skos:definition "A set of conditions that warrant a similar immediate 'emergency response'.<br/>
This is the term used for communicating to the 'response organizations' and the <br/>public the level of response needed. The 'events' that belong to a given <br/>'emergency class' are defined by criteria specific to the installation, 'source' or <br/>'practice', which, if exceeded, indicate classification at the prescribed level. For <br/>each 'emergency class', the initial actions of the 'response organizations' are <br/>predefined.<br/>The IAEA defines three 'emergency classes', namely (in order of increasing <br/>severity) 'alert', 'site area emergency' and 'general emergency'. In alphabetical <br/>order:<br/>
<i><b>alert.</b></i> An 'event' involving an unknown or significant decrease in the level <br/>of 'protection' for the public or 'on-site' personnel.<br/>
When an 'alert' is declared, the state of readiness of the 'on-site' and <i>off-site<br/>response organizations</i> is increased and additional 'assessments' are made.<br/>
<i><b>general emergency.</b></i> An 'event' resulting in an actual release, or substantial <br/>probability of a release, requiring implementation of <i>urgent protective <br/>actions</i> 'off-site'.<br/>
This includes: (1) actual or projected damage to the reactor core or large <br/>amounts of 'spent fuel'; or (2) releases 'off-site' resulting in 'doses' exceeding <br/>'intervention levels' for 'urgent' 'protective actions' within hours.<br/>When a 'general emergency' is declared, 'urgent protective actions' are <br/>recommended immediately for the public near the 'facility'.<br/>
<i><b>site area emergency.</b></i> An 'event' resulting in a major decrease in the level of <br/>'protection' for the public or 'on-site' personnel.<br/>
This includes: (1) a major decrease in the level of 'protection' provided to the <br/>reactor core or large amounts of 'spent fuel'; or (2) conditions where any <br/>additional 'failures' could result in damage to the reactor core or 'spent fuel'; or <br/>(3) high 'doses' 'on-site'.<br/>When a 'site area emergency' is declared, preparations should be made to take <br/>'protective actions' 'off-site' and to control the 'doses' to 'on-site' personnel.<br/>" (en)
