Radioactivity of Samarium

Nature, 1946
SINCE the discovery of the radioactivity of samarium by Hevesy and Pahl in 19321, several experimenters have examined the emitted radiations in detail2. It is well established that the main radiation consists of I±-particles of range 1.13 ± 0.02 cm., and the experiments of Wilkins and Dempster3 indicate that these particles are emitted by the isotope ...

Vaporization study of samarium trichloride, samarium tribromide and samarium diiodide

Materials Chemistry and Physics, 2003
The vapor pressures of solid (s) and liquid (l) SmCl3, SmBr3 and SmI2 were measured by torsion method and the following selected equations were derived in the temperature ranges studied, SmCl3(s): log p=(11.56±0.30)-(14,950±300)/T (895-941 K), SmCl3(l): log p=(7.88±0.10)-(11,530±100)/T (953-1077 K), SmBr3(s): log p=(11.87±0.30)-(14,470±250)/T (844-925 ...

Samarium diffusion in polycrystalline samarium sulfide

Technical Physics Letters, 2008
The diffusion of samarium in polycrystalline samarium sulfide with a superstoichiometric composition of Sm1.13S has been studied at T = 1000 and 1100°C. It is concluded that Sm atoms predominantly migrate over the boundaries of monocrystalline domains of the polycrystalline sample. The diffusion coefficient varies within D ≈ 10−2−10−3 cm2/s.

Reaction of samarium with hydrogen and nitrogen samarium oxides

Journal of Alloys and Compounds, 1992
Abstract The reaction characteristics between Sm metal and H2 or N2 gas have been studied by means of isochorothermal analysis and X-ray diffraction. Samarium was found to react with hydrogen forming SmH2+x (0⩽×⩽0.63). The reaction is very abrupt, exothermic and takes place at a temperature of between 300 and 525°C depending on the initial size ...

Preparation of samarium monosulfide via samarium naphthalenide

Russian Chemical Bulletin, 1993
Samarium monosulfide in a state amorphous to X-rays was prepared by the successive interaction of lithium naphthalenide with samarium diiodide and a solution of sulfur in THF in inert atmosphere or under reduced pressure under standard (normal) conditions. Samarium monosulfide was transferred to the polycrystalline state (a=5.95 A, NaCl-like structure)

Samarium 153Sm Lexidronam

Drugs & Aging, 1997
Samarium 153Sm lexidronam is a medium energy beta-emitting radioisotope chelated to the tetraphosphate, ethylenediaminetetramethylenephosphonic acid (EDTMP). 153Sm has a physical half-life of 1.9 days. Samarium 153Sm lexidronam concentrates in bone tissue and has a metastatic lesion: normal bone ratio of 4.

The standardization of samarium-153

International Journal of Radiation Applications and Instrumentation. Part A. Applied Radiation and Isotopes, 1987
Samarium-153 has been standardized by 4 pi beta liquid-scintillation counting, with an uncertainty of 0.4%. The probability per decay for the 103.2-keV gamma ray was measured, using two germanium detectors, to be 0.298 +/- 0.004. The half life, based on liquid-scintillation measurements over 6.4 half lives and pressurized-ionization-chamber ...
