Deterministic Effect Flashcards
(62 cards)
radiation response occurs within days to months
deterministic effect
radiation response increases in sevierty
deterministic effect
is the most devastating human response to radiation exposure
death
always result in partial-body exposure
diagnostic x-ray beam
sequence that follow high-level radiation exposure leading to death within days or weeks
acute radiation syndrome
this immediate response of radiation sickness
prodromal period
is the time after exposure during which is no sign of radiation exposure
latent radiation
after the period of initial radiation sickness well-being occurs
apparent
approximately dose: > 1 Gyt
prodromal period
approximately dose: 1-100 Gyt
latent period
clinical sign and symptoms: nausea, vomiting, diarrhea
prodromal period
there is NONE clinical sign and syndrome
latent period
is characterized by possible vomiting mild diarrhea, malaise, lethargy, and fever
manifest illness
at very high radiation dose, the ___ disappears altogether
latent period
at very low radiation dose, there may be no ___ at all
prodromal period
as the whole-body radiation dose increases, the average time between exposure and death decreases
mean survival time
what are the three syndromes
central nervous syndrome
gastrointestinal syndrome
hematologic syndrem6
reduction or red, white blood cells, and platelets
hematologic syndrome
hematologic syndrome and CNS syndrome of mean survival time
dose dependent
G1 syndrome of mean survival time
remain constant at 4 days
severe damage to the cells lining the intestine
gastrointestinal period
the ultimate cause of death in CNS syndrome is elevated fluid content of the brain
central nervous syndrome
is the dose of radiation to the whole body
LD 50/60
no one is expected to die
1 Gyt (100 rad)
