Investigation of Spatial Distribution of Radiocesium in a Paddy Field as a Potential Sink
Surface soils, under various land uses, were contaminated by radionuclides that were released by the Fukushima Daiichi Nuclear Power Plant accident. Because paddy fields are one of the main land uses in Japan, we investigated the spatial distribution of radiocesium and the influence of irrigation water in a paddy field during cultivation. Soil core samples collected at a paddy field in Fukushima showed that plowing had disturbed the original depth distribution of radiocesium. The horizontal distribution of radiocesium did not show any evidence for significant influence of radiocesium from irrigation water, and its accumulation within the paddy field, since the original amount of radiocesium was much larger than was added into the paddy field by irrigation water. However, it is possible that rainfall significantly increases the loading of radiocesium.published_or_final_versio
GRBs Optical follow-up observation at Lulin observatory, Taiwan
The Lulin GRB program, using the Lulin One-meter Telescope (LOT) in Taiwan
started in July 2003. Its scientific aims are to discover optical counterparts
of XRFs and short and long GRBs, then to quickly observe them in multiple
bands. Thirteen follow-up observations were provided by LOT between July 2003
and Feb. 2005. One host galaxy was found at GRB 031203. Two optical afterglows
were detected for GRB 040924 and GRB 041006. In addition, the optical
observations of GRB 031203 and a discussion of the non-detection of the optical
afterglow of GRB 031203 are also reported in this article.Comment: 5 pages, 2 figure. Accepted for publication into "il nuovo cimento".
