The Abstract says, “this publication provides a framework for the protection of people and the environment in the case of large nuclear accidents, drawing on the experience of Chernobyl and Fukushima.”(line 8-10)
“Foreword” should be put ahead of the “Introduction” that describes what the ICRP have learned from the Chernobyl and Fukushima. These incidents have taught us that nuclear reactors in action may cause severe accidents by human errors or/and by natural disasters. As far as we continue activate the reactors in the world, it is perhaps impossible to avoid next one like Fukushima in foreseeable future. Therefore, the best way to avoid occurrence of next severe accidents like Fukushima is to stop activation of all nuclear reactors in the world. Even if it is improbable that the governments and other institutions concerned do not agree to stop using atomic reactors, we should request and recommend that they minimize activation of the reactors especially older and relatively riskier ones.
It means that ICRP, first of all, are strongly determined to prevent re-occurrence of these disastrous nuclear accidents. Of course this report is not directly discussing regulation of the reactors, it must say something like “no more Fukushima” at the top of it.
Without foreword like this, the readers of the report may forget the most important lesson.
