International Nuclear and Radiological Event Scale INES

Member States use INES to provide a numerical rating that indicates the significance of nuclear or radiological events, Events are rated at seven levels, The scale is logarithmic – that is, the severity of an event is about ten times greater for each increase in level of the scale, Events are considered in terms of:
