-
list the three things radiation damage depends on
type of cell irradiated, dose received from the radiation and volume of tissue irradiated.
-
what can biological effects be split into
somatic effects, genetic effects
-
within somatic effects list some acute (early) and chronic (late) effects
- early- overdose/ accident cases like in screening or fluoroscopy,
- late- chromosomal damage, includes cancers, mentally ill children and fibrosis etc.
-
list some genetic effects
mutations in the ova/sperm, other disorders including leukaemia, birth defects and retardation.
-
what two things can radiation effects be split into
harmful tissue/deterministic effects, stochastic effects
-
what is the difference between deterministic effects and stochastic effects
- deterministic- have a threshold on effect it can occur, severity increases with dose,
- stochastic- happen by pure chance/random, no threshold for effect and frequency increase with dose.
-
give an example for deterministic and stochastic effect
- deterministic- male sterility and cataracts,
- stochastic- induction of cancers (reason why there is no such thing as safe dose of radiation too).
