stochastic effects

effects produced at random without a threshold dose level, the probability of their occurrence being proportional to the dose and their severity being independent of it. In radiation safety, the main stochastic effects are carcinogenesis and genetic mutation.

By setting dose units below the thresholds, radiological protection aims to avoid deterministic and stochastic effects.
As the real world is not deterministic it is important to examine the inclusion of stochastic effects into deterministic models and this paper is a step towards doing this.
From the actual data collected, however, it appears that for such an outbreak, stochastic effects are less crucial near the beginning and end of the outbreak episode.
16) This is the population that we believe is at the highest risk for potential stochastic effects.
Stochastic effects are observed during exposure at higher doses of ionizing radiation than those encountered in a normal environment.
Stochastic effects can be recognized because founder effect and genetic drift in small populations produce a characteristic pattern of morph-frequency variation and morph loss (Heuch 1980; Barrett et al.
In either extreme, of course, it is well known that pricing and output levels are independent of structure; in such cases, a structural antitrust policy would have no impact on social welfare apart from possible deadweight losses or the stochastic effects analyzed here.
Systems Biology is now entering a mature phase in which the key issues are characterising uncertainty and stochastic effects in mathematical models of biological systems.
It is the stochastic effects that occur at any dose level that are of concern, as they are potentially carcinogenic and can cause gene mutations in subsequent generations.
These stochastic effects can occur as cancer or genetic alterations, and it is impossible to determine who could develop them as a result of radiation exposure.
Stochastic effects are random effects due to low-dose damage to single cells.
