Optimisation and accidents Abstract - Although this draft cites, gthe 2005 Recommendations entails consideration of the avoidance of accidentsh, no more detailed description is given about this topic in the present draft. If optimisation is going to include the avoidance of accidents, I would like to hear how optimisation is to be realised, what points should be checked and what accidents have occurred due to the neglect of optimisation. General - The term, gstakeholderh, Expressing my opinion now may be too late, because the term, gstakeholderh, has been used since the publication of ICRP Publication 82. In spite of its definition of the term, that is, gthose parties who have interests in and concern about a situationh, the original meaning of the word is ga person entrusted with the stakes of bettorsh (Merriam-Webster Online Dictionary). The translation of the term into Japanese is difficult, so I wish the term be changed. I wonder if those parties who have interests in and concern about a situation would be pleased when they are called person related with a bet.
