
Manifest Illness of CNS - correct answer ✔✔symptoms of prodromal period
reappear but are more severe.
