A three-dimensional Eulerian atmospheric long-range transport model of radon-222 (^222Rn) and lead-210 (^210Pb) coupled with meteorological model MM5 was developed. The model calculates advection,...
Continuous Atmospheric Radon-222 Concentration Observation in East Asia (2008)
Moriizumi, Jun, Ohkuraa, Takehisa, Hirao, Shigekazu, Nono, Yuki, Yamazawa, Hiromi, Kim, Yoon-Shin, ...
Continuous observation of atmospheric radon-222 (^222Rn) concentration has been operated for years in China, Korea and Japan, including remote islands isolated in the ocean. The sites were allocated...
Estimation of global radon exhalation rate distribution (2008)
Goto, Masayoshi, Moriizumi, Jun, Yamazawa, Hiromi, Lida, Takao, Zhuo, Weihai
A radon exhalation rate distribution model was developed, which considers dependency on soil water saturation, soil temperature and soil texture. The global averages of the radon exhalation rates...

The indoor radioactive aerosols of radon decay products are considered as a main radioactive contaminant in human environment. In this study, the particle size distribution was measured with low...
Evaluation of aerosol sizing characteristic of an impactor using imaging plate technique (2007)
Rahman, Naureen Mahbub, Iida, Takao, Saito, Fumihiro, Koarashi, Jun, Yamasaki, Keizou, Yamazawa, Hiromi, ...
The activity-size distribution of radon decay products are normally determined using two approaches: direct and indirect. The present study utilises the direct approach to evaluate sizing information...
