2011年3月11日の東日本大震災に伴い,福島第一原子力発電所の事故が発生した。この事故後から東京都内(世田谷区深沢)で大気浮遊塵,農畜水産物,浄水の放射能濃度及びγ線の空間線量率のモニタリングを行ってきた。5月31日までの測定結果を基に132Te,131I,132I,134Cs,137Csの5核種による内部被ばく線量及び空間線量率による外部被ばく線量を試算した。その結果,測定開始から1年間の積算線量は425.1μSvとなり,ICRPの定める一般公衆の年間被ばく限度(1mSv)を超えないものと推定された。

Part I and Part II of this paper appear in Nos. 317 and 319 of the Bijutsu Kenkyu. In the present part the subjects of Scrolls 6, 7 and 8 are described. Scroll 6 is the scene of Suppression of Demons. At the center of the picture is the troop of the Demon King attacking Śākyamuni. The heads of the arrows shot toward Śākyamuni are trasformed into lotus flowers. The three daughters of the Demon King are depicted at the lower left of the picture ; the daughters transformed into old women by Śākyamuni are at the middle of the bottom; and Pṛthivi who has appeared to prove the righteousness of Śākyamuni is at the lower right. The depiction of Pșthivī whose upper half of the body is emerging from the earth like this is rare. Furthermore, the figure of Śākyamuni meditating for seven days after the demon-suppression is added at the right hand side of the picture in a small size. Scroll 7 is the scene of King Bimbisāra's Conversion to Śākyamuni's Teaching after hearing his sermon. In the upper part of the picture is depicted the audience in front of Śākyamuni, including the king and his ministers, and elephant carriages and attendants waiting the return of the king are in the lower half. Behind Śākyamuni is Gṛdhrakūta Mountain with its eagle-headed peak, suggesting that Śākyamuni is preaching. Also, the wheels of law painted between Śākyamuni and the kings symbolize his preaching. Scroll 8 is a visualization of three stories concerning the Nirvāṇa. The entire left half of the picture plane is devoted to a minute depiction of the Nirvāṇa scene which embodies details like Mahāmāyā with her attendants and the old women near Sākyamuni's feet. The lower right of the picture plane is the cremation of Śākyamuni. Here, as MahāKāśyapa, who could not come to see Śākyamuni upon his deathbed, worships the coffin placed on firewood, feet of Śākyamuni appear from the coffin. The upper right is the scene of distribution of Śākyamuni's relics in which a brāhmaṇa Droṇa divides the relics.

熱ルミネッセンス(TL)法による照射食品の検知は、欧州でハーブやスパイス、バレイショなどを対象に試験室間共同試験が実施され、分析法としての妥当性が確認されている。TL法は1996年に欧州規格EN1788となり、2001年に改訂され現在に至っている。本研究では、海外旅行者がトルコの空港で購入したスパイス(12種類)を試料として、TL測定を行った。TL比の算出にあたっては、当所で使用している70〜400℃の積算温度範囲の他に、EN1788が推奨するTLD-100素子で設定した積算温度範囲、およびDolomiteから試作した素子で設定した積算温度範囲も採用した。それぞれの積算温度範囲から算出した積算発光量のTL比に与える影響を調べた。TLD-100とSaffronについては、2つの研究機関で発光ピーク温度やTL比を測定し比較した。
