Journal ArticleDOI
Seasonal characteristics of organic and inorganic species and their size distributions in atmospheric aerosols over the northwest pacific ocean
TL;DR: In this article, simultaneous measurements of chemical compounds in atmospheric aerosols, cloud condensation nuclei (CCN) and associated species were conducted from December 1994 to January 1997 at Hahajima, the Ogasawara Islands, in the northwest Pacific Ocean, being located on the lee of the large east Asian polluted region.
Journal ArticleDOI
An electrostatic integrating 222Rn monitor with cellulose nitrate film for environmental monitoring.
Takao Iida,Yukimasa Ikebe,Takatoshi Hattori,Hirokuni Yamanishi,Siro Abe,Kiyoshi Ochifuji,Shintaro Yokoyama +6 more
TL;DR: This paper describes a new type of electrostatic integrating 222Rn monitor designed for the environmental222Rn monitoring, and the window area of the monitor was selected to make the exchange rate optimal.
Journal ArticleDOI
Automobile exhaust as a source of 13C- and D-enriched atmospheric methane in urban areas
Fumiko Nakagawa,Urumu Tsunogai,Daisuke D. Komatsu,Keita Yamada,Naohiro Yoshida,Jun Moriizumi,Koichiro Nagamine,Takao Iida,Yukimasa Ikebe +8 more
TL;DR: The stable carbon and hydrogen isotopic compositions (δ13C and δD, respectively) of methane (CH4) in automobile exhaust were determined in order to quantify by mass balance the contribution from this source to atmospheric CH4 in an urban area of Nagoya, Japan as discussed by the authors.
Journal ArticleDOI
Estimation of areal flux of atmospheric methane in an urban area of Nagoya, Japan, inferred from atmospheric radon-222 data
TL;DR: In this paper, the authors have adopted atmospheric radon-222 (222Rn) as a natural tracer to clarify the emission of methane (CH4) from area sources.
Journal ArticleDOI
An alpha-particle imaging system for detecting plutonium contamination
Takao Iida,Seiichi Yamamoto,Yukimasa Ikebe,Akio Seki,Kei Nakata,Minoru Ebana,Masashi Kanamori,Mamoru Yoshida +7 more
TL;DR: In this article, a new type of alpha-particle imaging system was constructed to reduce the time required for detecting plutonium contamination, which required about one-seventh of the exposure time required by ZnS(Ag) autoradiography in order to distinguish between radon and thoron daughter products.
