skos:definition "<i><b>acute exposure.</b></i> 'Exposure' received within a short period of time.<br/>
Normally used to refer to 'exposure' of sufficiently short duration that the <br/>resulting 'doses' can be treated as instantaneous (e.g. less than an hour).<br/>Usually contrasted with 'chronic exposure' and 'transitory exposure'.<br/>
<i><b>chronic exposure.</b></i> 'Exposure' persisting in time. (From Ref. [1].)<br/>
<b>!</b> The adjective ‘chronic’ relates only to the duration of 'exposure', and does not <br/>
imply anything about the magnitude of the 'doses' involved.<br/>Normally used to refer to 'exposures' persisting for many years as a result of <br/>long lived radionuclides in the environment. 'Exposure' that is too protracted <br/>to be described as 'acute exposure', but does not persist for many years, is <br/>sometimes described as <i><b>transitory exposure</b></i>.<br/>
The International Commission on Radiological Protection uses the term <br/><i><b>prolonged exposure</b></i> to describe the same concept as 'chronic exposure'. Both <br/>terms are contrasted with 'acute exposure' (and 'transitory exposure'; see above).<br/>
<i><b>chronic potential exposure.</b></i> 'Potential exposure', the probability of <br/>occurrence of which persists in time.<br/>
In a 'chronic potential exposure' situation, the 'exposure', if it occurs, may be <br/>'acute exposure' or 'chronic exposure'; it is the potential for the 'exposure' to occur <br/>that persists in time.<br/>This describes a situation in which, for example, long lived radionuclides are <br/>present in a place such that people would not normally be exposed to the <br/>'radiation', but where future human actions could result in 'exposure'.<br/>The term ‘potential 'chronic exposure'’ would describe a situation (as yet only <br/>hypothetical) of 'potential exposure' in which the 'exposure', if it occurred, would <br/>be 'chronic exposure'. To date, however, no particular need for this term has <br/>been identified.<br/>
<i><b>normal exposure.</b></i> 'Exposure' that is expected to occur under the normal <br/>'operating conditions' of a 'facility 'or' activity', including possible minor <br/>mishaps that can be kept under 'control', i.e. during 'normal operation' and <br/>'anticipated operational occurrences'.<br/>
<i><b>potential exposure.</b></i> 'Exposure' that is not expected to occur with certainty <br/>but that may result from an 'accident' at a 'source' or owing to an 'event' or <br/>sequence of 'events' of a probabilistic nature, including equipment <i>failures<br/></i>and operating errors. (From Ref. [1].)<br/>
Such 'events' could also include 'accidents' or future 'events' influencing the <br/>integrity of a 'repository'.<br/>
<i><b>prolonged exposure.</b></i> See 'exposure situations: chronic exposure'.<br/>
<i><b>transitory exposure.</b></i> See 'exposure situations: chronic exposure'.<br/>" (en)
