Measurement and comparison of individual external doses of high-school students living in Japan, France, Poland and Belarus -- the "D-shuttle" project --

Twelve high schools in Japan (of which six are in Fukushima Prefecture), four in France, eight in Poland and two in Belarus cooperated in the measurement and comparison of individual external doses in 2014. In total 216 high-school students and teachers participated in the study. Each participant wore an electronic personal dosimeter "D-shuttle" for two weeks, and kept a journal of his/her whereabouts and activities. The distributions of annual external doses estimated for each region overlap with each other, demonstrating that the personal external individual doses in locations where residence is currently allowed in Fukushima Prefecture and in Belarus are well within the range of estimated annual doses due to the background radiation level of other regions/countries

3D MODELLING OF THE LUSATIAN BOROUGH IN BISKUPIN USING ARCHIVAL DATA

The paper presents the results of 3D modelling in the Lusatian Borough, Biskupin, using archival data. Pre-war photographs acquired from different heights, e.g., from a captive balloon (maximum height up to 150 m), from a blimp (at a height of 50–110 m) and from an aeroplane (at a height of 200 m, 300 m and up to 3 km). In order to generate 3D models, AgiSoft tools were applied, as they allow for restoring shapes using triangular meshes. Individual photographs were processed using Google SketchUp software and the "shape from shadow" method. The usefulness of these particular models in archaeological research work was also analysed
