大放研・先端研50周年記念集会 (The Jubilee Memorial Meeting of RCOP–RIAST)

　昨11月27日（日）午後、ホテルグランビア大阪において「大放研・先端研50周年記念集会」が開催され、参加した。「大放研」は私の最初の職場（大阪府立放射線中央研究所）の、「先端研」はそれが大阪府立大学に統合され変身したあと（先端科学研究所）の、いずれも略称で、私が生涯を通じて働いた場所はこの集会名に集約されている。先端研も私の退職数年後から機構改革を受けて、名称が後述のように変ってしまった。したがって、いまや大放研の名だけでなく、先端研の名も正確には「旧」の文字を被せられなければならない。集会は、大放研の開所式から数えて今年が50年目ということで企画された。筑波、東京、金沢など遠方からの参加者もあり、事務系の人たちも含めて94名が出席し、盛大な集まりだった。

In the afternoon of November 27 (Sunday), I attended the Jubilee Memorial Meeting of RCOP–RIAST held at Hotel Granvia Osaka. "RCOP" is the acronym of my first place of work (the Radiation Center of Osaka Prefecture); and "RIAST," that of the same institution after being integrated into Osaka Prefecture University (Research Institute of Advanced Science and Technology). So, the names of my places of employment during all my life are contained in the title of this meeting. A few years after my retirement from RIAST, the name of the institution was changed again as given below, as the result of the reorganization of the university. Therefore, the name RIAST, as well as the name RCOP, should properly be preceded by the word "former." The meeting was held because it is now the 50th year from the year in which the opening ceremony of the RCOP was held. The total number of participants was 94, including many persons who worked in the administration department, so that it was a pretty large gathering. Some participants came from distant places such as Tsukuba, Tokyo and Kanazawa.

The top photo shows Mr. Morikazu Itakura, the first Head, Division of General Affairs, talking about the reminiscence of the early days of the RCOP. The bottom photo shows Professor Shuichi Okuda (Director, Radiation Research Center, Local Collaboration Research Establishment, Osaka Prefecture University*) delivering closing remarks. (The meeting was of buffet-style, and at the time of Okuda's remarks, many of the attendees were either sitting on chairs against the wall because of fatigue coming from their old age or gathering around the tables for dessert and coffee at the back of the venue. Thus, I was unable to make this a photo to show how a large number of attendees there were.)

* "Radiation . . . University" is the current name of the institution that keeps the equipment of the RCOP.
