Formation of organically bound deuterium at each growing stage of rice

Uptake of tritium by food plants is an important pathway in transferring tritium to the human body. Plants take up tritium as the form of water and a part of tritiated water (HTO) is converted to organically bound tritium (OBT). The formation of OBT in plants depends on the growth stage when the contamination occurs. Potted rice plants were exposed to deuterated water vapor, as a substitute for HTO vapor, for 4 h at 5 different times during the grain ripening period to estimate the influence of the growth stage on the formation and retention of organically bound deuterium (OBD) in rice. The plants were grown outside before and after the exposure experiments and were exposed to deuterated water vapor in a laboratory in a small chamber equipped with controllers of temperature, humidity and light intensity.The mass of OBD in grain at harvest showed the highest value when the exposure was carried out in the early stage of the ripening period. When the exposure was carried out after 26 day from the heading, the increase of OBD in the grain was a little.

Development of dynamic compartment model for estimation of C-14 behavior in paddy field

Atarashi-Andoh, Mariko; Amano, Hikaru

Proceedings of International Symposium on Radioecology and Environmental Dosimetry, p.484 - 487, 2003/00

C-14 is one of the radionuclides released to the environment with routine operations of nuclear facilities. A dynamic compartment model was developed for estimation of C-14 behavior in paddy field. It calculates carbon transfer among air, rice, irrigation water and soil. The calculation was carried out using MOGRA: a generic analysis code of dynamic compartment model.

Periodic hole structure in a spin-chain ladder material Sr$$_{14}$$Cu$$_{24}$$O$$_{41}$$

Fukuda, Tatsuo; Mizuki, Junichiro; Matsuda, Masaaki

Physical Review B, 66(1), p.012104_1 - 012104_4, 2002/07

 Times Cited Count:16 Percentile:37.02(Materials Science, Multidisciplinary)

High-energy synchrotron X-ray diffraction measurements were carried out on a single crystal of Sr$$_{14}$$Cu$$_{24}$$O$$_{41}$$, and we found that the lattice distortion has not $$four$$ but $$five$$ times the periodicity of the chain structure along $$c$$(/$// chain axis) direction at low temperature. These satellite peaks decreased in intensity with increasing temperature. These observations were interpreted properly in terms of a hole ordering model involving the dimerized state of two Cu$^{2+}$$ ions and a Cu$$^{3+}$$ ion on a Zhang-Rice singlet site in the CuO$$_2$$ chains. These features were clearly observed by using high-energy X-rays ($$E_isimeq$$53.789 keV), while the superlattice peak intensity varied drastically with very little sample surface treatment in the case of low-energy X-ray experiments ($$E_isimeq$$15.498 keV).

Formation and retention of organically bound deuterium in rice in deuterium water release experiment

Atarashi-Andoh, Mariko; Amano, Hikaru; Kakiuchi, Hideki; Ichimasa, Michiko*; Ichimasa, Yusuke*

As a substitute of tritium, deuterium water (D2O) vapor release experiments were performed to estimate the difference of formation and subsequent retention of organically bound deuterium (OBD) in rice plants between daytime and nighttime exposure. Potted plants were exposed to deuterium water vapor in a greenhouse for 8 hours, under day and night conditions. Deuterium concentrations in free water and organic matter in rice leaves and ears were investigated until the harvest time. Data analysis was carried out using a model in which different generating processes of organic matter were considered. The calculated results agreed with the measured value.
