Exposure analysis is the science that describes how an individual or population comes in contact with a contaminant, including quantification of the amount of contact across space and time. 'Exposure assessment' and 'exposure analysis' are often used as synonyms in many practical contexts. Risk is a function of exposure and hazard.
Estimating or calculating the dietary exposure to a given chemical or contaminant allows a comparison to a relevant health standard such as the acceptable daily intake(ADI), the acute reference dose (ARfD) or a reference dose (RfD), or a level known to cause adverse effects in animal or human health studies.

The United States Environmental Protection Agency defines NOAEL as 'an exposure level at which there are no statistically or biologically significant increases in the frequency or severity of adverse effects between the exposed population and its appropriate control; some effects may be produced at this level, but they are not considered as adverse, or as precursors to adverse effects.

Worst-case analysis is the analysis of a device (or system) that assures that the device meets its performance specifications. These are typically accounting for tolerances that are due to initial component tolerance, temperature tolerance, age tolerance and environmental exposures (such as radiation for a space device).
Georgia's season is over after a 23-10 loss to Notre Dame in the Sugar Bowl, but the single moment that really ended it came with a little less than eight minutes remaining in the fourth quarter. ...
