late effects of radiation Flashcards
what are late effects of radiation exposure
radiation damage at cellular level’s measurable somatic and genetic damage in the organism as a whole
lat effects can result from: (3)
- prev whole or partial acute exposure
- prev high radiation doses
- long term low level doses
late effects come from cells that __
are damaged, but continue to live
stochastic and genetic effects tnd to follow what curve
a linear non-threshold
what are non stochastic late effects
late effects that can be directly related to dose recieved
what er 4 non stochastic late effects
cataracts
serility
fibrosis
atrophy
what are stochastic effects
later responses that have no threshold
what are the 2 stochastic late effects
cancer
