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.

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.
