Abstract: An apparatus for filtering airborne radioactive iodine is provided. The apparatus includes a housing defining an interior space and comprising an inlet for receiving air and an outlet for discharging the air; and a composition placed in the interior space for trapping airborne radioactive iodine between the inlet and the outlet. The composition comprises one or more salts selected from the group consisting of an alkali metal chloride and an alkaline earth metal chloride. A method of filtering airborne radioactive iodine is further provided. The method includes providing the foregoing apparatus at a nuclear facility and blowing air to flow from the inlet to the outlet and contact the composition placed in the interior space, whereby airborne radioactive iodine is trapped in the interior space.

Abstract: A method of preparing a silicon thin film, silicon thin film prepared using the method, and an electronic device including the silicon thin film are provided. The method includes applying an oxidized silicon element solution to a substrate and sintering the silicon oxide film to prepare a compact silicon oxide thin film, electrochemically reducing the silicon oxide thin film to form a porous silicon film, and re-sintering the porous silicon film. Therefore, the silicon thin film used in semiconductors, solar cells, secondary batteries and the like can be easily prepared at a low cost with a smaller number of processes than the conventional methods, and thus price competitiveness of products can be enhanced.
