Your quote does not address the point you suppose it to, PG. You need to work harder than that if you want to change everyone's perception that INES is, in fact, a logarithmic scale.
The generally accepted description of the INES scale from a physics blog:
IAEA: INES Scale for Nuclear Accidents and Nuclear Disasters
...
The INES Scale
The INES Scale is a seven point scale, with levels 1 to 3 being classified as incidents and levels 4 to 7 being classified as accidents. The INES is a logarithmic scale, which means that the severity of an event at one level is ten times greater than that of the level below it on the scale.
Events that do not have a safety significance are called deviations, and are classified as level 0.

No, a blog isn't the final word on this but it is an indicator that just your untrustworthy word is not enough.
I like this analysis of the impact designed into visual symbolism designed into the IAEA's messaging on nuclear accidents.

...There are two ways to draw a graphic scale such as this. This image emphasizes the relative rarity of a Level 7 Major Accident, compared with the more commonplace Level 1 Anomaly. This is the dont worry, these things almost never happen visualization.
However, according to the IAEA:
INES is a tool for promptly communicating to the public in consistent terms the safety significance of reported nuclear and radiological incidents and accidents.
In that case, it would more properly be drawn as an inverted pyramid, with the smallest area for the Anomaly at the bottom, and the largest for Major Accident at the top. While we normally associate things at the top as being more significant than things at the bottom, this image competes with that perception in two more ways. The shape of the pyramid creates a vanishing point sense of perspective that gives a feeling that Level 7 is something far, far away. Wide and stable Level 1 gives a feeling that it is something close and familiar, something solid, balanced and secure.
To communicate the concept of safety significance, the IAEA graphic relies entirely on cultural associations of the cool color green to communicate relative safety, and the hot color magenta to communicate relative danger. The colors certainly carry some meaning, but we usually perceive smaller areas to be less important than larger areas in most images. So this visualization presents the information in a way that does not fully communicate its impact.
Whats more, this visualization would not carry the full message even if the pyramid was inverted and the areas were reversed...
