“…The advantage is that high deposition yields can be reached (99.8%), which makes the method quasiquantitative, and that the quality of the sources is similar to that obtained by vacuum evaporation/sublimation. Generally, the electrodeposition is performed from an aqueous solution and carried out at low voltages [52][53][54][55][56][57][58][59][60][61][62]. If the electrodeposition is applied to an electrolyte consisting of a salt in an organic solution, the technique is called molecular plating [63,64].…”

The final accuracy of a radioactivity measurement can depend to a high degree on the quality of the radioactive sources used. In this paper the most important source preparation technique for radionuclide metrology is described in detail, namely the quantitative preparation of solid sources by drop deposition. Different steps in this source preparation procedure are described, such as preparation of source supports, preparation of dilutions, quantitative drop deposition by the pycnometer method, mass determination, control and improvement of the source quality and the uncertainty calculations involved. Other source preparation techniques of special interest are briefly mentioned and the handling and storage of solutions and sources are discussed.

“…Such sources are generally prepared by molecular beam epitaxy or sputtering technique, using ultrahigh vacuum system [18][19][20][21][22]. An alternative technique is electrodeposition and the potential utility of this technique for the preparation of radioactive source has been well demonstrated [8][9][10][23][24][25]. Very low concentrations of metal ions can be deposited on the surface of a substrate with good reproducibility and high throughput by this method.…”

This paper describes an electrochemical method for the preparation of 57 Co source to be used in quality evaluation of nuclear fuel rods. The electrolytic cell, the experimental set up used and the process of deposition are described. The effect of various parameters such as pH of the electrolyte, bath temperature, current density, content of cobalt in the bath, electrolyte volume in the cell and deposition time were investigated and optimized for maximum deposition. The texture and morphology of the electrodeposited samples were examined by X-ray diffraction (XRD), SEM and EDS analyses. Sources containing ∼ 370 MBq (10 mCi) 57 Co on a circular copper foil of 4 mm diameter could be prepared and encapsulated in an aluminum capsule. Quality assurance tests performed to ensure non-leachability, uniform distribution of activity and stability of the sources gave satisfactory results.

“…In recent years, electrodeposition of radioactive material on a metallic substrate has attracted interest owing to its technical simplicity, reproducibility of results, quick, inexpensiveness preparation, and the ability to accommodate large substrate areas and complex substrate geometries [6][7][8][9][10][11][12][13]. In order to tap the potential of electrochemical technique for the preparation of 63 Ni source, we have reported the preparation of 63 Ni source for the calibration of thermoluminescence dosimeter (TLD) [14] in which we have optimized various experimental conditions to electrodeposit 63 Ni over the copper substrate with high adhesion.…”

Ni source / Electrodeposition / Electron capture detector / Autoradiography / Leachbility / AFM / EDS / SEM / XRDSummary. In this work, we describe a novel electrochemical approach to deposit 63 Ni coatings on the inner surface of a copper annular ring for its application as an ionization source in electron capture detector of gas chromatograph. A description of the electrolytic cell, the process of deposition and the experimental set up used, analysis of the nickel deposit and results are presented in this article. Sources containing ∼ 370 MBq (∼ 10 mCi) 63 Ni could be prepared. The quality of the prepared source in terms of nonleachability, uniform distribution of activity and stability that are necessary before application were evaluated and found to be highly satisfactory.
