Seasonal Variations in Radon and Thoron Exhalation Rates from Solid Concrete Interior Walls Observed Using In Situ Measurements
Autor: Akihiro Sakoda, Yuu Ishimori, Md. Mahamudul Hasan, Qianhao Jin, Takeshi Iimoto
Publikováno v: Atmosphere, Vol 15, Iss 6, p 701 (2024)
Building materials, such as brick and concrete, are known indoor radon (222Rn) and thoron (220Rn) sources. Most radon and thoron exhalation studies are based on the laboratory testing of pieces and blocks of such materials. To discuss if laboratory f

Dosimetry of radon progeny deposited on skin in air and thermal water
Autor: Takahiro Kataoka, Hiroshi Tanaka, Yuu Ishimori, Norie Kanzaki, Fumihiro Mitsunobu, Kiyonori Yamaoka, Akihiro Sakoda
Publikováno v: Journal of Radiation Research
It is held that the skin dose from radon progeny is not negligibly small and that introducing cancer is a possible consequence under normal circumstances as there are a number of uncertainties in terms of related parameters such as activity concentra

Environmental monitoring of trace elements and evaluation of environmental impacts to organisms near a former uranium mining site in Nigyo-toge, Japan
Autor: Sawako, Horai, Shoichi, Murakami, Akihiro, Sakoda, Rumiko, Nakashita, Tatsuya, Kunisue, Yuu, Ishimori
Publikováno v: Environmental Monitoring and Assessment. 194
This study was conducted to find out characteristics of trace element levels and those impacts to organisms at a former uranium (U) mining site. Concentrations of trace elements (Li, Mg, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Rb, Sr, Mo, Cd, Cs, Ba,

METHODOLOGY FOR SIMPLE SPOT MEASUREMENT OF EQUILIBRIUM EQUIVALENT RADON CONCENTRATION
Autor: Hiroshi Tanaka, Norie Kanzaki, Akihiro Sakoda, Yuu Ishimori
Publikováno v: Radiation Protection Dosimetry. 191:383-390
Estimation of the effective inhalation dose of short half-life radon progeny requires the quantification of radon equilibrium equivalent activity concentrations (EEC, Ceq). The aim of the present study is to develop new methodology that focuses on sp

Concentration ratios of 238U and 226Ra for insects and amphibians living in the vicinity of the closed uranium mine at Ningyo-toge, Japan
Autor: Shoichi Murakami, Yuu Ishimori, Akihiro Sakoda, Sawako Horai
Publikováno v: Journal of Radiation Research
There is still a scarcity of data on the transfer of naturally occurring radionuclides to wildlife in various ecosystems. In the present study, concentration ratios (CRwo-media) of 238U and 226Ra were obtained for grasshoppers, frogs and newts in ter

Production and detection of fission-induced neutrons following fast neutron direct interrogation to various dry materials containing 235U
Autor: Akihiro Sakoda, Akira Ohzu, Shinichi Nakashima, Yosuke Toh, Masao Komeda, Yuu Ishimori, Yoshiaki Nakatsuka
Publikováno v: Journal of Nuclear Science and Technology. 55:605-613
For better nuclear material accountancy, we had developed a non-destructive assay system dedicated to uranium waste drums (JAWAS-N: JAEA Waste Assay System at Ningyo-toge). The system is based on a fast neutron direct interrogation (FNDI) method. To

Protective effects of hot spring water drinking and radon inhalation on ethanol-induced gastric mucosal injury in mice
Autor: Hiroshi Tanaka, Takahiro Kataoka, Fumihiro Mitsunobu, Akihiro Sakoda, Reo Etani, Yuu Ishimori, Norie Kanzaki, Kiyonori Yamaoka, Takehito Taguchi
Publikováno v: Journal of Radiation Research
Radon therapy using radon (222Rn) gas is classified into two types of treatment: inhalation of radon gas and drinking water containing radon. Although short- or long-term intake of spa water is effective in increasing gastric mucosal blood flow, and

Measurements of radon activity concentration in mouse tissues and organs
Autor: Hiroshi Tanaka, Kiyonori Yamaoka, Fumihiro Mitsunobu, Akihiro Sakoda, Yuu Ishimori, Takahiro Kataoka
Publikováno v: Radiation and Environmental Biophysics. 56:161-165
The purpose of this study is to investigate the biokinetics of inhaled radon, radon activity concentrations in mouse tissues and organs were determined after mice had been exposed to about 1 MBq/m3 of radon in air. Radon activity concentrations in mo
