Abstract: [PROBLEMS] To provide a scintillator responding to high counting rate sustaining high-speed and high detection efficiency of BaF2 and to provide a radiation detection device with high time resolution by using the scintillator. [MEANS FOR SOLVING PROBLEMS] A specified amount of rare earth element (Eu) is doped into BaF2 to reduce long decay lifetime component (600 to 620 nm), leaving fast decaying component (0.6 to 0.8 ns) of BaF2 luminescence unchanged. The present invention is a high counting rate scintillator for detecting radiation comprising BaF2 doped with rare earth elements (Eu), wherein the doping amount is in the range of 0.02 to 1.0 mol %.

Abstract: To present a scintillation crystal containing a fluorescent component with excellent luminous efficiency and short decay time while the wavelength of the emitted light being in the visible light region or very near the visible light region and a radiation detection device using the scintillation crystal having an excellent timing resolution capability. Barium chloride (BaCl2) is used as the scintillation crystal. A radiation detection device comprising a barium chloride (BaCl2) crystal as a scintillator and a photomultiplier tube to receive the light from the scintillator wherein the wavelength of the light emitted from the scintillator is between 250 nm and 350 nm and the scintillator is located in a low humidity atmosphere.

Abstract: A novel bath preparation which comprises a whey concentrate of high mineral content and, if necessary, one or more additives commonly used for conventional bath preparations such as inorganic salts, inorganic acid, organic acid, medicinal herbs, fats and oils, dyestuffs, perfumes, alcohols, and polyhydric alcohols.The preparation has the great potential to serve as a curative in the treatment of various disease such as shoulder stiffness, neuralgia, lumbago, rheumatism, etc. It also contributes to beautification.

Abstract: Zinc is advantageously recovered by mixing a zinc-containing material with a bituminous coal etc. to form briquettes, dry distilling the said briquettes to form coked lumps and electrothermically distilling the said coked lumps in an electrothermic distillation furnace.
