Abstract: The present invention relates to a process for the decontamination of radioactively contaminated material comprising the steps of a) providing radioactively contaminated material in a decontamination bath (200), b) providing a reactor unit (107) comprising a first reactor chamber (102) connected to a second reactor chamber (103), c) electrolyzing water with a ph>7 in the first reactor chamber (102) and generating (H3O2)n, d) generating nanobubbles in the electrolyzed water of the second reactor chamber (103), e) optionally repeating steps c) and d), f) applying pressure to the water which contains nanobubbles, g) transferring the pressurized water which contains nanobubbles to a decontamination bath (200) containing an ?-ray generator and the radioactively contaminated materiel, h) charging the nanobubbles with the ?-particles emitted by the ?-ray generator, and i) bringing the charged nanobubbles in contact with the radioactively contaminated material in the decontamination bath (200).

Abstract: A device for improving combustion efficiency having an aluminum plate including a layer in one side thereof. The layer contains thorium oxide powder in a ratio of 1˜5 wt %. The device may be mounted in a section, such as a pipe, air cleaner, or fuel tank through which air, fuel or a mixture thereof passes. The air or fuel gets exposed to radiation of alpha-rays from thorium oxide power contained in the device resulting in air, fuel or a mixture thereof being activated. Since thorium oxide radiates primarily alpha-rays and almost no beta- or gamma-rays, the device promotes fuel combustion without any harm to human health. A method for producing the device is also disclosed.
