STOCHASTIC EFFECTS

Physics

STOCHASTIC EFFECTS

1. Arise by chance.

2. No threshold.

3. Probability of effect is related to dose.

4. Risk increases linearly with dose.

5. Severity does not increase with dose as this effect is binary (e.g. the patient either gets cancer or does not).

6. Effective dose more accurately describes this as it takes into account the whole body, tissue & radiation weighting factors.
