Map Viewing Service (WMS) of the dataset: Superfacial entity at the origin of the risk of PPRi Essonne — Loiret

The origin of the risk characterises the real-world entity which, through its presence, represents a potential risk. This origin may be characterised by a name and, in some cases, a geographical object locating the actual entity causing the risk. The location of the entity and the knowledge of the hazardous phenomenon are used to define the risk pools, the risk-exposed areas that underpin the RPP.For NPPs, this entity may, for example, correspond to a river, a geologically unstable area.风险源指的是一类现实存在的实体，其存在本身即构成潜在风险。该风险源可通过名称进行表征，在部分场景下还可借助用于定位该风险致因实体的地理对象来实现标识。实体的空间位置与对危险现象的认知，被用于界定风险池——即支撑RPP的风险暴露区域。以核电厂（NPPs）为例，此类实体可对应为河流、地质不稳定区域。
