Contingency

With respect to Radiation Protection, contingency means preparing for, and taking action, in the event of an unplanned release of Radioactive material or other unplanned Radiation incident which could lead to radiation exposure to the individual, the population or environment. Contingency may be determined by simple risk assessment or by a more comprehensive Probabilistic Safety Assessment (PSA) as part of a Safety Case. Usually contingency arrangements deal with Reasonably Foreseeable (credible) events, although for some industries (e.g. nuclear), the contingency plans have to be extendable.

Physics is really nothing more than a search for ultimate simplicity, but so far all we have is a kind of elegant messiness
