Over Exposure

With respect to Radiation Protection, an overexposure means a person who has received an unexpected (non-routine) level of Ionising Radiation exposure above some permitted level (Dose Limits). The overexposure may result in a breach of regulations, but in severe cases adverse health effects or even death (see Deterministic Effects).

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