Autor: Ken Abe, Hisao Kobayashi, Masahiro Takebe, Hoshio Eguchi, Masahiro Etoh, Hiromi Shibata, Masanori Satoh

Publikováno v: Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms. :938-943

A photo-stimulated luminescent (PSL) material, BaFBr 0:85 I 0:15 :Eu 2⁄ , was irradiated by 1 and 2 MeV He ⁄ ions. Thedeterioration of PSL signals caused by heavy irradiation was found quite stable for a long time. In situ measurements ofscintill

Radiation effects of helium ions, neutrons, and gamma-rays on photo-stimulated luminescence

Autor: Ken Abe, Hiromi Shibata, Hoshio Eguchi, Hisao Kobayashi, Masahiro Etoh, Masahiro Takebe, Masanori Sato

Publikováno v: Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms. 135:229-233

A photo-stimulated luminescent (PSL) material, BaFBr 0.85 I 0.15 : Eu 2+ , was irradiated by 1 and 2 MeV He + ions. The radiation effects were compared with that of fission neutrons, 137 Cs and 60 Co gamma-rays. Deterioration of PSL signals was measu

Rapid Decrease in DNA Content Induced by Gamma Irradiation in Cultured Cells of Tobacco

Autor: Mitsuhiro Hatanaka, Akira Kanazawa, Atsushi Hirai, Hoshio Eguchi, Nobuhiro Tsutsumi

Publikováno v: RADIOISOTOPES. 47:399-404

The effect of gamma irradiation on the growth rate, on the amount of soluble protein and on the amount of DNA in tobacco calli was analyzed. A significant decrease in the amount of DNA was detected in the calli of every growth stage after incubation

Gamma irradiation system with variable effective half-life function and its characteristics on spatial dose distribution

Autor: Ken-ochi Ijiri, Akihiro Shima, Hoshio Eguchi, Toshiso Kosako, Tsugio Shiroya, Shigemitu Tano

Publikováno v: RADIOISOTOPES. 37:568-571

The gamma irradiation system with variable effective half-life function has been developed, which provides the low dose rate gamma irradiation field by two 137Cs sources (3.7×1010 Bq and 7.4×1011 Bq) . This apparatus was designed to give an exposur

Thermoluminescence studies on plant seeds of different radiosensitivity

Autor: Y. Koizumi, Hoshio Eguchi, Hikoyuki Yamaguchi

Publikováno v: Journal of radiation research. 16(3)

The thermoluminescence was found when the pulverized powders from the whole seeds of six plant species or the hypocotyls from the seeds of five soybean varieties were irradiated at a liquid nitrogen temperature with gamma-rays. The spectra of lumines
