Questions and Answers

What characterizes deterministic effects in tissue due to radiation exposure?

  • They result from low doses of radiation over time.
  • They occur only after a long duration of exposure.
  • They do not affect living tissues.
  • They are short-term adverse reactions from high doses. (correct)

    • How do deterministic effects differ from stochastic effects in radiation exposure?

  • Deterministic effects show a threshold dose for adverse effects. (correct)
  • Stochastic effects require significantly higher doses.
  • Stochastic effects manifest shortly after exposure.
  • Deterministic effects are random and unpredictable.

    • What is a possible consequence of deterministic effects in tissues?

  • Immediate tissue damage or necrosis. (correct)
  • Chronic fatigue syndrome.
  • Gradual development of cancer.
  • Development of genetic mutations.

    Study Notes

    Deterministic Effects

    • Deterministic effects are short-term, adverse tissue reactions caused by high radiation doses.
    • These effects occur when radiation damage is significant enough to impair tissue or organ function.
    • They arise from cell death, which can be local, affecting only a specific part of the body, or systemic, impacting the entire body.
    • Local tissue damage can manifest months or even years after exposure depending on the tissue type and dose intensity.
    • A sequence of exposures can also trigger these effects.
