Abstract: Disclosed is a compound suitable for use as a fluorescent probe for the detection of uranium. The compound enables the qualitative and quantitative analysis of uranium present in waste samples using less expensive apparatuses. The compound of the present invention has the structure shown by the following formula.

Abstract: A calculation apparatus comprising: an acquiring unit to acquire an azimuth and an ellipticity angle of a polarization plane of a laser beam passing through a plasma; and a calculation unit to calculate at least one of a magnetic field profile, an electron density profile and an electron temperature profile in the plasma on the basis of the azimuth and the ellipticity angle.

Abstract: To provide a method of producing radioactive molybdenum solution suitable for extracting 99mTc to be used as radioactive diagnostic drug by way of establishing a production process for high-density MoO3 pellets with a lower amount of insoluble content when dissolving the pellets. The method has the steps of: preparing MoO3 powder, fabricating a MoO3 pellet by filling said MoO3 powder in a heated die and sintering in an air, oxidizing said MoO3 pellet, producing neutron-irradiated MoO3 pellets by irradiating a neutron on said oxidized MoO3 pellet, and obtaining radioactive molybdenum solution by dissolving said neutron-irradiated MoO3 pellet.

Abstract: A mixture of a raw material poorly water-soluble polysaccharide or derivative thereof in an ionic liquid-containing solvent is exposed to radiation. Accordingly, a polysaccharide gel producing process is provided that can produce a gel without performing a special pretreatment for the raw material.
