Stochastic effects

Dr Henry Knipe and Dr Jeremy Jones et al.

Stochastic effects occur by chance and can be compared to deterministic effects which result in a direct effect.

Cancer induction as a result of exposure to radiation is thought by most to occur in a stochastic manner: there is no threshold point and risk increases in a linear-quadratic fashion with dose. This is known as the linear-quadratic no threshold theory (LNT). The LNT is not universally accepted with some proposing an adaptive dose–response relationship where low doses are protective and high doses are detrimental 4.

Although the risk increases with dose, the severity of the effects do not; the patient will either develop cancer or they will not.
