Separation of technetium-99m from neutron-irradiated molybdenum(VI) oxide by precipitation as calcium molybdate(VI)

Separation of technetium-99m from neutron-irradiated molybdenum(VI) oxide by precipitation as calcium molybdate(VI). Tanase, M. (JAERI, Tokai, Japan). J. Radioanal. Chem., 41(1), 23-7 (English) 1977. CODEN: JRACBN. DOCUMENT TYPE: Journal CA Section: 71 (Nuclear Technology) A method is discussed for sepg. 99mTc [14133-76-7] from 99Mo [14119-15-4] by dissoln. and repptn. of CaMoO4 [7789-82-4] contg. 99Mo-99mTc. 99mTc can be obtained successfully with a yield of ~80% with a radionuclidic purity 399.7%. On the other hand, by agitating Ca99MoO4 solid with 0.9% NaCl aq. soln., 99mTc can directly be obtained with a yield of ~30% without any impurities.

Shape of Raman effect lines in calcium tungstate molybdate [Ca(WO4)x(MoO4)1-x] mixed crystals

Shape of Raman effect lines in calcium tungstate molybdate [Ca(WO4)x(MoO4)1-x] mixed crystals. Krol, A. V.; Levichev, N. V.; Ryskin, A. I. (USSR). Fiz. Tverd. Tela (Leningrad), 19(3), 781-6 (Russian) 1977. CODEN: FTVTAC. DOCUMENT TYPE: Journal CA Section: 73 (Spectra by Absorption, Emission, Reflection, or Magnetic Resonance, and Other Optical Properties) The shape was investigated of the lines of the Raman scattering of light in mixed crystals of Ca tungstate-molybdate. A considerable broadening was obsd. of the lines and an important mechanism, responsible for that broadening is the scattering of phonons on static inhomogeneities. 7790-75-2 and 7789-82-4 are just another two chemicals used in this study. .
