|Section2= |Section7= |Section8= }} Thallium(I) bromide (TlBr), a chemical compound, available in an ultra-pure state is a compound semiconductor; used in room temperature X- and gamma-ray detectors and blue sensitive photodetectors; used as a real-time x-ray image sensor; also used as a standard for elemental thallium. The crystalline structure is of cubic CsCl type at room temperature, but it lowers to the orthorombic thallium iodide type upon cooling, the transition temperature being likely affected by the impurities.〔M Blackman et al "The Polymorphism of Thallium and Other Halides at Low Temperatures" (Proc. Phys. Soc. 77 (1961) 471 )〕〔A-V Mudring "Thallium Halides - New Aspects of the Stereochemical Activity of Electron Lone Pairs of Heavier Main-Group Elements" (Eur. J. Inorg. Chem. 6 (2007) 882 )〕〔R. P. Lowndes and C. H. Perry "Molecular structure and anharmonicity in thallium iodide" (J. Chem. Phys. 58, 271 (1973) )〕 A Material safety data sheet (MSDS) is available at http://www.espimetals.com/msds's/thalliumbromide.pdf. Thallium is extremely toxic and a cumulative poison which can be absorbed through the skin. Acute and chronic effects include fatigue, limb pain, peripheral neuritis, joint pain, loss of hair, Central nervous System effects, diarrhea, vomiting, liver and kidney damage. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Thallium(I) bromide」の詳細全文を読む スポンサード リンク
